Earthquake risk zones
Lowest risk of earthquake – Rank 1
The danger of building collapses and spreading fires from earthquake disasters, and the ease (or difficulty) of evacuation, firefighting and rescue activities are comprehensively measured in the general risk levels that have been announced by the Tokyo Metropolitan Governments’ Bureau of Urban Development. The Tri-Seven Roppongi location was ranked “1”, the lowest level among the five risk levels.

Located outside assumed tsunami area -31m above sea level
Among the types of earthquakes that can be expected in the vicinity of Tokyo Bay, the Genroku type Kanto earthquake (expected 8.2 magnitude) is assumed to have the most impact from a tsunami. But even if he defined worst-case senario were to occure, in which “sea walls would become dysfunctional after the ground subsides due to liquefaction”, the location in question is outside of the predicted tsunami area.
Low possibility for liquefaction
With respect to the liquefaction that would cause great damage to the city infrastructure at the time of a metropolitan area disaster, and also according to a simulation study that assumed an earthquake in the northern area of Tokyo Bat would have the maximum seismic intensity within Tokyo’s Minato-ku (magnitude 7.3 expected), the area in question is designated as having a low possibility of liquefaction.
Located outside assumed flood zone over 0.2m
Minato flood hazard
With regard to the frequent occurrence of “guerrilla heavy rain” in recent years, the results of a simulation of the Tokai heavy rain that caused extensive damage in the Tokai region in September, 2000 (total rainfall 589mm, maximum rainfall of 11mm per hour) show that the location in question is located outside of the area predicted to be inundated with 0.2m or more, and is predicted to incur the least amount of damage
