This day centers on 'Cosmo Theater' (コスモシアター) inside the Matsuyama City General Community Center (松山市総合コミュニティセンター) in Matsuyama City, Ehime Prefecture. Attached to Shikoku's largest planetarium with a 23m-diameter dome, it holds monthly stargazing sessions using an astronomical telescope (e.g. 'Let's See the Mid-Autumn Harvest Moon'). Since the date/time and whether reservations are required are announced session by session on the official website, please be sure to check before visiting. Parking is limited. During the day, you can also enjoy sightseeing in central Matsuyama, including Dogo Onsen and Okaido Shopping Street.
