In order to prepare for an earthquake directly hitting the capital, 12 of Tokyo's 23 wards have announced that they will subsidize the cost of earthquake resistance diagnosis and renovation for wooden houses built by 2000 to new earthquake resistance standards starting in the new fiscal year. .
Earthquake-resistant standards for housing were significantly revised in 1981, but the Great Hanshin-Awaji Earthquake caused damage to even so-called "new earthquake-resistant" wooden houses built to new earthquake-resistant standards, so the country revised the standards again in 2000. I reviewed it.
When NHK interviewed Tokyo's 23 wards, it was learned that 12 wards will subsidize the cost of seismic diagnosis and renovation for ``new earthquake-resistant'' wooden houses built by 2000, starting in the new fiscal year.
The 12 wards that have announced new policies are Bunkyo, Taito, Sumida, Meguro, Ota, Setagaya, Shibuya, Teshima, Kita, Arakawa, Itabashi, and Nerima.
Seven wards of Minato, Shinjuku, Shinagawa, Suginami, Adachi, Katsushika, and Edogawa have already implemented the subsidy, meaning that 19 of Tokyo's 23 wards will receive subsidies for "new earthquake-resistant" housing.
Among these, Arakawa Ward has so far subsidized the cost of earthquake-proofing houses built before 1980, but in order to further prepare for an earthquake directly hitting the Tokyo metropolitan area, Arakawa Ward has subsidized the cost of earthquake-proofing houses built before 1980. We have decided to include homes in this area from the new fiscal year.
The plan is to subsidize up to 300,000 yen for the cost of earthquake resistance diagnosis and up to 1.8 million yen for the cost of earthquake retrofitting.
Hironori Murayama, head of the Arakawa Ward Housing and Urban Development Division, says, ``I hope people will use the subsidy system to check whether their own homes are truly safe.''
Some people carry out reinforcement work due to lack of earthquake resistance.
It has been pointed out that some of the "new earthquake-resistant" wooden houses built up to 2000 lack earthquake resistance, and some are undertaking reinforcement work.
Last August, Takanori Miura of Kamakura City, Kanagawa Prefecture, purchased a two-story wooden house built in 1988 to the new seismic standards.
However, as a result of an earthquake-resistance assessment, it was determined that the placement of the walls and the anchoring of the pillars to the foundation were insufficient to withstand shaking, and that there was a ``high possibility that the building would collapse'' in the event of a tremor of magnitude 6 or above.
Mr. Miura carried out reinforcement work by reinforcing the walls by adding braces and fixing the joints between the pillars and the foundation with special metal fittings.
In addition to the cost of purchasing the house, he spent about 3 million yen on reinforcement work, but Kamakura City does not have a system to subsidize the cost of reinforcing ``new earthquake-resistant'' houses.
Mr. Miura said, ``I was surprised to be told that the earthquake resistance was low even though it was built according to new earthquake resistance standards.It can't be helped that it would cost more to live in peace of mind, but I wish there was a subsidy system from the city.'' I'm talking.
More than 80% of “new earthquake-resistant” wooden houses lack earthquake resistance
A private organization formed by construction companies that carry out seismic reinforcement work carried out seismic diagnostics on "new earthquake-resistant" wooden houses built up to 2000, and found that more than 80% of them lacked seismic resistance. was doing.
In the Great Hanshin-Awaji Earthquake of 1995, even wooden houses built after 1980, when seismic standards were significantly revised, had walls that were unevenly placed and pillars not fixed properly. There was damage.
For this reason, the government reviewed its earthquake resistance standards again in 2000 and established specific standards for things such as the placement of walls and the method of fixing pillars.
The ``Japan Wooden House Earthquake Reinforcement Business Cooperative Association'' conducted seismic diagnosis of ``New Earthquake-resistant'' houses built up to 2000 over the 18 years up to December last year, and found that over 14,000 houses had been earthquake-resistant. Approximately 86% of these buildings lacked earthquake resistance.
The association calls for reinforcement work to be carried out if a lack of seismic resistance is identified, such as reinforcing the wall with braces or fixing the joint between the pillar and foundation with special metal fittings.
However, even if a diagnosis indicates a lack of earthquake resistance, only about 30% of cases lead to reinforcement work.
The association's secretary general, Yusuke Seki, says, ``The cost is the biggest reason why seismic reinforcement has not progressed, so if there was a subsidy system from the government, I think the number of people who would consider diagnosis and reinforcement would definitely increase.''
What is the subsidy amount in Tokyo's 23 wards?
Subsidizing the cost of earthquake-proofing the ``new earthquake-resistant'' housing that is spreading in Tokyo's 23 wards. How much will be subsidized in each ward?
All eligible for the grant are wooden houses built to new earthquake resistance standards by 2000.
Of Tokyo's 23 wards, 12 have announced plans to begin providing subsidies in the new fiscal year: Bunkyo, Taito, Sumida, Meguro, Ota, Setagaya, Shibuya, Toshima, Kita, Arakawa, Itabashi, and Nerima.
