Walking on Drift Ice
The Tokyo Game Show is an annual trade show for video game developers held at Makuhari Messe convention center just outside of Tokyo. Held since 1996, it is one of the world's biggest game shows, which companies use as a venue to launch new products and show off their latest innovations and technology. The show is held over four days. The first two days are business days for invited members of the industry and media, while the third and fourth day are open to the general public.
The Tokyo Game Show is split up into different areas, including the general exhibition area where you can see the latest game debuts and trailers, as well as try out the newest demos from a wide range of developers.
