By plane
Komatsu Airport å°æ¾ç©ºæ¸¯, IATA: KMQ (http://www.pref.ishikawa....) is the main airport for Ishikawa prefecture. There are international connections from Seoul and Shanghai, and domestic services from Tokyo, Sapporo, Sendai, Fukuoka and Naha Okinawa.
Komatsu Bus (http://www.komatsubus.jp/) services leave for JR Komatsu station every 20-30 minutes 12 min, ¥260. Hokutetsu (http://www.hokutetsu.co.jp/) also runs direct buses to Kanazawa 40-60 min, ¥1100, Fukui 1 hour and Kaga Onsen 25 min, ¥500.
If time permits, there is an interesting and free aircraft museum (http://www.pref.ishikawa....) just opposite the airport, a short walk from the arrivals hall. It houses several exhibits on the history of Japanese aviation, and about a dozen actual small aircraft. The souvenir shop sells some unique souvenirs, largely based on the Sixth Air Group that occupies Komatsu Air Base Komatsu Kichi, which shares the runway with the civilian airport.
By train
Komatsu is on the busy JR Hokuriku Main Line from Osaka to Naoetsu via Fukui, Kanazawa and Toyama, with several normal and express trains every hour. Ordinary trains to Kanazawa take 32 minutes and cost ¥480. Express trains to or from Osaka cost ¥6,710 if you want a seat.
The Hokuriku Shinkansen, currently under construction, is unlikely to reach the city until 2020 or so.
