Rules in force · 5
- East Asia ↗Every border in East Asia is a full international border, Hong Kong and Macau included: an entry permission for one never covers the next.
- East Asia ↗Ferries between Korea, Japan and China cancel in rough seas and typhoons; keep a flight or a spare day behind every sea leg.
- Japan ↗IC cards (ICOCA/Suica) are topped up with cash at station machines.
- Japan ↗Smoking while walking is banned in most city centres; use designated areas.
- Japan ↗Shinkansen bags 160–250 cm (L+W+H) need a seat reserved with the oversized-baggage area.
Karuizawa sits at about 1,000 m in eastern Nagano and runs roughly 5°C cooler than Tokyo in summer, which is why it became a resort town in the late 1800s and still fills with second homes, cafés and boutiques. The Shinkansen from Tokyo takes about 70 minutes, so it works as one night on the way to Nagano or as a long day trip. Sights are spread out along a valley: the station and outlet mall at one end, Old Karuizawa and the churches in the middle, waterfalls and onsen to the north and west.

Arrive & move
Airports are listed under At a glance; this is how to move once you are in
Getting around
The town is a long strip, not a walkable grid. Buses (Kusakaru Kotsu and Seibu Kanko) run from Karuizawa Station to Old Karuizawa, Hoshino and Shiraito Falls; taxis are easy to find at the station but thin elsewhere. The Shinano line links Karuizawa and Naka-Karuizawa. A car or taxi is the practical way to reach the falls and Mount Asama trailheads.
