Before you travel
Prior reservations are required. Use the current calendar and registration window, and follow the specified campus entrance and parking instructions; ordinary daytime visiting arrangements do not book a star party.
Local time zone: Asia/Tokyo.
Use the official source for directions and the permitted observing area. An exact observing point is not verified here.
Make a private plan for your chosen observing spotNAOJ's Mitaka public stargazing programme shows that a research institution can offer a structured urban astronomy visit. The current calendar and FAQ are more useful than assuming a regular monthly pattern remains unchanged.
Check the application period, capacity and reception group for the actual event. Read the specified entrance and parking instructions, since moving through a campus at night can differ from a daytime visit. Ask about language and accessibility needs in advance. A forecast can explain likely sky conditions, but it does not reserve a place or replace the organiser's decision about how the programme runs.
