If you're a fan of Japan's festivals and fireworks, July is a perfect month to visit Tokyo. From Tanabata Matsuri celebrations at the start of the month, to the breathtaking Sumida River Fireworks Festival in late July, there are great memories to be made throughout the month.
The average temperature in Tokyo in July is 28.7℃ (83.7℉). But there are highs of a whopping 37.3℃ (99℉), and temperatures can exceed 30℃ (86℉) for days at a time. The rainy season lasts until early July, so the weather can be rainy, hot, and humid. Make sure to bring breathable clothes that you can feel comfortable in. UV rays are very strong, so a lightweight folding umbrella with UV protection is helpful for protecting against both rays and rain.
Note: This guidance is based on meteorological data for 2024.
Design Festa is a huge international art and design event. Held at Tokyo Big Sight, it brings together over 10,000 artists representing a broad range of creative activities, including music, painting, fashion, crafts, photography, performances, and more. At Design Festa, visitors can hear directly from artists about their work, and can participate in workshops and other experiences, too.
In the past, the gardeners of Iriya created around 1,000 varieties of morning glory plants through cross-pollination. That history is celebrated at the annual Iriya Morning Glory Festival—the largest festival in Japan dedicated to morning glory plants. There are around 30 stalls specializing in them, and around 100 other stalls to enjoy as well.
On July 7, people celebrate the Japanese traditional holiday of Tanabata by writing wishes on strips of paper, tying the paper to bamboo, and praying to the stars. It is said that for just this day once a year, Weaving Princess Orihime and Cowherd Hikoboshi cross the Milky Way to be together. Their reunion is celebrated nationwide during the Tanabata Matsuri, with events all over Tokyo. Wander through the Tanabata decorations at Shitamachi Tanabata Matsuri, then head to Tanabata Kigansai at Tokyo Daijingu Shrine, where people pray in hopes of meeting that special someone.
Those who offer a prayer at Asakusa's Sensoji Temple on July 9 or July 10 are said to receive 46,000 days' worth of blessings. The Hozuki-ichi—a fair where hozuki (Japanese lantern plants) are sold—is held during this auspicious period. In Japan, hozuki are said to guide the spirits of ancestors to the family home for the summer Obon festival, so they are popular decorations at this time of year.

Goldfish-scooping stalls are a quintessential part of Japanese summer festivals. Tokyo's Edogawa City is famous for its goldfish, and it celebrates them each year at an annual festival. Goldfish are displayed and sold, and there are goldfish-scooping competitions. Visitors to Sumida Aquarium, located inside TOKYO SKYTREE TOWN, can see around 15 types of goldfish. There, you can learn all about the creatures themselves, as well as their cultural significance.
Kagurazaka Matsuri is one of Tokyo's most popular summer festivals. It features the Japanese Lantern Plant Market, and the Awa-odori Dance Festival. On the days when the market is held, the streets are lined with yatai food stalls, and Japanese lantern plants are sold on the grounds of Bishamonten Zenkokuji Temple. Then comes the Awa-odori dance performances, which notably take place on a hill road.
Sumida River Fireworks Festival is Tokyo's most popular fireworks festival: On average, 950,000 people attend each year. Close to 20,000 fireworks light up the sky above the Sumida River in Asakusa, making this one of Japan's biggest fireworks events.
