"Saigai Map" Launches Kansai Disaster Risk Score Tool—Assess Nankai Trough Impact by Address

Mycat Inc. (Headquarters: Meguro-ku, Tokyo) has launched a new disaster risk score diagnosis tool specialized for the three Kansai prefectures (Osaka, Kyoto, and Hyogo) as part of its AI disaster risk diagnosis service, "Saigai Map" (https://saigaimap.xyz).

Features of the Kansai Disaster Risk Score Diagnosis Tool

By simply entering an address in one of the three Kansai prefectures, the tool instantly displays a composite disaster risk score for that location on a scale of 0 to 100.

Input Items

• Address (within Osaka, Kyoto, or Hyogo prefectures)

Output Content

• Composite disaster risk score (0-100 points)
• Breakdown by risk type (earthquake, flood, landslide, tsunami, storm surge)
• Nankai Trough earthquake impact score
• Liquefaction risk assessment (for applicable areas)
• Advice on which risks to prioritize for preparation
• Information on nearby evacuation shelters

Disaster Risk Profile of the Kansai Region

The Japanese government's Earthquake Research Committee estimates a 70-80% probability of a magnitude 8-9 earthquake occurring along the Nankai Trough within the next 30 years.

Osaka Prefecture: The Osaka Plain is a large lowland area with flood risks from the Yodo and Yamato rivers. It faces a combination of risks, including a direct-hit earthquake from the Uemachi fault zone, tsunamis along the Osaka Bay coast, and soil liquefaction around reclaimed land.

Kyoto Prefecture: Kyoto Prefecture faces earthquake risks from the Hanaore and Mitoge-Kyoto Nishiyama fault zones. The Katsura and Kamo river basins have experienced flooding in the past, and the northern region along the Sea of Japan is also at risk for heavy snowfall.

Hyogo Prefecture: Hyogo Prefecture has multiple active faults, including the Yamasaki fault zone. Landslide risks have been identified at the southern foot of the Rokko Mountains, along with storm surge risks on the Seto Inland Sea coast.

Background

The Noto Peninsula Earthquake in January 2024, which caused an estimated 2.2 trillion yen in economic damage (Source: Mitsubishi Research Institute), has renewed awareness of the importance of preparing for large-scale earthquakes. Furthermore, a survey by Kokumin Kyosai coop reveals that 64.5% of people have never participated in a disaster drill (Source: Kokumin Kyosai coop).

This tool is designed to be the first step in disaster preparedness by helping users understand the risks specific to their location, providing a highly accurate diagnosis specialized for the Kansai area.
