Local Tips
Minakami is Tokyo's outdoor adventure base (2.5 hours from Shinjuku) — rafting on the Tone River, bungee jumping, canyoning, and skiing all within a small valley. Book activities in advance for weekends, especially rafting in May–June when the snowmelt creates the fastest water. The Takaragawa Onsen outdoor bath (mixed, very large) at the valley head is one of Japan's most famous.

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.

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.
