Demolition underway on Omotesando public housing complex
Demolition of the old Aoyama Kitamachi Apaato housing complex in Omotesando is underway. Asbestos removal from four buildings is currently being carried out. Asbestos sheeting and spray-on insulation was used in some of the buildings’ rooftop waterproofing, plumbing insulation, and chimneys.
The city-owned public housing estate will soon be replaced with high-rise residential, aged care facilities and retail space.
The Tokyo Metropolitan Government has chosen six developers to partake in the project, including Tokyo Tatemono, Mitsui Fudosan, Kajima Corporation and Maeda Corporation.Read more
Nakano’s last surviving thatched-roof house to be demolished
The 160+ year old Hosoda Residence in Nakano, Tokyo, is expected to be demolished soon to make way for a city road. The road plan was enacted in 1966, but, as is the case with many of Tokyo's old road plans, remained dormant for several decades. The city obtained approval from the national government for the road construction in 2015 and plan to have the project completed by 2020.
This is the sole surviving thatched-roof house in Nakano Ward, and a very rare example of a typical farmhouse from the period in Tokyo’s 23 wards. Read more
Voting ratios relaxed to encourage speedier demolition of earthquake-damaged buildings in Kumamoto
On September 30, the Japanese government voted in favour of enacting an exemption to the apartment redevelopment law in order to help speed up redevelopment of buildings damaged by the Kumamoto earthquake in April. Under the special exemption, the voting ratio for demolishing an apartment building and selling the land has been reduced to 80% for damaged buildings in Kumamoto. This is the second time the exemption has been applied. It was first applied to three buildings damaged by the 2011 Tohoku disaster in Sendai city.
Ordinarily, 100% of apartment owners must agree before a building can be demolished and the land sold. However, if the building has been seriously damaged in a major earthquake, the ratio can be reduced to 80% if certain conditions are met. Nevertheless, obtaining 80% agreement is still a difficult task.
According to Kumamoto City, 19 apartments buildings were considered to be completely destroyed, 21 suffered major damage, and 52 suffered partial damage in April.Read more

Faulty apartment building in Yokohama to be demolished next year
Last month, two years after the building was found to be tilting, the owners association of a condominium complex in Yokohama voted in favour of redevelopment.
In October 2015 it was announced that several of the foundation piles in one of the buildings were not sunk deep enough to reach bedrock and a 2 cm difference in height had developed between the buildings. Residents were assured by the developer that the building posed no immediate risk and still met earthquake-resistant standards. However, further inspections found that the building would not withstand an earthquake producing a seismic intensity of 5+ or higher. In August 2016, Yokohama City issued the developer with a correction order under the Building Standards Act.
The 12-storey condominium was built in 2007 and contains over 700 apartments.
Demolition of all four blocks in the complex, including the one that has already started to show signs of tilting, will start as early as April 2017. It will be replaced by new buildings which should be ready for residents to move into from late 2020. The developer will bear the 40 billion Yen (390 million USD) cost of redevelopment.
Under the Condominium Unit Ownership Act, 80% of owners must vote in favour in order to redevelop a condominium. In this particular case, 99% of owners were in favour of rebuilding. Those that were not in favour will be forced to sell their apartments to the owners association, as outlined under the Act.
It is likely that the redevelopment committee will select a different developer to carry out the reconstruction, rather than the original developer. Apartment owners who plan to move into the new building will be provided with temporary housing in the meantime. In addition to shouldering the cost of redevelopment and temporary accommodation, Mitsui is providing each household with 3 million Yen in compensation.
