The space telescope TESS was launched last year to conduct an extensive survey of exoplanets orbiting nearby bright stars, which will be followed by precise measurements with CHEOPS launched this autumn. Furthermore, spectroscopic observations of those transiting planets will be extensively conducted by scheduled missions such as JWST, ARIEL, and WSO-UV. We are about to enter the age of characterization of exoplanet atmospheres, which is a crucial milestone also in habitable planet science. Also recent solar-system missions have brought much new knowledge of the solar-system planets and small bodies. Against this background, we will hold a symposium that brings together scientists from a broad range of research topics such as planetary atmospheres, habitability, and planet formation and evolution, aiming for the participants to share current understanding regarding such important topics for the extra-solar and solar-system planets. We hope that you will actively join this exciting symposium and look forward very much to seeing you in Okinawa.

Location and Access


The conference will be held at the Bankoku Shinryokan Okinawa Resort Mice Facility in Okinawa, Japan.


By Bus

There are four ways to go to the venue from Naha airport:

Aiport Shuttle Bus (Area D) : It takes about 2 hours, the cost is 2,040 JPY. Taking a bus at the airport bus stop #1 and getting off at the Busena Terrace Hotel. It is about a 3-minute walk to the hotel.

Okinawa Airport Shuttle : It takes about 2 hours, the cost is 1,600 JPY. Taking a bus at the airport and getting off at the Kariyushi Beach Mae. It is an 15-minite walk to the hotel.

Local Bus (Number 120) : It takes about 2.5 hours and the cost is 1,720 JPY. Taking a bus at the airport bus stop #3 and getting off at the Busena Resort Mae. It is an 15-minute walk to the hotel. A timetable is here.

Hotel Shuttle bus : There is a complimentary shuttle bus between the Naha Terrace and the Busena Terrace (Venue). Between Naha airport and Naha Terrace, it is about 20 - 30 minutes by taxi.
Reservations must be placed by 22:00 of the previous day.

By Taxi

The distance from Naha airport to the hotel is about 60 km, the fare is about 16,000 JPY. A duration is about 75 - 90 minutes.


The hotel Busena Terrace offers special rates for participants to this conference. Please make a reservation here . The following prices include daily breakfast, service charge, and government tax.

Room type Number of Guests Price per room per night
Standard room with Gardenview One 24,200 JPY
Two 24,200 JPY
Three 29,700 JPY
Standard room with Oceanview One 28,600 JPY
Two 28,600 JPY
Three 36,300 JPY

Just for your information, there are some relatively cheaper hotels around the venue. From those hotels, however, it will take at least 20 minutes to walk to the venue.


The conference banquet will take place on Thursday 17th October at Ocean Hall in the conference hotel.
The cost of the dinner is 5,000 JPY per person.


There will be no talks on the afternoon of Wednesday 16th. We will organize a trip to Nakijin Castle Ruins (World Heritage) and Kouri Island.
The prepayment fee of the excursion is 3,000 JPY (includes the cost of the bus, admission fees for each place).

Route and timetable

If it rains, we will go to Okinawa Churaumi Aquarium , instead of Nakijin Castle Ruins and Kouri Island.

13:30 Departure from the conference hotel
14:15 - 15:15 Biseno Fukugi Namiki
15:30 - 16:30 Nakijin Castle Ruins
