French Restaurant Ruisseau is a quaint restaurant of a 90-year-old renovated Japanese traditional house in a quiet country area in Ogawa Village. At this restaurant, you can have authentic course dishes made from seasonal vegetables and fresh meat made in Nagano. Lunch operation is only on weekends and holidays, while reservation-only dinner is available on weekdays as well. You can make a reservation a month before your dinner date, but it is recommended to make it at least 2 weeks before due to its busyness.
