Water Tanks
Water Tanks (HISHITANKTM)

We developed HISHITANKTM primarily to provide clean drinking water. We responded with a high level of quality to conditions such as earthquake resistance, hygiene, durability and workability which are required of water tanks used in various places such as condominiums, offices, factories, and leisure facilities. We also have an extensive lineup of water tanks for special purposes such as heat storage tanks, seawater tanks, and hot spring tanks.
