If you want something different on your trip to Kansai area, Kansai Wide Area Pass is highly recommended. I always recommend to use Kansai Thru Pass and Kansai Area Pass to travel within Kansai area, such as Kyoto, Nara, Kobe, Osaka, Wakayama, Himeji. But Kansai Wide Area Pass covers outside these areas, such as Shingu, Okayama, Kinosaki Onsen, Takamatsu. And this pass is valid for 5 days. It makes your trip more interesting.
This will be on sale in March, 2015 and will replace currently selling Sanyo Area Pass. This pass includes all Sanyo Area Pass coverage area, such as Kyoto, Osaka, Kobe, Himeji, Hiroshima, Miyajima and Hakata. This pass also includes Sanin area (Matsue, Izumo, Tsuwano), Hikone, Maibara, Tsuruga, Wakayama and even part of Shikoku. It is wider coverage area, cheaper price and longer duration.
I published several post about the limited express trains to Sanin area, such as Super Oki, Super Matsukaze, Super Inaba, Super Hakuto and Hamakaze. But there are some more trains from Osaka and Kyoto to Kinosaki-Onsen area. And there are several gateway stations. You might be confused.
Limited Express Super Oki (スーパーおき) is operated between Tottori (鳥取), Yonago (米子) and Shin-Yamaguchi (新山口). This train connects all major cities in Sanin area with Shinkansen station Shin-Yamaguchi. Especially you can access to west part of Sanin area, such as Masuda (益田), Hamada (浜田), Odashi (大田市) where is UNESCO World Heritage Iwami Ginzan Silver Mine gate station, this train is your choice. And you can use this train for transfer among Matsue (松江), Izumoshi (出雲市) and other cities in Sanin area. Other limited express Super Matsukaze is operated between Tottori and Masuda. You can use both trains for inter-city transfer in Sanin area. Moreover don’t forget than Tsuwano (津和野) is on the way. This small town is called “Sanin’s little Kyoto”.
Limited Express Super Matsukaze (スーパーまつかぜ) is operated between Tottori (鳥取), Yonago (米子) and Masuda (益田). This train connects all major cities in Sanin area. Matsue (松江) has castle and Samurai district. Izumoshi (出雲市) is very well known by Japan’s second most important shrine, Izumo Taisha. Odashi (大田市) is a gate station to UNESCO World Heritage Iwami Ginzan Silver Mine. You can travel all these cities by Super Matsukaze. It is no doubt that this train is essential to travel in Sanin area. This train is fully covered by JR pass and JR West Sanyo Sanin Area Pass.
Limited Express Super Inaba (スーパーいなば) connects Okayama (岡山) with Tottori (鳥取). It is connected with Shinkansen and Sunrise Izumo/Sunrise Seto. This is the fastest access to Tottori from Tokyo by Sunrise Seto and Sunrise Izumo. If you access to Tottori from Okayama and to the west from Okayama, such as Hiroshima, Hakara and all places in Kyushu and Shikoku. But this train goes through non JR line, Chizu Kyuko Railway. It is operated on same route as Super Hakuto between Kamigori and Tottori. That means you need to pay extra if you use this train by Japan Rail Pass. If you don’t want to pay extra, get on Limited Express Yakumo from Okayama to Yonago and transfer to another Limited Express Super Matsukaze or Limited Express Super Oki to Tottori. However travel time of this combination is at least 1.5 hours longer than Super Inaba. Sometimes it may take more because of connection at Yonago.
Limited Express Super Hakuto (スーパーはくと) connects Kyoto (京都), Shin-Osaka (新大阪), Osaka (大阪), Sannomiya (三ノ宮) and Himeji (姫路) with Tottori (鳥取) and Kurayoshi (倉吉). This it the fastest and most frequent direct train service to Tottori from Osaka, Kobe and Kyoto. But this train goes through non JR line, Chizu Kyuko Railway. That means you need to pay extra if you use this train by Japan Rail Pass. If you don’t want to pay extra, Limited Express Hamakaze is available between Osaka and Tottori. However there is only one round trip and travel time is 1.5 hours longer than Super Hakuto.
