When you feel like you need to take a breather from the rigors of sightseeing, unwind in the sun at Lake Kuttari. Bring some nibbles and a good book ... Whatever helps you unwind!
You're spoiled for sightseeing choice in Shintoku. Lake Kuttari is a great place to kick off here, but there are plenty of other interesting sights to check out. Sahororizoto Ski Area, Sahoro Country Club, and Karikachi Kogen Eco Torokko are near the body of water and will round out your day nicely.
