An Endeavor That Began with “Goza”

The southern part of Okayama Prefecture, including Kurashiki City and Hayashima Town, was once the center of igusa production in Japan.
In the 1960s (the 1950s), Okayama Prefecture accounted for about 80% of the nation’s production, most of which was grown around Kurashiki.

HAGIHARA INDUSTRIES INC.’s roots lie in this igusa culture.
In 1961, Hagiwara Shoten, a wholesaler of hanagoza in Nishi-Achi, Kurashiki City, built the Mizushima Factory to make polyethylene yarn as a substitute for the cotton yarn used as the warp in hanagoza.

The following year, in 1962, the Mizushima Factory became independent and “HAGIHARA INDUSTRIES INC.” was established.

Tarpaulins Protecting Our Lives

HAGIHARA INDUSTRIES INC.’s signature product is the tarpaulin.
Lightweight and highly waterproof, it can be used for many purposes, such as covering and wrapping items, making it indispensable in everyday life and at disaster sites.

They are also commonly used at events, such as for hanami picnics, community sports days, and festivals, and are relied upon in many aspects of daily life.

They are useful not only for emergency roof repairs when a roof leaks, but also during disasters to protect damaged buildings and secure temporary spaces.

Tarpaulin production began in the 1960s.
The original version was created as a cover for the beds of trucks operated by a major transport company.

Few people know that these tarpaulins are actually woven fabric.
Look closely at the surface and you can see the warp and weft threads crossing—this is truly a “woven material.”

Flat Yarn Technology Spreading Worldwide

The foundation of tarpaulins, soundproof sheets, and weed-control sheets is a long, narrow, tape-like fiber called flat yarn.

Weaving this flat yarn produces lightweight, durable, weather-resistant products. HAGIHARA INDUSTRIES INC. has top-level technology in this field in Japan, and its products are also exported overseas.

The company also manufactures and sells industrial machinery using this technology, having developed its own machines for producing flat yarn. Products used at a variety of sites around the world are made in Kurashiki.

Toward Circular Manufacturing

HAGIHARA INDUSTRIES INC. believes it is important to take responsibility not only for “making a product,” but also for what happens “after it has been used.”

One example is its horizontal recycling business, which collects used tarpaulins, washes and shreds them, and recycles them into raw materials.

The company makes effective use of limited resources and contributes to a sustainable society.
