A new complex coming to Haneda Airport contains a luxury hotel with a 24-hour rooftop natural hot spring that offers a view of Mount Fuji.

The Haneda Airport Garden, due to open April 21, will provide around-the-clock service to inbound tourists, including those attending the 2020 Tokyo Olympics.

The multi-use complex will house two hotels, retail outlets and a bus terminal where medium- and long-distance buses will offer direct access to cities outside Tokyo.

Sumitomo Realty & Development Co. will operate the complex, which will be directly connected to the airport's international terminal.

The number of flight slots at the transportation hub in Tokyo’s Ota Ward will also be increased to help achieve the government target of accepting 40 million foreign travelers a year in 2020 as part of efforts to make the airport an international hub airport.

The hot spring on the roof of the Villa Fontaine Premier Haneda Airport luxury hotel will be open to all users of the airport.

Four other indoor hot springs and saunas will be available there as well.

All of the hotel's 160 guest rooms will have a river view.

Haneda Airport Garden's other hotel, the Villa Fontaine Grand Haneda Airport, has 1,557 rooms for guests.

The complex includes the Bellesalle Haneda Airport facility, which will contain a hall with a capacity of about 700 and meeting rooms. It also has shopping zones consisting of 90 restaurants and shops that will sell souvenirs and other goods.

Buses at the terminal will be available to take travelers to the Tokyo metropolitan area and locations in Aomori, Niigata, Osaka, Tokushima, Tottori and other prefectures.

About 800 buses are expected to use the terminal daily in the future.
