Suo-Oshima Onsen Without a Car: Which Bath Is Realistic by Bus?
Compare bus routes from Obatake Station to Ryuzaki, Yuyu Land and Shioburo Hoyokan, including transfers, walking legs and return-trip caveats.
Summary: From Obatake Station, Ryuzaki Onsen has the clearest bus-and-walk route: about 37 minutes to Anko, then a 10-minute walk. Yuyu Land takes a second bus on the general-rider Shiraki Line, while the final walk to Shioburo Hoyokan is not clearly set out in the facility’s access information. Pick one bath and confirm the return trip before setting off.

Start with the bus back to the station
Suo-Oshima is possible without a rental car, but its buses are not frequent urban service. A route that looks short on a map can involve a long wait or a connection timed around school days. Before leaving Obatake Station, choose the return bus you can live with; that decision determines how long you can stay at the bath.
The public-transport timetable in force was revised on April 1, 2026. It separates the island bus network from school-bus routes that also carry general passengers, and some services vary by weekday, weekend or school holiday. Recheck the timetable for your date rather than assuming that a bus shown on a map runs every day.
For Ryuzaki, only some Oshima Main Line departures serve Anko. For Yuyu Land, the published route uses the general-rider Shiraki school-bus line and identifies the stop as “Katazoe (Yuyu Land-mae).” The timetable separates weekday, weekend and school-holiday conditions. Make sure you can connect back through Hirano or Shimo-Tashiro as well; the fares for the transfer depend on the actual service and are not included in the bath prices below.
Ryuzaki is the simplest route to understand
Take a bus from JR Obatake Station to Anko (about 37 minutes), then walk about 10 minutes to Ryuzaki Onsen. Not every island-bound departure serves every branch stop, so match the bus to “Anko” on the timetable instead of boarding by direction alone.
That final walk is manageable for many visitors, but it is still a walk along a local road after a bus ride. Allow time for the return leg before bathing. Ryuzaki closes its onsen admission at 20:30, but that does not mean a useful bus back to the station will still be running at closing time. Its facility guide covers the bath and current access details.
Yuyu Land requires a connection at Hirano
For Katazoegahama, take the bus from Obatake Station toward Hirano; the tourism site estimates about 50 minutes to Hirano. From there, transfer to the town’s Shiraki Line, a school-bus service that is also open to general passengers. The ride to Katazoe is about five minutes, followed by a short walk to Yuyu Land.
This route works best when the beach park is part of the day, not when the bath is the only reason to go deep into the island. Check both directions of the Shiraki Line and its operating-day notes before travelling. If the connections leave too little time at the beach or bath, choose Ryuzaki instead. Yuyu Land’s hours and facilities are in the Katazoegahama Yuyu Land guide.
The route is most worthwhile if you mean to spend a few hours at Katazoegahama, perhaps swimming or staying at the campsite, before bathing. A brief soak alone may not justify two buses each way. The published town timetable names “Katazoe (Yuyu Land-mae),” so this is a real public-transport option, but service days and school breaks still matter; do not treat the rough 50-minute first leg as a direct or frequent bus.
Shioburo Hoyokan: do not guess the last mile
Green Stay Nagaura is near the island’s bridge entrance by car, but proximity does not guarantee an easy walk from a bus stop. The facility’s own access page gives driving directions and a phone number, while the town timetable covers the wider bus network; neither clearly identifies a recommended stop-to-door walk for a first-time visitor. Ask the facility at 0820-79-0021 which bus and stop are practical that day, or arrange a taxi from Obatake Station.
The saltwater bath and the rest of the facility have had separate service notices. The June 30, 2026 reopening notice said the saltwater bath would return separately; a later town update on August 13 announced the salt-bath reopening. Since equipment notices have changed several times this year, check the latest facility or town announcement before travelling. The Shioburo Hoyokan guide explains the distinction and current published hours.
Keep the day to one bath
Ryuzaki uses the Anko bus stop and a walk; Yuyu Land involves a transfer to the Shiraki Line; Shioburo needs a confirmed last-mile plan. Trying to chain two of them by public transport leaves little room for a missed connection, a slow meal or a longer soak. With a car, the choice can follow the day’s geography. Without one, a single destination and a protected return connection make a much more dependable half-day.
