Japan gets a rare five-day holiday this September, with “Silver Week” running from Saturday, September 19, through Wednesday, September 23!
For everyone planning to be here in the Kofu basin, we’ve rounded up the best events, outings and activities to give you some ideas of things to do over this special week✨
◾Shosenkyo Gorge
Recognized as a Japan Heritage site and known as Japan's most beautiful gorge, Shosenkyo is particularly famous for its gorgeous fall colors, but presents as many stunning facets as there are seasons, making it an ideal repeat destination.
As warm temperatures linger in the basin, escape to the valley for a refreshing stroll along the babbling water and towering cliff faces.
*The summit of Mt. Rakanji—the highest peak in Shosenkyo—is part of the 2026 Central Yamanashi Hiking Campaign! See previous post for more details.
◾Mt. Yumura – Mt. Hachioji – Mt. Tengu hiking trail
This route takes you from Mt. Yumura—home to a reproduction of a beacon tower from the Warring States period—to Mt. Hachioji and its panoramic views of the Kofu Basin, and finally to Mt. Tengu, home to the largest stone-piled burial mound in Yamanashi Prefecture.
*The summit of Mt. Yumura is part of the 2026 Central Yamanashi Hiking Campaign! See previous post for more details.
⏰Time: About 3 hours and 30 min.
*The trailhead is located behind the Midorigaoka Sports Park Gymnasium.
◾Grape picking
Known as the "Fruit Kingdom of Japan", Yamanashi is the country’s biggest producer of grapes, making grape-picking an especially popular pastime in summer going into the fall 🍇
Visit one of the many orchards opened for grape picking, and enjoy peering up at the beautiful clusters hanging from the trellised vines as you compare and savour all their unique characteristics!
*Note that Hayakawa-en in Kofu is now closed for grape picking for 2026 ⚠️
But other places are still accepting visitors until mid to late November; visit Jalan to find and make a reservation for other grape-picking orchards in Yamanashi: https://www.jalan.net/kankou/150000/g2_I8/
