Sorry, it has already closed in 2019.
Tokyo Game Show is held once a year in Japan. Many video game software and hardware companies attend this event.
You can also see a lots of cute staff and cosplayers.
When you go to TOKYO GAME SHOW on public day (not business day), there is a long line for the security check.
When I went there before 11:00 am on Saturday, I had to wait for about 40 minutes in the line. It was too hot under the sun shine!

When you go to this event, you have to buy a ticket. I recommend buying your ticket in advance because it is much cheaper and you can buy it 1 day before the event day.
You can buy tickets (in advance) at ticket machines in convenience stores, like SEVEN-ELEVEN. The instructions for buying tickets are in Japanese. If you don't understand Japanese, they can help you buy a ticket.
