Japan's Only Fully Integrated Defence Event

DSEI Japan is the only large-scale, fully integrated defence event in the country, bringing together the global defence industry and Japan’s defence community.

With public sentiment shifting towards increased defence spending and changes to Japan’s pacifist stance, defence companies now have more opportunities to proactively engage with overseas Ministries of Defence.

As a result, events like DSEI Japan have gained significant importance, attracting strong domestic and international interest. The 2025 edition featured over 470 exhibitors from around the world and hosted a range of high-level conferences, seminars, and bilateral meetings with world-class speakers.

Through DSEI Japan 2025, attendees had the opportunity to experience a premier defence exhibition of the latest technologies in defence and security.
