Oct–Nov1h 6m from Tokyo Station, ¥6,130 reserved. Forest roads, a pond that turns red in late October, an onsen at Hoshino and the earliest ski opening in Nagano.
Karuizawa is 1h 6m from Tokyo on the fastest Asama, ¥6,130 reserved, and is the first stop on the Hokuriku Shinkansen after the Tokyo suburbs. A day covers Old Karuizawa Ginza and Kumoba Pond, or Hoshino with a ¥1,350 onsen. The ski resort opens on 31 October 2026, and colour at Kumoba Pond peaks from mid-October to early November.
Karuizawa (軽井沢) sits at about 1,000 m on the slopes of Mt Asama. It was a post town on the Nakasendō, and became a summer resort after the Canadian missionary Alexander Croft Shaw built a house here in 1886. Today it splits into three parts: Old Karuizawa (Kyu-Karuizawa) with the Ginza street and Kumoba Pond, the station area with the Prince Shopping Plaza, and Naka-Karuizawa, where the Hoshino resort sits 4 km west of Old Karuizawa. It is also the first stop on the Hokuriku Shinkansen, so you can start a trip to Nagano and Kanazawa here or end one on the way back.
Karuizawa Ginza is a street of bakeries, jam shops, cafes and western goods, anchored by the small Shaw Memorial Chapel (1895). Kumoba Pond (雲場池) is a loop of about 20 minutes, best for colour from mid-October to early November. The Former Mikasa Hotel (旧三笠ホテル) has reopened as a museum with a cafe, ¥1,000.
A curtain of spring water about 70 m wide falling over a rock ledge, cool all year. Allow 30 to 40 minutes for the paths. It is lit in winter. The Kusakaru bus to Kusatsu stops here, which is why it fits a day that continues to Kusatsu.
Harunire Terrace (ハルニレテラス) is a row of wooden-fronted shops and restaurants under elm trees; shops run about 10:00 to 18:00 and restaurants later. Hoshino Onsen Tombo-no-yu (トンボの湯) is open 10:00 to 22:00 (last entry 21:15): adults ¥1,350, children ¥800, and ¥1,550 and ¥1,050 in Golden Week, August and the New Year. The Stone Church (石の教会) is free, about 10:00 to 17:00, and closes for weddings.
An open-air outlet village of more than 200 shops set among lawns and a pond, a few minutes from the ticket gates. It is the practical stop on the way home. Hours change by season and day, so check the Prince Shopping Plaza site on the day.
An observation platform on the old Usui Pass road with views of Mt Asama and the Karuizawa basin. It pairs with Kumoba Pond; go by taxi or car rather than counting on a bus.
Karuizawa is the easiest place on the Hokuriku line to see by bicycle. Rentals run about ¥500 an hour or ¥1,000 to ¥1,500 a day. Old Karuizawa is a flat run from the station, and Naka-Karuizawa is farther: 4 km west. The walk from the station to the Former Mikasa Hotel is just under an hour.
