「WOTA CORP. will accept pre-orders for the WOTA BOX and Shower Package for Shelters at the official website (URL: https://wota.co.jp/wota-box/) starting from February 11th 2019 .
We will also display the WOTA BOX and Shower Package for Shelters and accept pre-orders at the 23rd Yokohama Shinsai-Expo (Hall D, Booth No. 318) on February 7th 2019, with a limit of 100 units.
The WOTA BOX is a portable water treatment system capable of recycling 98% of used water. By using it with the Water Heater, Shower Tent, and Changing Room Tent included in the Shower Package for Shelters, anyone can set up a shower even in a situation where water is limited, such as in case of disasters. A usual shower uses about 50 liters of water but our system can reduce that to 1 liter per shower, making it possible to take 100 showers with just 100 liters of water.
Although water supply takes the most time to recover, preparation for water in cases of emergencies is insufficient. Bathing is essential for public health and hygiene, and is also stated in the national guideline. It is also the second biggest problem at evacuation sites*1. Despite this importance, provision was available only from a small number of sources such as the Japan Self-Defense Forces.
We have been working on our water recycling system since 2014 and provided shower services in the 2016 Kumamoto Earthquake, the 2018 Japan Floods, and the 2018 Hokkaido Eastern Iburi Earthquake. More than 300 people have used our shower at evacuation shelters, and we have received many voices of delight.
With the vision of making possible water freedom for everyone, everywhere, WOTA will keep devoting to create a country where everyone can set up their own showers in events of disasters.

WOTA has been providing showers at disaster sites since the 2016 Kumamoto Earthquake, using prototypes of the WOTA BOX and Shower Package for Shelters. When we served over 100 people with our showers at the 2018 Japan Floods and the Hokkaido Eastern Iburi Earthquake, word spread across the socal media, and interest towards our products increased rapidly.
We have interviewed the Japan Self-Defense Forces, fire departments, the Japan International Cooperation Agency, and municiple authorities, and applied their voices to imporove our product. In October of 2018, WOTA made a Comprehensive Partnership Agreement regarding water, with Kanagawa prefecture, and is cooperating with municiple authorities.
