The Toyama Kitokito Airport is located around 7 kilometers from central Toyama City, and provides domestic flights to and from Tokyo and Sapporo alongside international routes to Seoul in South Korea, Shanghai in China, and Taipei in Taiwan. The airport is spread out over four floors, with the first floor for check-ins and arrivals, the second floor for departures, and the third and fourth floors consisting of observation decks.
There are several different restaurants and cafes at the airport, including a sushi restaurant with fresh seafood from Toyama Bay, and the Wing Cafe which serves up a range of more western inspired fare such as hot dogs, baguette sandwiches, and pancakes. You'll also find a handful of retail stores including the Toyama Airport Shop which offers various locally produced items, including sake, seafood, confectionery, and rice.
One quirky thing you may notice at the airport's water fountains are the signs mentioning how delicious the local water is. This is because it's ultra-pure snow melt water from the surrounding mountains - and you can truly taste the difference!
If you plan to rent a car to further your travels in the area, there are car rental counters by the first floor arrivals area.
The good news is that water quality regulation in Japan is very good, barring storm damage.
