Artificial Light Plant Factory Established in Yabu City, Hyogo Prefecture, Japan

This initiative will involve cultivating loose-leaf lettuces*(non-head-forming lettuces) by leasing a gymnasium at an abandoned school (the former Minamidani Elementary School) from Yabu City in Hyogo Prefecture and building and operating an artificial light plant factory inside the gymnasium.

It is an industrial, academic and local government cooperation initiative, based initially on proposal by the School of Policy Studies of Kansei Gakuin University, which supports and conduct research on issues such as falling population in depopulated areas from the perspective of local revitalization, and supported by Yabu City which is active in promoting effective utilization of abandoned school.

By effectively utilizing an abandoned school, this initiative will revitalize and create new employment in an area suffering depopulation. For city of Yabu, this is the first participation in the industrial-academic-government business.

In addition, cultivation and facility expertise will be provided by MORIHISA Co., Ltd. (Kobe City, Hyogo Prefecture) a company that boasts 30-year history in research and development track record of plant factory.

The advantage of cultivating loose-leaf lettuces in artificial light plant factories is that crops are less affected by seasons, weather and other factors. There is also less risk of contamination by foreign substances as crops can be grown without the use of any agricultural chemicals and outside air is shut out.

Consequently, processing cost can be reduced, along with merits including reduction of impact on the environment and preservation of nutritional value. In addition, because there is no concern about crop failure, lettuces can be grown stably with high efficiency in growing racks up to eight racks high.

They aim for production capability of approximately 3,000 plants per day, or approximately 1 million plants (84 tons) per year after half a year past the launch of lettuce cultivation business.
The lettuces will be distributed and sold through the cooperation with local companies. Further, the lettuces are scheduled to use the supply system of ORIX Group’s nationwide branch network which includes food supermarkets and restaurant businesses. They will also supply accommodation facilities run by the ORIX Group.

Approximately 50,000 tons of non-head-forming lettuces are grown in Japan. Of this amount, non-head-forming lettuces harvested in plant factories accounts for about 2,500 tons (approximately 5%).
There are concerns in Japan that the volume of lettuce produced will decrease in the future due to the increasing age of agricultural workers and the lack of successors taking over agricultural businesses.

Furthermore, in recent years, spikes in lettuce price due to abnormal weather and unease regarding food safety as a result of the effect of PM2.5 and other factors has prompted a rising need in the food service industry and other sectors for a stable supply of lettuces at stable prices unaffected by the season, weather or other factors.

・Artificial Light Plant Factory
A factory that uses artificial light to cultivate plants under almost bacteria-free conditions. As cultivation is largely unaffected by seasons, weather or other factors, vegetables can be grown stably without using agricultural chemicals. Broadly speaking, there are two types of plant factory: factories that use only artificial light and factories that use natural sunlight.

* A type of lettuce that grows as leaves without forming into a head. Ordinary lettuces are called head lettuces.
