Cosmo Planetarium Shibuya

Finding stars inside the dome

Cosmo Planetarium puts 120 reclining seats beneath a 17m dome on Owada's 12F; 36 seats also rotate through 90 degrees. Its GeminiStar III combines optical stars with digital space imagery. In a February 2026 interview, presenter Sasaki described adding travel photographs and astronomy stories to live narration; presenters vary by date.

For a child’s first visit, compare the length and story of family sessions. For a longer astronomy explanation, look at the general programme’s subject. Japanese live narration forms part of the experience; enquire first if English narration is essential.

Family costs and reaching 12F

Admission is ¥800 adult and ¥400 for primary/junior-high pupils: ¥1,200 for one adult and one primary-school child. One preschooler on each adult's lap is free; a separate seat requires a ticket. Seating is unreserved. The operator distinguishes web and local-machine allocations, and the 12F machine sells same-day tickets; the on-site report confirms electronic-money payment.

Use 23-21 Sakuragaokacho. Current operator directions give a five-minute walk from Shibuya's JR New South Gate/Sakura Stage side or subway Exit A5, followed by the lift to 12F. Hours are 12:00–20:00 Tuesday–Friday, 10:00–20:00 weekends/holidays. Mondays close, or the following weekday after a Monday holiday. Free hands-on Hachilab on 3F offers a different activity before or after a timed show.
