If you’re feeling tired, why not relax and take a nap under a sky full of stars at the planetarium? For Labor Thanksgiving Day, enjoy a peaceful star viewing session with minimal narration, soothing background music, and gentle aromatherapy to help you drift into restful sleep. Reservations are required—please purchase tickets in advance through the Tsukuba Expo Center website. Open to junior high school students and older who can enjoy the event quietly.
