Yoichi Negishi is the craftsman at the helm of the family workshop founded in 1944 by Kuranobu Negishi in Tokyo's Sumida ward. Negishi Industry Co. began with producing metal gardening tools. By 1966, under Osamu Negishi, the company specialised in manufacturing joro, or bonsai watering cans, made from copper, brass, and stainless steel, renowned for their rain-like water flow. Yoichi's workshop is now Japan's only maker of bonsai watering cans. This multi-award-winning, family-run business consists of three master metalsmiths who handcraft each piece using traditional techniques, taking nearly half a day to create each can through meticulous high-temperature soldering. Yoichi's products are highly valued in the bonsai community for their quality, that reflects a deep connection to nature and Japanese heritage.
