“Roppongi Tenmon (Astronomy) Club” is a generic name for the series of astronomy-related events held at the Roppongi Hills observation deck, Tokyo City View, and astronomy seminars/workshops with experts.

As “Roppongi Tenmon Club” is not a special membership organization, anyone can participate in any events throughout the year, making it ideal for people on their way home from work, dating couples, and families with children looking for some casual enjoyment.

In 2025, regular events will be held on the fourth Friday of each month, including “Starlight Talks” (mainly at online), as well as irregular stargazing sessions on days when the moon is visible.
Come along and enjoy some stargazing with the experts at “Roppongi Tenmon Club”?
