Japan's economy is reeling from a series of major natural disasters over the past month.

Yatsushiro, Kumamoto Prefecture, where the Japan Meteorological Agency's highest seismic intensity of 7 was observed on July 28.

Roads, rice paddies, and fields are split and displaced in various places.

Viewed from the sky, the widening gaps stretch on endlessly.

These are the traces left by the Hinagu fault zone, which is estimated to have caused this earthquake.

The Hinagu fault zone extends about 81 kilometers in a north-south direction on the western side of Kumamoto, and in this earthquake, approximately 30 kilometers of the northern part of the fault was observed to have moved.

More than a month has passed since the earthquake, but recovery work has not been properly carried out around this fault zone due to concerns over aftershocks.

The same goes for this rest stop, where a fault line runs beneath the building, causing one side to sink.

[Rest Stop Owner: I am worried whether it is okay to rebuild the same building on the same fault line.]

Recovery is urgent, but future livelihoods are an even greater concern.

[Rest Stop Owner: Sales have dropped to about one-third of what they used to be, and the number of customers has decreased to about one-fourth.]

According to Japanese media and other sources, the economic damage from this earthquake, combining tourism, commerce, industry, and infrastructure, amounts to 220 billion yen, or approximately 1.8 trillion won in Korean currency.

It is not just earthquakes.

Since the middle of last month, unprecedented torrential rains have swept across the Japanese archipelago.

Rainfall far exceeding the average total precipitation for the entire month of August poured down in just a single day across Chiba Prefecture, Toyama Prefecture, Ishikawa Prefecture, and Fukui Prefecture, with the highest-level heavy rain special warnings issued at intervals of a few days.

In Chiba Prefecture, where 13 people died, losses from flooded homes and damaged roads were estimated to reach up to 11.1 billion yen, or about 100 billion won in Korean currency, while Toyama and Ishikawa prefectures suffered damages estimated at 35 billion won in Korean currency.

This means that in about a month, natural disasters have killed more than 50 people and caused economic damages close to 2 trillion won.

Amid heightened vigilance against large-scale disasters higher than ever before, the Japanese government today conducted a comprehensive drill for the first time, simulating a mega-earthquake with a magnitude of 8.3 off the coast of Hokkaido.

Prime Minister Takaichi also directly participated in the drill.

[Sanae Takaichi / Japanese Prime Minister (during a virtual press conference for the drill): Under the policy of placing human life as the top priority, the government will do its utmost in rescue and relief operations while providing prompt support to those affected by the disaster.]

The Japanese government designates September 1, the day the Great Kanto Earthquake occurred in 1923, as Disaster Prevention Day and conducts disaster preparedness drills every year.

During the Great Kanto Earthquake, which killed more than 100,000 people, the number of Koreans massacred due to discrimination amid the massive chaos reached at least several thousand.

Japanese civic groups and the Korean Residents Union in Japan (Mindan) held memorial services for the Korean victims of the Great Kanto Earthquake on its 103rd anniversary, respectively, urging the Japanese government to uncover the truth so that such a tragedy is never repeated.
