2026 Starry Sky Full-Day Course at Hamagin Kodomo Space Science Museum (Yokohama Children's Science Museum)

This is a day to fully enjoy space and starry skies at the Hamagin Kodomo Space Science Museum (Yokohama Children's Science Museum) in Yokodai, Isogo Ward, Yokohama. The whole building is designed as a hands-on science museum modeled on a giant spaceship, capped off with a sky full of stars in the planetarium. It is open 9:30-17:00 (last admission 16:00), and closed on the first and third Tuesdays each month and over the New Year holidays (temporary closures may also occur). Admission is 400 yen for adults and 200 yen for elementary/junior high school students (free for elementary, junior high, and high school students every Saturday); the planetarium costs 600 yen for adults, 300 yen for elementary/junior high school students, and 300 yen for ages 4 and up (free for ages 3 and under, though a fee applies if a seat is used). Parking is also available. In the early afternoon, get active at the adjoining Yokodai Station Square Park, take a breather at the Kodomo Log House, and then spend a good long while at the science museum in the afternoon. It is a rain-proof starry sky course where you can encounter a sky full of stars right in the middle of the city.
