Okinawa is facing a water shortage, and measures are being taken to mitigate the danger.

According to the Okinawa Prefectural Enterprise Bureau, the water storage rate of the 11 water storage dams in the prefecture is 45.5 percent as of March 18, which is 29.9 percent lower than the average.

Though the bureau data indicates a low percentage yearly in March and April ahead of the rainy season in May and June, this year there have been significant drops in the levels. According to Okinawa Television Broadcasting, the last quarter of 2023 and first of 2024 showed a drastic drop and the water rate is now at the lowest it has been in a decade.

In 2004, Okinawa was in a similar situation and officials placed nighttime water supply restrictions. However, the restrictions were lifted before they could even begin thanks to 133 mm of rain starting a few days before the restriction dates.

Whether Okinawa will experience restrictions or the arrival of an early rain season, is yet to be seen. The Japan Weather Association forecasts nice weather with little to no rain for the next few weeks. Rainy season usually starts in May on Okinawa.

With the possibility of limiting water supply looming, the Okinawa Prefectural Government (OPG) is mobilizing its sea water conversion plant in Chatan to maximum capacity. In addition, local officials are urging for water conservation efforts in the prefecture.

When it comes to saving water, it’s an all-hands-on-deck situation. Whether you are a local, U.S. citizen or a tourist, be aware and help Okinawa make it through this dry season. 

Help conserve water on Okinawa

Water conservation measures recommended by Okinawa Prefectural Government:

·      Do not let water faucets run while you’re using the bathroom sink or the kitchen sink. Adjust the faucet valves to lower water pressure.

·      In the bathroom, avoid flushing more than once. Reduce flushing if possible.

·      In the kitchen, wash and rinse dishes with water in a tub, not with running water. Wipe oil off dishes before washing them. If you have water left after rinsing rice, use it to water plants.

·      In the shower room, shut off shower between lathering soap and shampoo. Reuse modest amounts of hot water in your tub without dumping it. Store water coming off a showerhead in a bathtub before it gets hot and use it to water plants.

·      For laundry, use the water in the bathroom and wash larger loads to reduce the frequency of running a cycle.

·      At the carwash, reuse hot water from shower room in a bucket for washing and rinsing your car. Or wash your car less frequently.

·      Other: Check and see if there’s any water leakage in your home faucets or toilets.  If you find any, request for repair immediately. Make use of rain, wells, and spring water. Utilize tools to save water. Bring water conservation to the attention of those around you.
