The festival runs from June 6th to July 5th. Here, you'll see a sea of ​​white hydrangeas blooming on the hillside. In this area of ​​the vast park alone, there are over 15,000 hydrangeas, expected to reach peak bloom in late June. In addition to the white hydrangeas, the park also features beautiful blue hydrangeas native to Japan—the Black Princess Hydrangea and the Ochre Hydrangea.

This exhibition marks the first public display of Katsushika Hokusai's (1760-1849) "Thirty-six Views of Mount Fuji" (c. 1830-1833), a work transferred to the museum from the Inouchi Collection in 2024. One of Hokusai's most famous works—this set of 46 prints—will be exhibited in its entirety.

This fireworks display continues the tradition of the Ryogoku River Opening Fireworks Festival. Its origins can be traced back to the "Ryogoku River Opening" in 1733 (18 AD), making it one of the most renowned and traditional fireworks displays in the Kanto region. After several interruptions, the festival was revived in 1978 (Showa 53) as the "Sumida River Fireworks Festival." The fireworks are mainly divided into two categories: "warimono," which unfolds into a chrysanthemum-shaped spherical display; and "pokamono," where the firework explodes in the air, releasing stars and other fragments. A fireworks competition is held at the first location downstream of Sakura Bridge and upstream of Koto Bridge, with participating companies including those associated with the Ryogoku River Fireworks Festival and those that have achieved excellent results in numerous competitions.

The Torigoe Festival, held annually in June at the Torigoe Shrine, a shrine with approximately 1400 years of history facing Kuramaebashi-dori, takes place on the Sunday of the festival. Starting at 6:30 AM, Tokyo's largest mobile shrine—weighing approximately 4 tons and 1000 kan—is passed between various community associations, parading through neighborhoods where worshippers live, attracting large crowds. Leading the shrine procession are Sarutahiko (tengu), a tebuki dance troupe, and children waving colorful flags. After sunset, the festival begins with the "Torigoe Night Festival," when paper lanterns at the shrine and tall lanterns from various town associations are lit, creating a solemn yet dreamlike atmosphere. At 9 PM, the shrine procession slowly enters the temple, bringing the festival to its climax.
