Members of the International Olympic Committee chose Tokyo in September as the host for the 2020 Summer Games, despite Japan's ongoing troubles with containing nuclear waste at the Fukushima Daiichi facility, located about 140 miles north of the city.
Those committee members may feel a bit uneasy after 113 gallons of contaminated water leaked from the nuclear facility, crippled from damages sustained during a 2011 earthquake and tsunami.
According to Tokyo Electric Power Company, the plant's operator, the water overflowed from the top of one of the many storage tanks on the site. The tank was sitting on a slope and workers overestimated the amount of water the tank could hold.
The leaked water contained 200,000 becquerels per liter of beta-emitting isotopes, nearly 6,700 times more than the legal limit of 30 becquerels. TEPCO spokesman Masayuki Ono told reporters that workers are filling the tanks to the brim as a result of a storage shortage for the buildup of contaminated water. It is likely leaked contaminants have reached the ocean, he said.
TEPCO has long struggled to control waste leakage since the March 2011 disaster. Its worst reported incident since then occurred in August when 300 tons of radioactive water leaked from a storage tank.
The leak comes days after major Japanese fast-food chain Yoshinoya announced plans to grow rice and vegetables on a farm 60 miles southwest from Fukushima Daiichi.
Yoshinoya has put down a 10 million yen investment, though production is estimated to yield only a thousandth of the chain's annual needs, reported the Financial Times. Produce from the project will not be used in restaurants in the U.S. or the rest of Asia and is primarily a means to bolster the region, the company stated.
The farming industry was ravaged in after the 2011 disaster, which ranks alongside Chernobyl as the worst nuclear incident in history. Although Japan has used strict monitoring to ensure the safety of its food, Fukushima produce prices have continued to drop, reported Reuters.
