Tokyo Dome City
While Tokyo Dome City in Suidobashi is famed for its amusement park, it’s also home to the TeNQ Space Museum and Spa LaQua, both of which are ideal rainy day destinations. The TeNQ Space Museum is divided into nine areas, with fascinating exhibits that allow you to discover the universe beyond planet Earth
If you’re after a more relaxing experience, head to Spa LaQua, which draws on natural spring water that rises from 1,700 meters below. It’s divided into two areas - the Spa Zone hot spring area and the Healing Baden Zone with its low-temperature saunas - and is an excellent opportunity to experience Japan’s unique bathing culture while soaking up incredible Tokyo views.
