For Attendees

Some of the event staff can speak English, but the Regular Stargazing Parties are conducted primarily in Japanese. We appreciate your understanding and cooperation.

To make for an enjoyable Regular Stargazing Party, please read the following beforehand.

1. Before you arrive

Please note the following points before you arrive.

  • Please dress in comfortable clothes and shoes which are easy to walk in. (Please refrain from wearing shoes which light up because the light interferes with the stargazing activities.)

  • The area where the Regular Stargazing Parties are conducted is designated non-smoking.
  • Please do not bring your pets with you. (Service animals are allowed.)

  • At Registration, please present proof of your reservations (an email printed out or displayed on the screen of your cellphone, a post card, etc.) in order to receive your ticket and reference materials (English materials available upon request).
