Rates are the lowest totals on Rakuten Travel for 2 adults, 1 room, 1 night with dinner and breakfast (tax included, retrieved November 1, 2026). They come from 9 Wednesdays and Sundays between November 18, 2026 and January 20, 2027, and the date differs by inn (each section says which). Early-booking, last-minute and smaller-meal plans are left out, and room and plan conditions are in each section. These are not necessarily the lowest prices, and Saturdays and long weekends can cost more.
2. Getting to Shima Onsen
By train, take the limited express “Kusatsu Shima” from Ueno Station to Nakanojo Station (about 120 minutes), then the bus (about 40 minutes) or a taxi (about 20 minutes). The Kanetsu Kotsu bus from Nakanojo Station costs ¥1,150 for adults, and from the last stop, Shima Onsen, Sekizenkan’s main building is a 2-minute walk. There is no regular bus from Jomo-Kogen Station (Sekizenkan access page, Japanese).
By car, it is about 39 km, around 60 minutes, from Shibukawa-Ikaho IC on the Kan-Etsu Expressway via National Routes 17 and 353 (from the Rakuten Travel facility information).
The Shima Onsen Association website describes direct bus plans between Tokyo Station, Kawagoe Station West Exit or Haneda Airport Garden and Shima Onsen, and a 2-day free bus pass for the Nakanojo Station–Shima Onsen route (Shima Onsen Association, Japanese).
The inns in Hinatami, deeper in, are more than 20 minutes on foot from the last bus stop, so book the inn’s shuttle or plan to go by car.
