Ahead of the 2020 Summer Games, the transport ministry said Tuesday it plans to strengthen measures to help foreign visitors in the event of a massive earthquake in the Tokyo area.

The ministry will beef up airports and railways' quake resiliency to ensure vital transportation infrastructure can remain operational in the event of a major temblor, while introducing more signs with symbols to help foreign visitors locate evacuation routes and areas.

The ministry will also warn visitors about the possibility of an earthquake through its English-language website.
