You can go round the lake in about 30 minutes by car. There are some unique museums including Kitazawa Museum of Art. And, why not try sake tasting at the shop of Miyasaka Jozo Brewery, which is famous for the “Masumi” brand of sake? Lake Suwa is also famous for fireworks in summer.
An amphibious bus tour around Lake Suwa started in May 2009. A bus which runs on land enters the water without modification, which is quite an experience for the passengers! The scheduled operation is from April to January. (Nihon Suiriku Kanko, 0266-75-2650)
