Agatsuma

Agatsuma District is excellent year-round, but December to March is best for snowy onsen scenery and skiing near Kusatsu. April to June and October to November are comfortable for walking, scenic drives, and ryokan stays, while summer is cooler than Tokyo due to the highland setting.

From Tokyo, take the JR limited express or Shinkansen route toward Takasaki, then connect by train and bus to Kusatsu Onsen or Nakanojo. Highway buses also run from Tokyo to Kusatsu, and rental cars are useful for visiting multiple onsen towns and rural attractions.

Kusatsu Onsen is walkable once you arrive, especially around Yubatake, Sainokawara Park, and the ryokan area. Buses connect major towns, but a rental car is the most flexible option for Shima Onsen, waterfalls, viewpoints, and multi-stop rural routes.

Kusatsu Onsen is the best area for first-time visitors who want famous baths, Yubatake views, restaurants, and a lively onsen-town atmosphere. Shima Onsen is quieter and better for riverside ryokan stays, nature, and a slower retreat. Nakanojo is practical for transport links and local sightseeing, while highland lodges suit travelers focused on skiing or hiking.
