Unfortunately, due to the new Corona Virus problem, we decided to postpone WTF 2020. In Japan, various sport events were cancelled recently (for example football matches). We discussed internally, and concluded that WTF should be postponed too. We are very sorry for the late decision.
However, we hope to reschedule the event and hold WTF 2020 in the future. We will announce the schedule again when the situation gets better.
