July in Japan marks the real start of summer.
The rainy season comes to an end, temperatures rise, and the country goes into festival mode!
Look out for local fireworks festivals and people dressing in yukata.
Whether you’re travelling or enjoying Japanese culture from home, July is full of colour and tradition! Here are some ways to celebrate:
Festivals and events in July
Tanabata
Tanabata, the Star Festival, is celebrated on 7 July and is based on a well-known folk tale.
The story tells of Orihime, a skilled weaver princess (represented by the star Vega), and Hikoboshi, a cowherd (represented by the star Altair). The two fell in love but neglected their duties, so they were separated by the Milky Way and only allowed to meet once a year on the seventh day of the seventh month.
On Tanabata, people write wishes on colourful paper strips called tanzaku and hang them on bamboo branches, hoping their wishes will come true.
You will see shopping streets, schools and homes decorated with these colourful streamers and paper ornaments. The festival has an optimistic and celebratory feel that marks the heart of summer in Japan.
Tanabata is not a national holiday, so expect business as usual if you’re visiting Japan in July.
Marine Day (Umi no Hi)
Marine Day is a national holiday held on the third Monday of July. In 2026, it will fall on 20 July. It’s intended as a day to show gratitude to the ocean and honour Japan’s close relationship with the sea.
Marine Day is a relatively new holiday, so there aren’t really any specific traditions.
Some coastal towns hold events, such as festivals, performances, or community beach clean-ups. Many people head to the coast to enjoy the start of summer holidays. Some aquariums also hold special events on this day. And many people – especially inland – simply enjoy the extra day off!
