Erimo Farm

Wood Truss Use in Agricultural Building


Hokkaido prefecture, Japan


163,000 m2


Hokkaido Chuo Bokujyo


This is a project that resulted from Canada Wood Japan’s joint promotion efforts with the Japan Wood Truss Council (JWTC) in expanding opportunities for SPF dimension lumber use in the agricultural market segment. According to 2018-member survey data from the JWTC, truss use in large-scale non-residential structures jumped 54.1% and can be largely attributed to this agricultural building boom.

Erimo Farm, a new pig farm is built near Cape Erimo on the southernmost tip of Japan’s northernmost prefecture Hokkaido. The farm is owned by Hokkaido Chuo Bokujyo, breeding and raising pigs for pork production. On the 163,000 m² property that the company owns, it is building 9 pig barns with a combined total floor area of 18,120 m². Each pig barn being 20 m or wider and just over or under 100 m in length. On average, one of these buildings will typically consume approximately 150 m³ of SPF dimension lumber and in this case, it is not only used in roof trusses but also used to construct the pig barn walls as well. Saijo Sango supplied the structural lumber for the pig barns and the nail plate roof trusses were designed by Mitsubishi Shoji Construction Materials Corporation and fabricated and supplied by Iwakura.
