    Hi, I plan to go to Kamokawa Sea World from Tokyo on Friday early morning with my son.
    Hyperdia recommend to go with Wakashio 1 and stop at Katsuura at 8:46 then transfer to Sotobu Line at 8:48.
    I have only 2 min to transfer. I can’t find any map or detail of Katsuura Station or arrival/departure platform at Katsuura.
    My Question, Do I have time enough to transfer the train within 2 min with my children. Seem like If I mis this train I have to wait about an hours for next train.


    • Hi Itim,

      There are two platforms in Katsuura station but I think you will change trains at same platform. In most of cases, 2 minutes transfer time is on purpose. I’m optimistic and you can make it.

      Did you manage to change trains at the Katsuura station on time? ie within that 2 minutes. Am thinking of taking the same this week to Kamogawa seaworld. Cheers.

      • Itim says:

        Jusr finished my Japan trip.
        Yes, we did it. It’s stop on the same track and another train was waiting there.

    Hi! May i know how much is the one way ticket and round trip ticket from tokyo to ara-kamogawa using this line?
    Thanks!! 🙂

  3. Rin says:

    Hi Takeshi-san, thanks for the previous reply to my questions, I can’t reply directly to your answer as I am typing via phone and I can’t see any reply button. But I just received an update from the university about the schedule and sadly it seems like I won’t be able to travel to Tokyo that much (only about 2-3 round trip) , so I think buying JR East Pass will be a loss for me. So my question :
    Can I buy the ticket for Wakashio in Awa-kamogawa station? And just want to make sure, I am not obliged to make any reservation right?
    Thank you in advance 🙂

  4. Rin says:

    I will be having summer program in of the university in Chiba, and seems like the closest station to the univ is Futomi Station.
    It will be from 6th to 29th July 2015.
    I will have classes on weekdays, but on weekends I would like to go to Tokyo.
    Here’s my questions :
    1) Seems like JR East Pass will be more effective for me since I won’t be going on consecutive days. But since I’m going to stay in Japan for 3 weeks + several days so I have to but it twice so I’d like to ask, is the pass only available for sale in big train station?or is it available in Awa-kamogawa? If it’s not available in Awa-kamogawa could you refer to the nearest train station that selling the pass?
    2) I just want to confirm my route : Futomi station –> Awa-kamogawa station–> ride the ltd express wakashio –> Tokyo station. And then from Tokyo station I can ride on the Yamanote Line to commute to places like Akihabara, Ikebukuro, Shibuya,etc. Is that right? And is that all covered by the JR East Pass?

    Sorry for the long questions, hope you won’t mind, thanks in advance 🙂

    • Hi Rin,

      1) Actually Narita airport station is only place to sell this pass in Chiba pref. If you arrive in Narita, you can purchase it when you arrive. You don’t need to activate right away. You can pick up the date when you want to start.

      2) That is right. All part of your trip is covered by JR east pass.

    My Cousins are planning to visit Awa-Kamogawa tomorrow from Tokyo and would like to enquire whether they can use their JR Pass for travelling by Ltd. Express Wakashio ? Or could suggest alternate travel using JR pass.

    • JPRail says:

        Dear Takashi-san,

        Thank you for your email reply regarding the use of JR pass for the Wakashio express.

        On Thursday, my cousins are planning to go to the Tateyama Alpine Route starting early in the morning.
        Could you please inform whether travel on Ltd. Express Hakutaka2 (Tokyo to Toyama route) and Ltd. Express Azusa1 (Shinano-Omachi to Tokyo route) is covered by JR Pass ?
