The primary transportation hub of Karuizawa is Karuizawa Station, which is served by the JR Hokuriku Shinkansen, Shinano Railways, local buses and highway buses. While some of the town's sights can be reached on foot from the station, others are distributed quite far across a relatively wide area and are best reached by bus, taxi, rental car or bicycle. A secondary transport hub is Naka-Karuizawa Station, one station west of Karuizawa Station by the Shinano Railways.
The local bus network is operated by two companies, Kusakaru Kotsu and Seibu, and connects Karuizawa Station to the various attractions around town and beyond:
The most important lines are the hourly buses by Kusakaru Kotsu from Karuizawa Station via the Kyu-Karuizawa Ginza (160 yen, 5 minutes), the former Mikasa Hotel (270 yen, 10 minutes) and the Shiraito Waterfall (710 yen, 25 minutes) in direction of Kusatsu Onsen and by Seibu from Karuizawa Station via the Kyu-Karuizawa Ginza (150 yen, 5 minutes) to Naka-Karuizawa (290 yen, 15 minutes). While many of the Seibu buses terminate at Karuizawa Eigyosho, a few of them continue to the Onioshidashi Park (1210 yen, 35 minutes) and further to Manza Onsen.
In addition, there are a few loop bus lines that connect the stations with several attractions around town as well as a shuttle bus between Karuizawa Station and the Kyu-Karuizawa Ginza. The Karuizawa Free Pass allows unlimited rides on the above-mentioned buses (but not beyond Onioshidashi bus stop) plus rides on the Shinano Railways between Karuizawa Station and Komoro Station. A 1-day pass costs 2500 yen while a 2-day pass is available for 3600 yen.
Karuizawa is also suitable for exploration by bicycle. Many rental shops can be found close to Karuizawa Station and the Karuizawa Ginza area. Rental fees are around 500 yen per hour or around 1000 yen day, while electric bicycles are avaiable for a little bit more. Another alternative is to travel by rental car.
