I have shared a day trip sample itinerary of Fuji and Hakone before.
But this itinerary covers both Lake Kawaguchi and Hakone areas in one day. It is very tight and many places are not covered. If you can spend two days, you can enjoy Fuji and Hakone areas one day each. You can visit many more places easily.
In this sample itinerary, I tried to put most of popular spots in these areas. And also this plan includes Fuji Shibazakura festival which is most popular event in spring. You can do this trip from Tokyo to Tokyo. You also can squeeze this trip between Tokyo and Osaka. You can drop by this area on the way to Osaka or Kyoto from Tokyo or versa.
This itinerary has been created by timetable in March, 2018. If you try to do this plan, please check the updated timetable before you go.
If you look for the itinerary to Hakone or Fuji (Lake Kawaguchi area) only, please see the link below. You may get more information about access to these places and some sample itineraries:
How to build the trip plan to Hakone. Various sample itineraries of Hakone
Purchase Fuji Hakone Pass
This deal covers both Fuji and Hakone area. It is valid for 3 days. This is two days itinerary but this deal is cheaper than total fares anyway. Please get this pass day before departure day because you will be busy on departure day.
Odakyu Railway – Fuji Hakone Pass official site
There are two types of Fuji Hakone Pass, Shinjuku departure and Odawara departure. If you intend to use JR Pass, JR East Pass or Tokyo Wide Pass, you may purchase Odawara departure. Because Odawara departure does not include Shinjuku to/from Kawaguchiko or Odawara. You may use your pass for this segment to save the total cost. If you squeeze this itinerary between Tokyo and Osaka (or Nagoya or Kyoto), you may use Odawara departure version anyway. You need only one way to Fuji. It does not make senses to use Shinjuku departure because it includes round trip between Shinjuku and Fuji/Hakone.
If you want to take limited express train “Romancecar” from Hakone to Shinjuku, you may book when you purchase a pass. Limited Express seat fee is extra on top of Fuji Hakone Pass. But this express train takes you to Shinjuku directly from Hakone-Yumoto. Interior is very comfy. It is highly recommended.
Day 1 Shinjuku (Tokyo) to Lake Kawaguchi
On the first day of trip, enjoy sightseeing around Lake Kawaguchi area and stay overnight
Shinjuku to Lake Kawaguchi
If you use Fuji Hakone Pass Shinjuku departure version, you will take the express bus from Shinjuku bus terminal.
Shinjuku 07:45 (Express bus) 09:30 Kawaguchiko station (Lake Kawaguchi)
This bus schedule is based on 2017-18 winter schedule. The schedule may be changed when you travel. Please confirm the bus timetable when you build your trip plan.
Shinjuku – Fuji Express Bus timetable
If you use JR Pass, JR East Pass or Tokyo Wide Pass, you may take the trains via Otsuki.
Shinjuku 07:30 (Limited Express Azusa 3) 08:30 Otsuki 08:35 (Fuji Kyuko Railway) 09:31 Kawaguchiko (Lake Kawaguchi)
Most of the trains from Otsuki depart from Fuji Kyuko Railway platform. But the train in this trip schedule is JR local train which goes from JR line to Fuji Kyuko line. This train is irregular and depart from JR train platform in Otsuki station. You do not need to enter Fuji Kyuko Railway Otsuki station. Please see the link below to find more information about Otsuki station.
Otsuki station guide. How to transfer from JR train to Fuji Kyuko train
This is based on 2017-18 winter schedule. Train schedule may be changed when you travel. Please confirm the train timetable when you build your trip plan.
After you arrive in Lake Kawaguchi, you have two options in the morning.
Option 1, Fuji Shibazakura Festival
This is very popular spring festival in Mt. Fuji area.
Kawaguchiko 9:40 (Shuttle bus “Fuji Shibazakura Liner”) 10:11 Shibazakura festival venue 11:30 (Shuttle bus “Fuji Shibazakura Liner”) 12:00 Kawaguchiko
This festival is very popular and very crowded. You should visit this at the beginning in your trip to minimize the congestion.
Option 2, Fuji Subaru Line 5th station
Kawaguchiko 9:50 (Fuji Kyuko route bus) 10:45 Fuji Subaru Line 5th station 11:40 (Fuji Kyuko route bus) 12:25 Kawaguchiko
In summer and autumn, you may visit 5th station at the halfway of the summit of Mt. Fuji. This is the highest point to visit without mountain climbing. You can visit 5th station in even spring season if you want.
Lunch time in Kawaguchiko and see Mt. KachiKachi Ropeway, Lake Kawaguchi Cruise and/or walk around Lake Kawaguchi
After Shibazakura Festival or 5th station sightseeing, you have a lunch time around Kawaguchiko station. You have two hours break at Kawaguchiko station. You can take Gondola on Mt. KachiKachi or short cruise on Lake Kawaguchi.
If you take the gondola to go up to Mt. Kachikachi, you may take the following schedule.
Kawaguchiko station 13:00 (walk 15 minutes) 13:15 Mt. Kachikachi (Kachikachiyama) Ropeway (3 minutes by godola) Observation spot (3 minutes by gondola) 14:05 (walk 15 minutes) 14:20 Kawaguchiko station
Mt. Kachikachi Ropeway official site
If you take the lake cruise, you may take the following route:
Kawaguchiko station 13:10 (walke 10 minutes) Lakeshore boarding pier 13:30 (20 minutes Lake cruise) 13:50 (walk 10 minutes) 14:00 Kawaguchiko station
Kawaguchiko Lake Cruise “En Soleil”
In this lunch break, you cannot do both. And also if you travel in summer time, you come back to Lake Kawaguchi around 16:30. You still have a time to take lake cruise if you like. Please remember that you will take ropeway and lake cruise in Hakone too. So you can skip these attractions and just walk around Lake Kawaguchi.
These two attractions are not covered by Fuji Hakone Pass. If you intend to take both, you can purchase discount combo ticket for gondola and cruise at Mt. Kachikachi Ropeway ticket booth. It is sold at 1,300 yen. You will take ropeway and sightseeing cruise in Hakone too. Especially sightseeing cruise is much longer and ship is much bigger in Hakone. You may consider which attraction you really want to take and compare with Hakone’s.
Hotels in Tokyo
Hotels in Hakone
Hotels in Lake Kawaguchi (Kawaguchiko)
Visit Chureito Pagoda
Kawaguchiko station 14:29 (Fuji Kyuko railway local train) 14:43 Shimo-Yoshida 15:58 (Fuji Kyuko railway local train) 16:12 Kawaguchiko station
You may have seen the photo of Chureito Pagoda. This is very famous spot especially in cherry blossom season. You can enjoy the view of cherry blossom, pagoda and Mt. Fuji at same time. It may be the best place to see cherry blossom in Japan.
Chureito is one of the building in the shrine. Official name of this place is Arakura Fuji Sengen shrine. This entrance of the shrine is only 10 minutes away from Shimo-Yoshida station of Fuji Kyuko Railway. But the pagoda is located about 15 to 20 minutes away from the station.
Unfortunately the train does not run very frequently between Kawaguchiko and Shimo-Yoshida. There is no earlier trains to get Shimo-Yoshida.
Day 2 Lake Kawaguchi – Gotemba – Hakone – Odawara – Shinjuku (or Nagoya, Kyoto, Osaka)
Leaving from Lake Kawaguchi and proceed to Hakone area. You can drop by Oshino Hakkai or Gotemba Premium Outlet on the way.
Lake Kawaguchi to Oshino Hakkai
Kawaguchiko station 09:00 (Fuji Kyuko bus) 09:23 Oshino-Hakkai
Enjoy 1 hour walk in Oshino Hakkai.
Oshino Hakkai to Hakone Venetian Glass Museum via Gotemba and Sengoku
Oshino Hakkari 10:23 (Fuji Kyuko bus) 11:15 Gotemba station 11:45 (Odakyu Hakone Highway Bus) 12:05 Sengoku
Hakone Venetian Glass Museum is 1km away from Sengoku bus stop.
Actually you may take one earlier bus because the bus to Sengoku from Gotemba station at 11:15. It is exactly same time as arrival time in Gotemba. If you can catch this earlier bus, the bus stop at the museum. 1km walk is not required and you have extra 30 minutes at Sengoku
Anyway you have two hours at Sengoku. You can visit the museum and eat lunch. You can eat in the museum or around Sengoku bus stop.
How to put Gotemba outlet in the trip plan
Gotemba Premium Outlet is very popular spot for shopping spree. If you give up Oshino Hakkai, you can drop by outlet easily.
Kawaguchiko station 08:30 (Fuji Kyuko bus) 10:05 Gotemba Premium Outlet 11:40 (Hakone Tozan Bus) 12:02
You have 1.5 hours at outlet and catch up with the original schedule at Sengoku. However you have to leave Kawaguchiko 30 minutes earlier. And also you may carry lots of shopping bags while sightseeing. Even if you can find the lockers at each places, it may bother you.
Sengoku to Togendai and Lake Cruise
Sengoku 13:56 (Hakone Tozan Bus) 14:13 Togendai 14:20 (Hakone Sightseeing Cruise) 15:25 Togendai
Take a bus to get Togendai. Togendai is the hub of Hakone. This place is the departure point of lake cruise, ropeway, express bus and local bus.
After arrival at Togendai, hop on Hakone Sightseeing Cruise and enjoy the scenery around the lake.
Togendai to Owakudani
Togendai (16 minutes by Hakone Ropeway) Owakudani
Owakudani cannot be missed in Hakone. This is an active volcanic area. You can experience lots of steam and bubbling hot springs along the short trail. Boiled egg that is cooked in this hot spring water is very famous food at Owakudani. Just try to eat it.
Hakone Ropeway is operated until 16:15 in winter season. Please make sure how much you can stay in Owakudani. You take ropeway again to get Sounzan. Usually it takes 20 minutes to walk the trail. The operation time is extended to 17:00 in summer season (March to November).
Owakudani to Hakone-Yumoto via Sounzan and Gora
Owakudani 16:00 (16 minutes by Hakone Ropeway) 16:08 Sounzan 16:17 (Hakone Cable Car) 16:27 Gora 16:38 (Hakone Tozan Railway) 17:20 Hakone-Yumoto
There are many more bus services available to Hakone-Yumoto. But many buses take old road. In this sample, I picked the bus which takes new road. Trip time is 25 minutes to get Hakone-Yumoto. If you take a bus which run on old road, trip time is 45 minutes. Please make sure which bus you will take.
Hakone Tozan Bus official site, Route search
Hakone-Yumoto is the biggest hot springs town in Hakone. There are lots of restaurants and shops. You can eat and/or shop there. You can take just an Onsen bath without overnight stay. I have two recommended Onsen facilities. I put the links but these are unfortunately in Japanese. These two Onsen facilities are located within 5 minutes from Hakone-Yumoto station by walk.
Kappa Tengoku
It is located just behind Hakone-Yumoto station. It is open until 22:00. You can eat some light meals and drinks there too.
Yajikita no Yu
It is located in Hakone-Yumoto ryokan area. It is open until 21:00. This facility does not have a dining.
But if you move to Osaka, Kyoto or Nagoya, you do not have time to drop by Hakone-Yumoto.
Hakone-Yumoto to Shinjuku
Hakone-Yumoto (Odakyu Railway 1.5 hours by Romancecar without transit, 2 hours with transit at Odawara) Shinjuku
Odakyu railway train runs until late night. I recommend you to take Odakyu Railway’s limited express train, “Romancecar”. It connects Hakone-Yumoto and Shinjuku directly and it offers very comfy accommodation. You have to pay extra 890 yen for seat fee but it is worth paying. Please see the timetable of Romancecar in the link below:
Odakyu Railway Romancecar timetable
If you do not want to pay any extra, you can take local train to Odawara from Hakone-Yumoto and change to a regular commute train to Shinjuku. There is no direct trains from Hakone-Yumoto to Shinjuku other than Romancecar.
Hakone-Yumoto to Osaka, Kyoto or Nagoya
Hakone-Yumoto 17:33 (Odakyu Railway local train) 17:51 Odawara 18:08 (Tokaido Shinkansen Hikari 523) 19:19 Nagoya, 20:13 Kyoto, 20:26 Shin-Osaka
You can get Odawara by Odakyu railway local train and catch Shinkansen at Odawara. This Shinkansen “Hikari 523” is the last train which you can get Nagoya, Kyoto or Shin-Osaka from Odawara without changing trains. If you do not mind to change trains, there are some more trains later than 18:08 departure.
Other later train connections
Hakone-Yumoto 18:44 (Odakyu Railway local train) 18:59 Odawara 19:13 (Tokaido Shinkansen Kodama 803) 19:28 Mishima 19:47 (Tokaido Shinkansen Hikari 523) 21:08 Nagoya, 22:00 Kyoto, 22:13 Shin-Osaka
Hakone-Yumoto 19:33 (Odakyu Railway local train) 19:48 Odawara 20:05 (Tokaido Shinkansen Kodama 68) 20:56 Shizuoka 21:10 (Tokaido Shinkansen Hikari 533) 22:09 Nagoya, 23:02 Kyoto, 23:16 Shin-Osaka
If you want more time in Hakone, you may use one of these above train connections.
Sample trip plan from Osaka, Kyoto, or Nagoya to Tokyo
If you want to squeeze this trip plan on the way to Tokyo from Osaka, Kyoto or Nagoya, you may reverse this trip plan. But the location to stay overnight is different. It is hard to reach Lake Kawaguchi on day 1. In this case, your overnight place is Hakone. That means the time in Lake Kawaguchi is a bit shorter than the original plan above. If you skip Oshino Hakkai, you can have one more hour in Lake Kawaguchi area.
Day 1

Dear Takeshi-san,
I am going to Fuji for 1 night on 25th Mar 2020 and I will continue to Kyoto.
Which place should i visit first for 2 days 1 night trip before heading to Kyoto?
Hope you can help me out for itinerary. Thank you beforehand.
Kindness regards,
Sreymom (Siri)
Hi Sreymom san,
You can visit Fuji Lake Kawaguchi area first. Because you will catch the Shinkansen to Kyoto from Odawara. Odawara is a step away from Hakone Yumoto.
You can follow my sample itinerary in the post above.
Cheers,
Takeshi / JPRail.com
Hi Takeshi,
I am going to Hakone/Fuji from 24 – 26 April 2020.
Please see my proposed itinerary below:
Day 1: Shinjuku to Hakone
– Go to Ōwakudani Station and Togendai Station
– Explore Lake Ashi (Hakone Sightseeing Cruise)
– Overnight at Hakone
Day 2: Hakone to Gotemba to Kawaguchiko
– Bring luggage to Gotemba (put in station)
– Afternoon: Go to Kawaguchiko
– Visit Chureito Pagoda, Mt. KachiKachi Ropeway, Lake Kawaguchi Cruise and/or walk around Lake Kawaguchi
– Overnight at Kawaguchiko
Day 3:
– Go to Fuji Shibazakura Festival
– Afternoon go to Oshino Hakkai and Yamanakako Hananomiyako Park
– Overnight at Kawaguchiko
I have a few questions:
1. Is it worth it to get the Fuji Hakone 3-Day pass? I will be going to Takayama from Kawaguchiko.
2. Does Gotemba have luggage storage?
3. Is my itinerary too rush/too slow?
THANK YOU SO MUCH FOR YOUR HELP!
Hi Desrene,
1. I recommend you to buy a regular ticket from Shinjuku to Odawara and Fuji Hakone Pass Odawara at 7,180 yen. One way fare from Shinjuku to Odawara is only 900 yen. This combination is much cheaper than Fuji Hakone Pass Shinjuku at 9,780 yen.
2. There are lockers at Gotemba station. You may see a photo in the link below:
https://locker1.exblog.jp/20154881/
In Gotemba outlet, there are lockers too. But I have no idea about the demand of these lockers. Please expect that all lockers may be full. As far as I know, there is no more lockers in Gotemba area.
3. It will be busy trip but it is feasible.
Cheers,
Takeshi / JPRail.com
Hi Takeshi, thank you for your reply. Will it be better to skip Gotemba if too busy? Thank you!
Hi Desrene,
If you skip Gotemba, it’s much easier. Because it takes more than 2 hours from Hakone to Lake Kawaguchi.
Cheers,
Takeshi / JPRail.com
Hi Takeshi,

I have a few questions:
1. Is this itinerary ok?

3. Is Mt. Fuji Sta. Takayama bus covered in Fuji Hakone Pass?
Thank you! 🙂
Hi Desrene,
1. Yes.
2. Don’t add any more places. You have already put many places.
3. No, it’s not covered. Takayama is way far from Kawaguchiko. You must pay a full fare of it.
Cheers,

Hello Takeshi-san,
I am planning to have a 2 days 1 night trip to Fuji-Hakone with my families. Will arrive Tokyo early morning @ 26th Jan 0200hrs.
– It is possible for me to get the express bus seat from Shinjuku to Kawaguchiko since I will purchase the Fuji Hakone Pass at the same day?
-When is the last public transportation available from Kawaguchiko to Hakone ?
Thanks for your advise in advanced
Best regards,
Eva
Hi Eva san,
Usually you can book a seat on the travel day because there are lots of running:
http://bus-en.fujikyu.co.jp/highway/detail/id/1
Please see the bus schedule from Kawaguchiko to Gotemba. When you go to Hakone, you must change a bus at Gotemba:
http://bus-en.fujikyu.co.jp/route/detail/id/1/
You can find all timetables in Hakone which includes the bus from Gotemba in the following link:

Hello Takeshi-san,
Your itinerary is really helpful. May I ask for some additional advise? My friend and I will be traveling from Nagoya heading Tokyo and plan to visit the Lake Kawaguchiko area and Hakone (1 night & 2 days).
4/7: Arriving Odawara in the evening
Day 1 4/8: Day trip in Hakone
Day 2 4/9: Day trip to Kawaguchiko and then head to Shinjuku or Tokyo.
Question:
1. What area do you recommend to lodge on the 1st night to minimize travel time?
2. We travel from USA so we will both have a medium size luggage. Clearly we do not want to bring our luggage around with us on both days. What do you recommend to do to store our luggage? or is there any service that ship our luggages from the Odawara Station to the Kawaguchiko Station?
Hope you can help me. Thanks!
regards,
Judy (from California)
Hi Judy san,
1. Hakone-Yumoto is recommended. It is about 20 minutes away from Odawara. Hakone Yumoto is one of the biggest onsen town in Hakone.
2. The easiest way is shipping your large size luggage from Nagoya to Tokyo. Just pack small for one night two days. Most hotels have contract with shipping company. So you may ask your hotel in Nagoya. There is no shipping service from Odawara to Kawaguchiko.
Cheers,

Hello Takeshi-san,
I am planning to have a 2 days 1 night trip to Fuji-Hakone with my families. There are total 6 adults and 3 kids, all below 5 years old. We will be in Tokyo early May, during Golden Week, any suggestion what would be the best option to travel
– Is weekday better?e.g.: Depart on Tue (5th May) and return on Web (6th may)
– Is taking train better option than bus due to road congestion during PH?
– can you remommend places for stay with reasonable price?
Thanks for your advise in advanced
Best regards,
Eva
Hi Eva san,
May 5th and 6th will be holidays. These dates are in Golden Week. If you travel after 7th, it will be weekday and it is much easier to travel. Please see the link below to find the busy period:
https://jprail.com/travel-informations/travel-tips/2020-busiest-period-to-travel-by-train-tips-to-book-your-seat-in-even-during-the-busy-period.html
It doesn’t matter whichever you take a train or a bus. As long as you travel in Golden Week, both will be busy. And also Fuji has been quite popular in these days. Even weekday is busy now. Sometimes a train is packed in weekday by many oversea tourists. But if you travel to Fuji Hakone from Tokyo, you will use Fuji Hakone Pass. It covers a bus from Shinjuku to Kawaguchiko. You cannot take a train to get Kawaguchiko. But if you go to Hakone first, your choice is a train. You cannot take a bus to get Hakone.
https://www.odakyu.jp/english/passes/fujihakone/
I think it’s hard to find the place to stay overnight at reasonable price in Fuji Hakone area. Just check the price, location and facility to choose as your need.
I don’t think I encourage you to visit there. But I just wanted to let you know the real info.
Cheers,
Takeshi / JPRail.com
Hi Takeshi-san, I have a plan to visit kawaguchiko in January 2020,

2. I heard that there will be kawaguchiko winter fireworks on January and will be held at 20:00-20:20 pm. If we want to watch it is there any bus to tokyo after that show?
Thank you,
Hi lina san,
Please find the bus timetable in the link below. Some bus take you to 5th station from Shinjuku directly. As long as the weather is okay, the bus goes to 5th station. Of course if the weather is severe, it will be suspended.
http://bus-en.fujikyu.co.jp/highway/detail/id/1
You also find some more bus trips between Kawaguchiko and 5th station in the link below:

You cannot go back to Tokyo after fireworks unfortunately. Please check the timetable in the first link above.

Hello Takeshi-san,
Need some advise. Me and 2 other friends are planning for a 3 days trip to Mt. Fuji (day trip) and Hakone (2 nights & 2 days).
Day 1 @Mar 02: Shinjuku to Kawaguchiko then to Hakone (evening).
Day 2 @Mar 03: Hakone
Day 3 @Mar 04: Hakone, and then, Hakone back to Shinjuku (around 6pm).
Question:
1. Given the above itinerary, is it worth to buy the Fuji Hakone Pass?
2. Is there a train to take from Kawaguchiko to Hakone?
What station in Hakone?
What is the last train operating between Kawaguchiko to Hakone?
3. We do not want to bring our luggage around with us around Mt. Fuji.
Is there locker that we can rent at Kawaguchiko station?
Hope you can help me. Thanks!
regards,
Jessy
Hi Jessy san,
1. Yes. It gives you a big saving.
2. There is no trains runnning between Kawaguchikko and Hakone. The bus is only choice as I used it in the sample. So you have to take a bus from Kawaguchiko to Gotemba station or Gotemba outlet. And then take another bus to Hakone.
Kawaguchiko to Gotemba
http://bus-en.fujikyu.co.jp/route/detail/id/1/
There are lots of bus routes in Hakone. You may find all timetables in the link below:
https://www.hakonenavi.jp/e_catalog/english/book/html5.html#page=1
3. Yes. There are lots of lockers. Even if all lockers are occupied, you may ask the luggage storage service in the station. Kawaguchiko station is small and you can find the storage service signage easily.
Cheers,
Takeshi / JPRail.com
