As a pioneer of dance music festivals, UMF is now held in 27 countries and regions around the world. Over the past 10 events, top DJs and music producers from around the world have continuously attracted audiences with their vibrant and energetic dance music. Attendees can enjoy underground music styles such as techno and tech house, as well as unique musical styles brought by emerging artists from both domestic and international scenes. As an urban music festival accessible within approximately 15 minutes by car from Shibuya, ULTRA JAPAN has consistently attracted audiences with its diverse appeal, including high fashion. In 2026, the festival will celebrate its 11th anniversary.

The Bunkyo Hydrangea Festival, centered around Hakusan Shrine and Hakusan Park in Bunkyo Ward, Tokyo, showcases approximately 3,000 hydrangeas of about 20 varieties. Hydrangeas are one of Japan's most popular flowers, symbolizing the rainy season. Visitors can stroll among the colorful hydrangeas, enjoying their enchanting fragrance and soaking in the atmosphere of historical sites and the old town. The Bunkyo Hydrangea Festival is held annually from early to mid-June and also features special events and stalls selling food, drinks, and local products.

As one of Tokyo's largest fireworks displays, approximately 15,000 fireworks are launched simultaneously from both banks of the river. Highlights include traditional "artistic fireworks" crafted by Japan's top pyrotechnicians, one of Tokyo's largest "15-inch diameter" fireworks, and the grand finale, a massive "Niagara Falls in the Sky" starry sky display. The deafening roar of the fireworks, launched so close to the audience, is also a major highlight of the show. This large-scale fireworks display, launched simultaneously from five locations, boasts improved quality and quantity, promising spectacular opening and closing ceremonies. A fireworks display will also be held in 2026 to commemorate the 50th anniversary of the Itabashi Ward Tourism Association.

Want to enjoy hydrangeas in nature without leaving Tokyo for a weekend getaway? Then head to Wonderful Nature Village next to Tokyo Summerland for the Hydrangea Festival! 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. These varieties are expected to bloom in mid-to-late June.

Head to Katsushika Ward in Tokyo for the annual Iris Festival held at Horikiri Iris Garden and Mizumoto Park. Horikiri Iris Garden boasts 6,000 irises of 200 varieties, while Mizumoto Park features 14,000 flowers of 80 varieties.

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.
