Todoroki Gorge

In Takaki in Isahaya City in Nagasaki Prefecture, Todoroki Gorge rises from Mount Tara as a clear stream where thirty waterfalls large and small follow one after another. It has been chosen among the one hundred famous waters of Japan by the Ministry of the Environment, and the surrounding forest is also listed among the one hundred forests of headwaters. Wrapped in clear water and rich greenery, it is a healing nature spot full of fresh air.

The standout is Todoroki Falls, whose roar echoes in a wide basin with great force. The path is well kept, letting you come right up to the falls. Other falls of differing character are scattered along the stream, such as Senryu Falls, Futami Falls, and Yoryu Falls, and fireflies, sculpin, freshwater crabs, and yamame trout live here, as only a clear stream allows.

Enjoying the Seasons

In early summer fireflies dance, and in summer you can enjoy the cool stream and flowing somen noodles. Autumn brings splendid colored leaves across the gorge, and the fresh green season soothes the heart with vivid greenery. The stream holds a nearly constant water temperature year round, staying cool even at the height of summer. It is a place to feel the blessings of water and greenery all year round.

Access and Basic Information

• Location: Zenjuji, Takaki, Isahaya City, Nagasaki Prefecture
• Access: About fifteen minutes by taxi from Yue Station on the JR Nagasaki Main Line, or about forty to forty five minutes by car from the Isahaya interchange on the Nagasaki Expressway
• Campgrounds and a flowing somen teahouse are nearby
• Free to view, no admission fee, though facilities such as the somen restaurant charge separately
• Trails and facilities may close during heavy rain or high water, so check the official Isahaya City website in advance

Practical Travel Notes

• Best season and time: The highlights are early summer nights when fireflies dance, summer when the flowing somen draws crowds, and autumn colors. The streamside stays cool even by day, so it also suits a midsummer escape from the heat.
• Avoiding crowds: The somen hours during summer holidays and Obon fill with families. For a quiet walk in the gorge, weekdays or early mornings are best.
• Time needed: About thirty minutes for a stroll around Todoroki Falls, or one to two hours to reach the upstream falls.
• Nearby real spots: Close to a trailhead for Mount Tara, it pairs well with a hike. Combining it with Isahaya Park and its spectacles bridge in the city, or a drive along the Ariake Sea, is also fine.
• Budget feel: Viewing is free. The somen restaurant and campground charge separately. Since most visitors come by car, allow for a rental car and fuel.

A Quick Tip

The streamside is wet and slippery, so wear non slip shoes. If you walk to the upstream falls, dress for easy walking. The waterside is chilly even in summer, so bring an extra layer. When the water is high, do not push on, and check trail conditions before you visit.
