From 1 to 12 August, NATO will participate in the 2025 edition of the World Expo in Japan. Taking place in Osaka, Kansai, the theme for this year's Expo is "Designing Future Society for Our Lives", with the sub-themes of "Saving Lives", "Empowering Lives" and "Connecting Lives". This landmark event is expected to welcome over 28 million visitors, making it one of the largest global gatherings after the FIFA World Cup and the Olympic Games.

With a long tradition dating back to 1851, World Expos (also known as World's Fairs) are grand international exhibitions where countries unite to showcase their cultures, technologies and innovations, fostering global cooperation and exchanging new ideas. Since 2000, they have taken place once every five years.
Osaka's Expo is taking place over several months, from 13 April to 13 October. The "NATO Days" will take place in August aligning appropriately with the "Peace, Human Security and Dignity Week." Although NATO is not an official Expo participant, it will collaborate closely with NATO member countries hosting pavilions at the event - a partnership facilitated by the Mission of Japan to NATO and coordinated through Norway and Romania, NATO's Contact Point Embassies for Japan.
This collaboration is a prime example of NATO's broad framework of partnership with Japan. Since the early 1990s, NATO and Japan have been working together on a range of global security challenges, enhancing political dialogue and practical cooperation, and upholding and strengthening the rules-based international order. This complements the firm relationships between NATO and its other partners in the Indo-Pacific region: Australia, the Republic of Korea and New Zealand.
NATO's engagement activities during the "Peace, Security and Dignity Week" will emphasise the importance of multilateralism and cooperative security in addressing today's complex challenges, including cyber security, hybrid threats, information threats, the Women, Peace and Security agenda, emerging technologies, and industrial cooperation. The events will also showcase NATO's Science for Peace and Security Programme, promoting joint scientific research, technological innovation and knowledge exchange.

Like many other countries and organisations who will be represented in Osaka by mascots, NATO will be travelling to Japan with a new version of its long-term unofficial mascot, the NATO Hedgehog. Hedgehogs are peaceful animals, but formidable and resilient when attacked, making them the perfect representation of NATO's role as a defensive alliance.
