Komatsu Airport (小松空港, IATA: KMQ)  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  services leave for JR Komatsu station every 20-30 minutes (12 min, ¥260). Hokutetsu  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  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.
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.
Those looking for souvenirs might find a better selection in Kanazawa, especially in Kanazawa station or near Kenrokuen. The Komatsu Urara Concert Hall (near the station) offers some souvenirs in its gift shop, including items bearing Kabukki, the Komatsu mascot.
Komatsu city houses several kutani-yaki studios, including the workshop of one Living National Treasure. You can buy some kutani-yaki pottery in the station and at the Urara, or you can visit some of the art dealerships scattered throughout the city.
A great place to eat a steak lunch or dinner. They cook the steak in front of your eyes and serve many delicious side items with the steak. Side items include vegetables, salad, rice, and miso soup. You'll also get ice cream for desert with your choice of tea or coffee. Lunch starts at 11:30 and 100 grams of steak with all of the side dishes costs 1800 yen. You can get a larger portion of steak if you wish, but it will cost more money.
Doihara-machi 516 (South of Komatsu Station, across from the Hokuriku Bank)
This izakaya (Japanese style pub) has relatively inexpensive beer and focuses entirely on local, seasonal cuisine. The atmosphere is quirky and boisterous--expect seasonal decorations that verge on tacky, loud groups, and some cigarette smoke. While not a refined atmosphere, the food is meticulously prepared and always delicious. This is a great place to try Ishikawa's famous seafood, both in sashimi and broiled form. Yaemon also has the best vegetarian selection of Komatsu's izakayas. English menues are available, and small plates cost between 400 and 800 yen.
Aperetif Wine Bar
Across from the station and a little south, past the "Miss World" Club
This cozy wine bar offers one the best happy hours in Ishikawa--half off any drink between 6 and 8 pm. The bar master is friendly and enjoys practicing his English with customers. Wine selections come from Chile, Spain, France, and California, and are all solid. You can also custom-order cocktails and try umeshuu (plum liquor) or Nihon-shuu (Japanese liquor made from wheat, sweet potatoes, or whatever else ferments). Before the happy hour discount, drinks cost about 500-600 yen.
