History
Our company was founded in April 1986 as a subsidiary of the major marine construction firm Toyo Construction Co., Ltd., primarily engaged in leasing formwork for breakwater core blocks.
In April 2004, Nippon Kenko Co., Ltd. became a 90% shareholder (with Toyo Construction holding the remaining 10%) and the company became a consolidated subsidiary. The business scope expanded from the original breakwater core concrete blocks to include products made from natural materials such as natural stone and timber, as well as the development and sale of landscape restoration products.
In April 2016, the company celebrated its 30th anniversary.
Revision of the standard formwork rental fee (effective November 15, 2024).
