6 FAQs about [Japan s water storage]

Does Japan have a water supply?

Access to an improved water source is universal in Japan. 97% of the population receives piped water supply from public utilities and 3% receive water from their own wells or unregulated small systems, mainly in rural areas. Access to improved sanitation is also universal, either through sewers or on-site sanitation.

How much water does Japan use a year?

Water use is about 83.5 km3, or 20% of water availability in an average year. However, there are large variations in the utilization rate between years and regions. For example, in the coastal part of the Kantō region that includes Tokyo the utilization rate is over 90% in a dry year. In the relatively dry north of Kyushu it is more than 50%.

Is Japan a water-stressed country?

While Japan is not a water-stressed country per se, water availability varies substantially between years, seasons and regions leading to regular and serious water shortages. On average over the period 1971–2000, water resources in Japan stood at 420 km3 per year. At 3,300m3 per capita and is below the global average.

When was piped water first used in Japan?

The first modern piped water system in Japan was completed in 1887 in the port city Yokohama, using surface water treated by a sand filter. By 1900, seven cities had piped water supply and by 1940 about one third of the population was connected to piped water systems.

Is it safe to drink nuclear water in Japan?

Japan said tritium levels in the water will be below those considered safe for drinking under World Health Organization standards. "Meanwhile, it is not the practice of any country to drink the water discharged from nuclear facilities," Japan's mission to the International Atomic Energy Agency said last week.

What is Japan's water release plan?

Tepco has been filtering the contaminated water to remove isotopes, leaving only tritium, a radioactive isotope of hydrogen that is hard to separate. Tepco will dilute the water until tritium levels fall below regulatory limits before pumping it into the ocean from the coastal site.
