## About

Founded in 2014 and based in Tokyo, Japan, WOTA CORP. develops a residential water reuse and circulation system. In April 2026, WOTA raised an undisclosed amount in series C funding from Awagin Capital, Elematec Corporation, NCB Venture Capital, Persol Holdings, Mitsubishi UFJ Trust and Banking, and SMBC Nikko Securities, with participation from Osaka Iron & Steel Co., Ltd., MIWA TECH, Yamakoshi Group, Global Infrastructure Management, Shinkin Capital, NAKABAYASHI CONSTRUCTION Co., Ltd., Tokio Marine and Nichido Fire Insurance, FUJINO KOUGYO Co., Ltd., Proflex, and HONCHO CHEMICAL INC. This round was part of a larger equity and debt financing.


WOTA offers two key products: the WOTA BOX and WOSH. The WOTA BOX is a versatile water system designed for outdoor use and disaster situations, capable of regenerating over 98% of wastewater for cyclical reuse. WOSH is a handwashing station that also recycles more than 98% of the water used, featuring a smartphone sterilization function for enhanced hygiene.

The company plans to use the April 2026 funding to strengthen long-term deployment of sustainable water infrastructure and disaster-resilient water systems both in domestic and international.
