Major Exhibitions and Events in Japan in August 2026: 17 Must-Know Trade Shows Including JAPAN BUILD Osaka, CareTEX Tokyo Summer, and Japan International Seafood Show
When I was a child, one of the hardest parts of summer vacation homework was deciding on a topic for my independent research project. Looking back, choosing the subject may have been the most difficult part. Now, as an adult, every exhibition I visit brings new discoveries: “I never knew that,” or “I had no idea this industry existed.” I wish I could tell my elementary school self that exhibitions are full of ideas for research projects.
This August, we have once again selected exhibitions and events across Japan where visitors can encounter new industries, technologies, products, and perspectives.
We also recommend our guide to 40 exhibitions and events across Japan that are particularly suitable for students.
