Based in the hidden gem of Shinshu, Kumeji Gorge, we offer activities that will create lifelong memories. We also operate the Shinshu Fudo Onsen Sagiriso near Kumeji Gorge, where you can refresh yourself in the hot springs after your water activities. Sagiriso serves lamb raised on its own farm, and you can also enjoy special Jingisukan cuisine.
The Kumeji Gorge SUP tour is one of our most popular activities! As the name suggests, this jungle cruise offers a special experience of paddling a SUP while surrounded by nature in a hidden region of Shinshu. You can enter a unique tunnel on your SUP, go under the Kumeji Bridge, a nationally registered tangible cultural property, and soothe yourself in a waterfall. This tour is packed with content you won't find anywhere else. Join us for a once-in-a-lifetime jungle cruise in the hidden region of Shinshu!
At Shinshu Fudo Onsen Sagiriso, which is run by our company, you can enjoy a hot spring bath after SUP! The hot spring water, drawn from the feet of Acala, enshrined at the foot of Fudo Falls, is said to be miraculously effective and to be a medicinal bath for all ailments. You can be sure that a soothing bath at Sagiriso will truly soothe your tired body!
Shinshu-Shinmachi, where Kumeji Gorge is located, is known as the town of Jingisukan! National Route 19 is also known as the Jingisukan Highway, and there are 10 Jingisukan restaurants along it. Sagirisou also serves Jingisukan, and we especially recommend the meat from Suffolk sheep raised on our own ranch. As this is a very precious cut of meat, it may sell out, so reservations are required. If you get hungry after SUP, be sure to come and try Jingisukan at Sagirisou!

Nice to meet you! I'm Hiro, your guide. Water activities can be intimidating, but SUP is an activity that anyone can enjoy, even if it's their first time! I highly recommend trying it at least once, passing through water tunnels and bridges and soothing waterfalls in the special field of the Sai River Dam Lake!
