1. Property Location Risk
Property location risk means the risk of vacancy or damage or decline in income due to reasons derived from the location of the property. This includes disasters (earthquake, flooding, or landslides), accidents or crime, or popularity including access.
Also, some developments can be those developed without proper marketing research. This includes, for example, the cases where may seem a good deal,
Some risks are specific to whether the property is located in an urban area or a regional area.
To mitigate this property location risk, make sure to do the following:
(1) Better understanding of the neighbourhood
Ask your agent about the accessibility of the location, surrounding facilities and institutions, and future developments, so the location can fetch long-term demand.
(2) Check the hazard map of the area
Municipalities usually have what they call “Hazard Maps” accessible. A hazard map clearly indicates areas where damage is anticipated (such as flood-prone zones), evacuation sites, and evacuation routes using colors and symbols when natural disasters such as floods, earthquakes, or landslides occur.
2. Natural Disaster Risk
Natural disaster risk is the risk that a property may be damaged or lost due to natural disasters. There are natural disasters unique to Japan. This includes earthquakes, typhoons, and floods.
To mitigate this natural disaster risk, first understand the types of disaster and what they are and check the possibilities of natural disaster in each area.
Typhoon
Typhoons most frequently approach Japan between July and October, with August and September being the peak months.
Typhoons bring heavy rain, flooding, strong winds, high waves, and storm surges, resulting, sometimes, in power or water outages.
Heavy rain/snow
Heavy rain can cause flooding, landslides, and debris flows.
In recent years, Urban Heat Island (UHI) effects have caused sudden downpours (locally called 'guerrilla rainstorms') in urban areas.
Heavy snow, on the other hand, causes houses to collapse, accidents due to frozen roads, or injuries while removing snow from the roof.
Flooding
Flood disasters occur when river flow increases abnormally due to heavy rain or snowmelt, leading to embankment erosion, breaches, bridge washouts, and other types of damage.
Landslide/debris flow
Landslides and debris flows occur when heavy rain or earthquakes trigger collapses of mountains or slopes, or when mud and rocks mixed with water flow out of rivers. It is important to identify the hazardous areas and the evacuation route, and if you sense danger, evacuate immediately in a direction perpendicular to the flow of debris.
Earthquake
Japan is located on the “Ring of Fire” where it is prone to earthquakes and volcanic activity.
Earthquakes cause tsunamis, building collapses, fires, landslides, and soil liquefaction.
You may be wondering if the houses in Japan are earthquake-proof.
The Building Standards Act in Japan stipulates minimum requirements to ensure hygiene and security, including seismic standards of buildings. The stricter seismic standards were enacted on June 1, 1981 (new seismic standards), with the aim of protecting human life by preventing the collapse of buildings even during major earthquakes of seismic intensity 6 upper to 7.
On the other hand, you need to be cautious if you are planning to buy a house more than 40 years old, since the house may not conform to the new seismic standards.
Tsunami
Tsunami causes various damages, including drowning due to flooding, damage to and loss of homes, damage to and collisions involving ships, and fires following tsunami damage.
Volcano Eruption
Volcano eruptions cause large volcanic bombs, pyroclastic flows, snowmelt-type volcanic mudflows. When heavy rain falls on areas where volcanic rocks and ash from eruptions have accumulated, the risk of debris flows and mudslides increases.
Check the hazard maps prepared by each municipality to understand the natural disaster risks in your area (https://disaportal.gsi.go.jp/) and prepare for emergencies.

Risk: Property location risk is the risk that location-specific factors such as disasters, crime, poor accessibility, or weak demand negatively affect occupancy or income.
Mitigation: This risk can be mitigated by conducting detailed neighborhood due diligence and reviewing municipal hazard maps before purchasing a property.
2. Natural Disaster Risk
Risk: Natural disaster risk is the risk that earthquakes, typhoons, floods, landslides, or volcanic activity damage or destroy a property.
Mitigation: This risk can be mitigated by understanding regional disaster exposure, checking hazard maps, and selecting properties that comply with modern seismic standards.
