Onsen and local food — what to eat after the bath, town by town
Onsen eggs, hell-steamed dishes, crab, onsen manju. Onsen-town food is often cooked in the spring itself or grew up around it. Fourteen pairings not to miss.
1. Dishes cooked in the spring
- Onsen eggs: 20–30 minutes in a 70°C source. Hakone Ōwakudani's black eggs (shells blackened by iron sulfide); egg-boiling stations outside communal baths in Beppu, Nozawa and Gero
- Jigoku-mushi 'hell steaming' (Beppu Kannawa): vegetables, seafood and meat steamed over fumaroles. Do it yourself at the Jigoku-mushi Kōbō Kannawa (seat charge plus ingredients, ¥1,500–2,500 per person)
- Onsen porridge and onsen tofu (Ureshino): mildly alkaline water melts tofu into custard. A breakfast staple
- Onsen manju: steamed buns said to originate in Ikaho. Eat them hot while walking

3. Understanding ryokan meals
- Kaiseki: appetiser → soup → sashimi → grilled → simmered → fried → rice → fruit. Allow 1.5–2 hours
- Dinner and breakfast included is standard. Dinner starts at 18:00 or 18:30, breakfast 7:30–8:30. Arrive late and the food is cold
- Where: in your room, a private dining room, or a banquet hall — confirm when booking
- Allergies and vegetarians: more inns now accommodate requests made at booking, but bonito dashi is hard to avoid. State clearly in advance if fish stock is also off-limits
4. Classic post-bath drinks
- Milk, coffee milk, fruit milk: hand on hip, drink in one go. Bottles in the communal-bath fridge, ¥150–200
- Local sodas: Arima cider, Otaru cider, ramune
- Local sake: Niigata (tasting at Ponshukan inside Echigo-Yuzawa station), Yamagata, Akita, Ishikawa
- Beer after the bath speeds dehydration. Drink a glass of water first
5. Day-trip models that include the food
Kinosaki: two sotoyu at midday → crab set lunch by the station (reserve in winter) → head home. Beppu: Takegawara bath → hell-steamed lunch in Kannawa → Kannawa steam bath. Arima: Kin-no-yu → carbonated-senbei factory → Arima Toys Museum. Each takes half a day.
