Add Matsumoto to your Japan itinerary 📝 It’s only 2.5 hours from Tokyo by train and it’s FULL of hidden gems that are worth a day trip, or better yet, an overnight trip from Tokyo 🏯🇯🇵 Matsumoto is one of the main cities in Nagano prefecture and it’s famously known as the gateway to the northern Japanese Alps. This is where you’ll find the Matsumoto Art Museum — the home of Yayoi Kusama’s origin...

Reviews Summary

Okususobana Dam is a rewarding destination for dam enthusiasts and nature lovers, particularly during the autumn foliage season. Visitors appreciate the scenic drive and the opportunity to collect dam cards. However, potential road closures and narrow access roads require careful planning.

"Saturday, early August 2025.
The weather looks good today, so I'm going on a dam-hopping tour in the Nagano area.
Unfortunately, the forest road was closed, so I couldn't get to the dam and couldn't get a dam card.
According to the website, the dam is scheduled to be restored on Wednesday, October 1st of this year (although it may be earlier or later).
I'd like to return during the autumn foliage season when the dams are restored."

"Dam Tour: Nagano-Okususobana Dam. (202405E)
Gravity type concrete dam, height 59 meters, crest length 170 meters. A multipurpose dam built on the Susobana River in the Shinano River system for flood control, water supply, and power generation. The ``beech and skunk cabbage line'' leading up to the dam is a pleasant road with fresh greenery. Don't overlook the entrance to the administration building. If you cross the bridge ahead, you can see a wide view of the bridge and dam. It is an observation area with restrooms. It will be even more spectacular during the autumn leaves season.
Dam card: Currently being distributed at the Susohana Dam Management Office (Second Management Division)."
