$8–$10 gets you a fast bowl of udon here.
Kineya Mugimaru in T1 runs as a basic self-service udon counter, the kind you see all over Japan but rarely at airports. It sits landside in Terminal 1, so this works best before check-in or if you’re greeting someone and want a quick bite. Prices sit firmly in the budget tier, with most bowls in the ¥700–¥1,000 range, which is cheap by airport standards.
Expect the standard Kineya lineup: hot kitsune udon with sweet fried tofu, tempura udon, and simple kake udon, plus a few rice sides like onigiri. Portion sizes lean toward regular Japanese shop portions, not oversized airport bowls, so a combo of udon plus one side usually lands just under ¥1,200. Service style is cafeteria: order at the counter, pick up your tray, and bus it yourself.
The shop keeps typical airport daytime hours, roughly breakfast through evening departures in T1, so you can use it for a 9:00 a.m. bowl or a 6:00 p.m. pre-flight carb load. Seating is counter-style with a few small tables, fine for solo diners or pairs but not great for larger groups trying to spread out. Turnover is quick, so even if every seat is taken, most people clear out in 10–15 minutes.
Since there’s no standout signature hype for this location, treat it as a “get in, eat, go” stop when you want something familiar and cheap near T1 check-in. If you like a bit of crunch, add one or two à la carte tempura pieces; they usually run around ¥120–¥200 each and fill out the meal without breaking the airport budget.
Tip: if you have a tight departure from T1, budget 20–25 minutes total here from joining the queue to slurping the last noodles and heading toward security.
