Karuizawa (軽井沢)

Nagano prefecture is an exciting mix of mountains, hot spring monkeys, and preserved Edo history. At the heart of the Japanese Alps, Nagano is one of the country’s most popular destinations, whether in winter for its snow sports and the much-loved Jigokudani Monkey Park or in the warmer months for discovering the undulating hills on foot. For fantastic Edo architecture, head to the Kiso Valley for a 60-kilometer stretch of quaint wooden buildings that marked the Nakasendo route 200 years ago.
