There are no supply of amenities in the NOMYC except shampoo and soap in the bathroom. Do bring your own towels, tooth brushes, tooth paste, etc.
Because the NOMYC is surrounded by greens, you may be annoyed by mosquitos and other insects. You may want to bring insect repellant and anti-itch ointment, although the organizer also prepares some.

Those teams who comes to Japan on July 8 (or July 7) will be accommodated in the NOMYC. On July 9, the adult participants move to the Nippon Seinenkan Hotel.
<Late Departures>
We ask all adult participants to check out the Nippon Seinenkan Hotel in the morning of July 17 (Mon) and go to the Closing Ceremony at the NOMYC. Those who stay for the night of July 17 (and possibly for the night of July 18 also) will be accommodated in the NOMYC. Any adjustment of room charges (i.e. surcharges for single occupancy) associated with this arrangement will be settled at the Registration Desk. We apologize for inconvenience and appreciate your kind understanding.

There is no dress code in IPhO2023. Tokyo in mid July is generally hot and humid. The daytime temperature can be anywhere between 30 to 35 Celsius. The rainy season may or may not be over by mid July, so there is a chance of occasional rain.

Some may feel freezing in some of the air-conditioned rooms. It is advisable to bring something to wear in order to adjust to the room temperature.

Bring a pair of comfortable shoes for excursions and other activities. Those who suffer motion sickness should bring an appropriate medication, especially for the one-day excursions with long bus ride.

You are recommended to bring a folding umbrella or a compact rain wear in preparation of occasional rain

The electricity in Japan is 100 volts and 50 Hz (in Tokyo area). The power plug sockets are type A. Make sure to bring a suitable power adapter.

Tap water in Japan is safe to drink. Coin-operated beverage vender machines are everywhere.

Since May, the COVID-19 has been down-categorized as common infectious disease. Accordingly, there is no special border measures concerning COVID-19. Infection prevention measures such as wearing of a mask are left to the individual personal discretion.
Still, we have to exercise due precaution to prevent infections. The organizer will prepare antibody test kits in stock for quick check. If you notice changes in your physical condition, do notify the staff of IPhO2023 organizer and visit nurse station. 

International Board Meeting
The International Board Meetings will be held in the meeting rooms on the 8th floor of the Nippon Seinenkan Hotel. The main meeting room (Room Yellow) is for leaders only. Observers can watch the monitor screen in another meeting room (Room Blue), or on-line broadcast from the hotel rooms. In the latter case, the TV set in the hotel room can be used as external display for your PC. If you want to utilize it, bring an HDMI cable.
The OlyExams Tool will be used for discussions, voting, translating, marking and managing exams. We trust the leaders are already familiarized with the operation of the OlyExams Tool by doing the trial work of translating the General Instructions.
Access to the OlyExams system will be via a WiFi network. Leaders and observers are expected to bring their own personal computers. Make sure to bring your international power adaptor. The power outlet in the meeting room is 100 volts and the power plug socket is type A.
