Japan is no stranger to natural disasters, and each one offers a lesson on the need to be as prepared as possible.

A July 3 mudslide in Atami, Shizuoka Prefecture, killed at least 21 people and damaged around 130 buildings in the town’s Izusan district. An investigation is underway into how the disaster came about, but the district was designated by a national government hazard map as being at risk from landslides.

As recovery work there continues, Tropical Storm Nepartaki is expected to make landfall as early as Tuesday. The resulting rains in the Kanto area, including Tokyo, and the Tohoku region are creating concerns about possible flooding.
