The Kinugawa River has carved a steep, wooded gorge through the hills south of Nikko, and the best way to see it is from the water. The traditional river ride known as Kinugawa Line Kudari, where kudari means going downstream, takes passengers about forty minutes through the valley in a long flat-bottomed wooden boat steered by boatmen. The pace is easy. The boats drift with the current, with moments of gentle white water where the river speeds up, and the boatmen keep up a running commentary in Japanese, with the rock formations and wildlife pointed out as you pass. There is no real danger and no special skill required, and the ride suits ages from small children to grandparents. It is a pleasant seasonal outing that fits neatly into a Kinugawa Onsen stay, and it feels refreshingly old-fashioned next to the theme parks nearby.
The scenery is the draw. Steep banks of cedar and broadleaf trees rise from the water, and the cliffs in places are bare rock, folded and fractured in layers. In spring there are wild cherry blossoms and azaleas along the banks. In summer the river is cool and green, with fish visible in the shallows and the call of kingfishers. In autumn the slopes turn red and gold, and this is the season most visitors choose, though the boats are busier then. A passing shower softens the colours, though you will want a waterproof layer.
What to expect on the day
You arrive at the boarding point a little ahead of departure, board with a small group, and sit on benches along the sides of the boat. Life jackets are provided and you wear them for the whole trip. The boat is open, so dress for the weather and bring a layer, because the river air can be cooler than the road.
Photography is easy from your seat, though you will want a secure grip on your phone. Operating hours run from morning until mid-afternoon, with the last boats leaving a little before the end of the day, and you should reserve or check availability ahead of weekends and holidays, as the boats fill in autumn.
The season matters. The business runs through the warmer part of the year and closes in the cold months, from late November until early April, so a winter visit will not include it. If you are staying in Kinugawa Onsen in winter, you will want a different activity, such as a soak in a hot spring or a visit to Edo Wonderland. Check the schedule before you plan, because water levels and weather can also affect operations.
Getting there requires a bit of planning. The boarding point is a short distance from Kinugawa Onsen, and a taxi or a bus is the usual way to reach it. Ask your hotel or the local tourist information desk how to get there and how the return works, since the boats finish downstream.
The ride pairs well with a hot-spring night, and with a half day at Tobu World Square or Edo Wonderland. It is a gentle introduction to the Kinugawa side of Nikko, and one of the nicest ways to spend an hour outdoors in autumn.
