4. Five rules for a successful day trip

  1. Ryokan day use is mostly 11:00–15:00 — plan a morning arrival
  2. Weekends bring more 'no day use' days. Go midweek or choose public baths (sotoyu, municipal)
  3. Bring your own towel (saves ¥200–400 rental)
  4. Reserve limited-express seats both ways in advance (return unreserved cars fill up)
  5. Leave luggage at your hotel. Station lockers cost ¥400–700

5. When staying over is the better deal

Kinosaki, Shirahama and Kusatsu cost over ¥10,000 in return fares alone. Add a weekday room with two meals (from ¥15,000) and it's still cheaper than two day trips — and you get the baths at night and dawn. Check weekday rates via Agoda and Trip.com on each onsen-town page here before deciding.
