Tenbo Park at Tokyo's Sunshine City is once again showing its flair for seasonal celebration with a new event focused on Japan’s rainy season. Following on from its sakura-themed spring festival that transformed the observatory into a sky-high cherry blossom garden, the park is now shifting gears to embrace early summer’s signature blooms—hydrangeas and clematis.

Running from June 3rd to July 2nd, the “Tenbo Park Tsuyubiyori” event offers a wide range of activities that make rainy days worth looking forward to. The observation deck’s artificial turf area, Tenbo Hill, will be adorned with flowers of the season, providing a colorful backdrop to a lineup of hands-on workshops and family-friendly programs. From crafting Teru Teru Bozu dolls to rainy season-themed candle making, the park turns the often-dreary tsuyu weather into a time for creativity and connection.

A highlight of the event is “Baby Day,” taking place on June 26th and 27th. These two days are specially designed for families with infants, offering a baby crawling race, commemorative handprint stamps, and even a parenting consultation session with nutritionists and child development counselors. The event blends fun with practical support, creating a thoughtful space for new parents.

All activities are held indoors at the Sunshine 60 Observatory, which means visitors can enjoy them without worrying about sudden downpours or the rising summer heat. With views from 251 meters above sea level, the setting itself is part of the experience, offering an elevated escape from the season’s challenges.
