Read from the source code; the running server may differ. Descriptions are the server’s own words; hidden characters are shown as [U+…].

• building_seismic_checkBuilding Seismic-Standard Checkread-only

  Classify a building's seismic standard (旧耐震 / 新耐震 / 2000 wooden standard) from a build year and structure the USER provides, with risk context. This is NOT a safety verdict; direct the user to a professional 耐震診断 via taishin_subsidy_guide.

• geocode_addressGeocode a Japanese Addressread-only

  Convert a Japanese address to coordinates (lat/lon) and parse the prefecture/municipality, via the official GSI geocoder. Utility used by official_hazard_maps; call it directly when you only need coordinates.

• location_probabilityOfficial 30-Year Probabilities for a Locationread-only

  Report the OFFICIAL J-SHIS 30-year probabilities of reaching each JMA intensity at an address's ~250m mesh, severe case first. These are all-source probabilistic figures published by 地震本部, NOT the Nankai Trough scenario, and they are floors rather than ceilings. This server reports these official values; it does not compute its own.

• nankai_overviewNankai Trough Scale & Reachread-only

  Get the headline facts of the official 2025 Nankai Trough estimate (probability, worst-case casualties/loss, intensity-7 reach, tsunami) with sources. Start here to understand the scale; then call official_hazard_maps for a specific address.

• official_hazard_mapsOfficial Hazard Maps for an Addressread-only

  Geocode a Japanese address and return links to the OFFICIAL government hazard maps that hold the exact per-address values (predicted intensity, tsunami inundation, your municipal map). This server does not compute those itself; it bridges you to the authoritative source.

• preparedness_planPreparedness Plan for a Householdread-only

  Turn household details into a sourced preparedness plan: stockpile quantities sized to the official one-week guidance, what to do now, what to do when it shakes, and the structural route if a build year is given. Officially recommended minimums, never a verdict on survival.

• shindo_meaningJMA Seismic Intensity (震度) Meaningread-only

  Explain what a JMA seismic intensity level (5弱–7) actually means for people and buildings, using the official 気象庁 scale. The Nankai scenario projects up to intensity 7 across 10 prefectures.

• taishin_subsidy_guideSeismic Diagnosis & Retrofit Subsidy Guideread-only

  Route the user to subsidised/often-free seismic diagnosis (耐震診断) and retrofit (耐震補強) programs via the national directory, and explain the support framework. Amounts vary by municipality, so this routes and explains; it never quotes a figure.
