Numata Castle Ruins & Town
A castle town perched on a mesa above the Tone and Usui Rivers confluence — the flat-topped plateau creates dramatic views of the surrounding valleys. The town was the domain of Sanada Masayuki (the same commander of Ueda Castle) and holds the Kenmachi shopping street of Edo-period earthen-wall merchant buildings.

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.
