Shitagau Noguchi introduced the Casale design ammonia synthesis process into Japan in 1924 (Taisho 12), and he was the first person to succeed in industrializing ammonia in Japan. He used the Gokase River for hydroelectric power generation and established the Japan Nitrogenous Fertilizer Company in Nobeoka, which was the forerunner of today's Asahi Chemical Company.

Casale design ammonia synthesis equipment is the first in the world to succeed at synthesizing ammonia for practical application. It uses a manufacturing method which synthesizes ammonia from hydrogen and nitrogen as a base. This is the method which Italian scientist, Dr. Luigi Casale invented. Such ammonia synthesis equipment is currently on display at the Asahi Chemicals Medical Factory Plaza.

The Nobeoka based Asahi Chemical Company has developed greatly over the years into a company that is active on a world wide scale.
Various information and products related to the Asahi Chemical Company's history of development and incorporating some its leading edge technology are on display at the company's Exhibition Hall.
By car it takes approximately 15 minutes to get to the Exhibition Hall from JR Nobeoka Station.
