Investment in Land-based Aquaculture Company in Okinawa
Japan System Techniques Co., Ltd. (JAST) has made an investment in Land Aqua Culture Innovation Ltd. (“LAC”) to support
the growth of land-based aquaculture business in Okinawa.

■ Background and Purpose for the Investment
In Japan, interest in land-based aquaculture has been increasing rapidly in recent years as a way for the fishing industry todeal with a variety of issues. There are restrictions on the amount of fish that can be caught and a decline in the volume of
specific species of fish caught, which are both associated with the current status of Japan’s food sector. Changes in the typesof fish caught due to climate change is another issue.
Japan has been behind other countries in the land-based aquaculture technology category in part because access to marine
resources in all areas of the country reduces the need for this technology. LAC sells circulatory aquaculture equipment thatuses physical filtration method, which has a much smaller environmental impact than conventional biological filtration does.
For many years, JAST has used its expertise and other strengths to contribute to creating solutions for social issues. JAST
believes that participation in the land-based aquaculture business will make it possible to be part of solutions for an evenbroader range of social issues by engaging in regional revitalization of Japan, devising ways to end food shortages, lowering
the environmental impact of various activities, and in other ways.
