Wisdom of Home Building, Kagoshima Prefecture

Kagoshima Prefecture, where volcanic ash measures are essential! Introducing house building aimed at extending the lifespan of buildings.

This document introduces house construction in Kagoshima Prefecture, which implements measures against volcanic ash. Volcanic ash consists of small particles, but when a large amount falls, it can cause various damages to transportation, lifelines, agriculture, and health. The approach focuses on preventing ash from entering homes, making it less likely to accumulate, easier to remove, and actively protecting against ash, thereby reducing maintenance efforts, improving comfort, and extending the lifespan of buildings. Houses designed with these measures are called "Kokuhai Jutaku" (ash-resistant houses), and their promotion is underway. 【Main Measures】 《Kokuhai Jutaku》 ■ Roof: Use of ash-resistant tiles and similar products ■ Openings: Adoption of airtight sashes and double sashes ■ Ventilation Method: Utilizing airflow from under the floor to avoid direct introduction of outside air ■ Finishing: Smooth finishes with minimal irregularities (such as porcelain tiles) ■ Eaves and Gutters: Steeper slopes and shorter spacing between vertical gutters *For more details, please refer to the PDF document or feel free to contact us.
