1. Utilization of domestic timber is encouraged in Japann

However,due to the worsening profitability of the forestry industry,the maintenance of forests is not enough,and the functions of forests are reduced.

It is important to sustain the cycle of “planting”, “maintaining”, “harvesting”, “using” for the function of the forest to be sustainable.

2. Building fire resistant wooden buildings is now possible

4.Fire-resistant wooden structure is made possible by using fire-resistant gypsum boards as cladding

Fire-resistant buildings are required to have the ability to keep standing without breaking down even after the fire has extinguished, which is achieved by making the main structure a fire-resistant structure.
As for fire-resistant wooden buildings, the wooden structure can usually be protected from fire by cladding the wooden structure with fire-resistant gypsum boards.^*

*In case of fire-resistant wooden structure with cladding

1.Suitable for cramped small land plots

By making the building as a fire-resistant wooden structure, it is possible for the construction to be done without using heavy equipment such as a large crane because its materials are lighter than other construction methods such as reinforced concrete structure or steel structure.
It can be flexibly adapted to flag lots and cramped small lands that can be obtained relatively inexpensively.

6.Preferred “comfortable wooden house”

When questioned about which construction method to use if building or buying a house in the future, 8 out of 10 people in Japan answered that they would like to choose a house constructed of wood. The charm of the warmth of wood and its relaxing effect is widely known

A fire resistant wooden building can be built using the methods specified in "Ministry of Construction Notification No. 1399 of 2000" or by acquiring "Individual Certification"

The main structural parts are made fire resistant using the methods in "Ministry of Construction Notification No. 1399 of 2000" or are "Individually Certified".

2．Membrane construction in which gypsum board (with fireproof coating) is connected throughout

When using the membrane construction method, the specifications and fit of each part are designed based on the following concepts
