By August, most of Japan sees outdoor activities grinding to a halt as everyone waits for autumn to arrive with its relief from the summer sun. Here in Matsumoto, however, our relatively cooler climate means there’s still plenty to do!

Matsumoto City Museum Nighttime Opening
For three nights in August, and an additional two nights in September, the Matsumoto City Museum will be opening its doors later in the evening, perfect for those who want to spend the day exploring the city in the daylight, and want to continue exploring after hours. The café and the shop on the first floor will also be open for this event. As well as the permanent exhibit dedicated to Matsumoto (3F), the special exhibit (2F) will also be open for the event. This time, the special exhibit is dedicated to Momoko Sakura, a manga artist best known for her long running work, Chibi Maruko-chan, which ran from 1986 until 2022, 4 years after Sakura’s death. The series was so popular that it inspired two anime series by the same name, one of which ran from 1990 to 1992, and the other which started in 1995 and is still running today. A must see for manga and anime lovers!

Naraijuku Post-Town Walking Tour
Narai-juku is a traditional post town on the ancient Nakasendo trail, a walking path that once connected Kyoto to Edo (modern day Tokyo). As the center point of the trail, Narai was especially large, and became known as “Narai of 1,000 houses.” The post town was designated as an Important Preservation District for Groups of Important Buildings, leading to it being incredibly well preserved not as a tourist-focused destination, but as a traditional town that still functions today much as it did hundreds of years ago. To truly engage with the history of Narai and soak up the culture and atmosphere, we recommend booking a guided walking tour of the area.
