How to visit us

Access map

By train

Nagano shinkansen bullet train from Tokyo is the most practical way to commute to our direction. The station to get off is Saku-daira (1h20min from Tokyo). A local train Koumi-line will connect to Nakagomi, the station closest to our office (roughly 10mins/5km from Saku-daira). Alternatively, taxi, bus and car rental are available at the Saku-daira station.

By car

Kan-etsu expressway from Tokyo (Starting from Nerima JCT at Kampachi-dori) branching as Joshin-etsu at Fujioka is the fastest route (exit at Saku I.C. or continue through Saku JCT to the new Chubu-odan expressway and exit at Saku-minami I.C.). Other, alternate route is using Chuo expressway and exit at Sutama for route 141. We do not have parking place to offer, but there are a few public coin parkings nearby.
