How to Get to Karuizawa

Karuizawa is easiest to reach by shinkansen: the Hokuriku Shinkansen stops at Karuizawa Station and gives a fast connection from Tokyo. For budget travelers, highway buses from Tokyo and surrounding hubs are a reliable, cheaper option.

By Air

Narita International Airport (NRT): From Narita take the Narita Express (N’EX) or Keisei Skyliner to Tokyo stations (approx 55-90 minutes, N’EX around ¥3,000-3,200 to Tokyo). From Tokyo Station catch the Hokuriku Shinkansen (Asama) direct to Karuizawa (about 1 hour 10 minutes, see shinkansen fares below).

Haneda Airport (HND): Haneda is closer to central Tokyo. From Haneda take the Keikyu Line or an airport limousine bus to Tokyo Station or Shinjuku (30-60 minutes, fares roughly ¥300-1,200), then transfer to the Hokuriku Shinkansen bound for Karuizawa.

By Train & Bus

Train: Karuizawa Station is on the Hokuriku Shinkansen (Asama services) between Tokyo and Nagano. Travel time from Tokyo Station is about 1 h 10-15 min; one-way fares are typically in the ¥5,000-¥6,500 range depending on seat/reservation. Local JR lines and buses serve nearby resorts and the station.

Bus: Highway (express) buses run from Shinjuku and other Tokyo terminals to Karuizawa. Journey time is around 2.5-4 hours depending on traffic and the route; fares commonly range from about ¥2,500-¥4,000 one-way. Buses are a good lower-cost alternative and can be direct from major Tokyo terminals.
