Ikaho Onsen
An ancient resort town built up a single stone staircase of 365 steps — each step flanked by traditional wooden inns, souvenir shops, and bathhouses. The brown iron-rich water (chakki-yu) has been praised since the Manyoshu (8th century) and stains baths and tiles a distinct dark orange. The town was a favourite retreat of writers and artists throughout the Meiji era.

Local Tips
The 365-step stone staircase (Ikaho Stone Steps) lined with ryokan and souvenir shops is the town's defining feature — one step for each day of the year. The brown (iron-rich) spring and clear spring give very different baths; try both if time allows. Ikaho is an easy day trip from Tokyo (2 hours by Shinkansen + bus or limited express).

Kusatsu Onsen
Japan's most celebrated hot spring resort — producing over 32,000 litres of acidic sulphurous water per minute from its collective springs, centred on the iconic Yubatake (hot water field). The water is so acidic (pH 2.1) that it kills almost all bacteria, giving rise to the local saying "the only thing Kusatsu water can't cure is a broken heart." The Yubatake at night is extraordinary.

Lake Haruna
A caldera lake at 1,084 metres on the volcano Mt Haruna. The lake is famous for its winter ice fishing (smelt) when the surface freezes solid enough to walk on, its summer wakasagi fishing from boats, and the horse-drawn sleighs that cross the frozen surface in February.

Minakami — Outdoor Sports Capital
The Tone River gorge town that is Japan's outdoor sports capital — white-water rafting, bungee jumping, canyoning, and hot air ballooning all operate year-round. Minakami is also the gateway to the Tanigawa mountain range (the Japanese Alps' most lethal peak) and to Tanigawadake Onsen, a cable car onsen above the snowline.
