30% of old buildings in Tokyo at risk of collapse in strong earthquake

The New Shimbashi Building (c1971) poses a high risk of collapse in a major earthquake. There are plans to eventually redevelop this building into a high-rise although negotiations with land-owners are taking longer than anticipated.

On March 29, the Tokyo Metropolitan Government released data from earthquake resistance inspections on public buildings built to the old ‘kyu-taishin’ earthquake codes (pre-May 1981). A total of 251 kyu-taishin buildings, representing a third of the total, were determined pose some risk of collapse in the event of an earthquake producing a seismic intensity scale (shindo) of a 6-upper or above. Of those, 156 were found to be at high risk of collapse.

The publication of this data is the result of a revision to the Act for Promotion of Renovation for Earthquake-Resistant Buildings that was introduced in November 2013. Under this revision, public buildings used by an unspecified number of people, such as hotels and commercial facilities, with a floor area over 10,000 sqm and built to the old kyu-taishin earthquake codes are obligated to carry out earthquake resistance inspections, the results of which are made public. This also applies to old buildings located alongside emergency roads. Although the revision requires building owners to carry out inspections, there are no obligations or requirements to conduct the retrofitting.Read more


Central Tokyo’s 3 wards to see 30%+ population growth by 2045

According to estimates by the Ministry of Health, Labour and Welfare’s National Institute of Population and Social Security Research, the population of central Tokyo’s three wards (Chiyoda, Chuo and Minato) is expected to increase by over 30% by 2045 as more and more people move to the city center. In contrast, the Tama district, which is the very western side of Tokyo and includes Hachioji, Tachikawa, and Mitaka, is expected to see a double-digit percentage drop in resident population. By 2045, Tokyo will be the only district out of Japan’s 47 prefectures to have seen an increase in population.Read more


Tokyo's latest flood map puts a third of city in risk zone

Flooding at Hirai Station, Edogawa-ku, following Typhoon Kitty in 1949.

On March 30, the Tokyo Metropolitan Government issued a new flood map based on a super typhoon hitting the nation’s capital. Approximately a third of Tokyo’s 23 wards, representing 212 square kilometers, could be at risk of being flooded by a storm surge. Almost all of the flood risk zones are located in the eastern part of Tokyo which is a low-lying district. Central Tokyo, with the exception of some of the waterfront districts, and the western side of Tokyo is on elevated ground and outside of the risk area.

If levees are breached, some areas in eastern Tokyo could see flood waters with a depth of over 50cm covering an area up 84 square kilometers for a week or longer. The maximum flood depth could exceed 10 meters in some zones. Sumida and Koto wards could see an average flood depth of around 7 meters.

The 1 in 1,000 ~ 5,000 year worst-case flooding scenario is based on the scale of the 1934 Muroto Typhoon that made landfall in Muroto, Awaji Island and Kobe. It caused tremendous damage in Osaka. Over 3,000 people lost their lives and 200,000 were left homeless. The typhoon brought a tide of 3 ~ 4 meters which inundated 49 square kilometers of Osaka City. The simulation is also based on the speed of Typhoon Vera, or the Isewan Typhoon, which struck the Tokai region in 1959.Read more

According to data compiled by Tokyo Kantei, the average asking prices of second-hand apartments in several districts on the manmade islands in Tokyo Bay have declined over the past two years.
