Why visit
- Ikaho is a hot spring town built on a slope, with a stone staircase as its main street.
- The water is iron-rich and brown, unusual among Japanese hot springs.
- It is reachable from Tokyo by train and bus in about two and a half hours.
Top places and highlights
The stone steps
Three hundred and sixty-five stone steps run up through the town, with inns, shops and a small shrine along them.
The public bathhouse
A town-run bath on the steps gives day visitors a soak without staying the night.
Mount Haruna and Lake Haruna
A short drive or bus ride above the town, with a caldera lake and viewpoints.
Food and drink
- Small shops on the steps sell sweets and croquettes; most inns serve evening meals.
- Restaurant hours are short and village-like, so eat before the evening.
Getting there and around
- Train to Shibukawa, then a bus up to Ikaho.
- By car from Tokyo on the expressway, with a winding final climb.
Where to stay
- Traditional inns line the steps with tatami rooms and dinner included.
- Shibukawa has cheaper business hotels if you only want a bath.
Best time to visit
- Autumn colour on Mount Haruna is the busiest season.
- Winter is quiet with snow on the steps; summer is cool at this altitude.
Practical tips
- Carry a bag for your shoes and valuables; the steps are steep.
- Check the public bath’s closing day and hours before going.
- Treat fares and bath fees as things to reconfirm.
Suggested day-trip outline
- Arrive in the afternoon and walk the steps.
- Take the day-use bath, then stay the night at an inn.
