One of Japan's oldest black wooden castles, the snow monkeys you've seen in photos, the cool air of the Japan Alps even in summer, and old villages straight out of an Edo-era woodblock print — Nagano is the mountain Japan that many travelers overlook.
If you've done Japan a few times and the big cities are starting to blur, honestly — Nagano is the answer. This is the 'Roof of Japan', a mountain prefecture with an original 400-year-old black wooden castle (Matsumoto), snow monkeys soaking in hot springs while you photograph them (Jigokudani), an alpine valley that stays cool even in August (Kamikochi), and Edo-era post towns you can still walk through (Tsumago). Nagano city is just 90 minutes from Tokyo by Shinkansen.

Nagano (長野) is a landlocked mountain prefecture in the Chubu region, nicknamed the 'Roof of Japan' for the Japan Alps that run through it. It hosted the 1998 Winter Olympics, and its strengths are mountain nature, hot springs, an original black wooden castle and deep-rooted tradition.
Nagano city is about 90 minutes from Tokyo on the Hokuriku Shinkansen, while Matsumoto is easily reached from Shinjuku on the Azusa limited express. Sights are far apart and mountainous, so choose a base that matches what you want to see and allow plenty of travel time.
