MIRAI Artificial-Light Plant Factory System

MIRAI is a Japanese plant factory company founded in September 2004 and incorporated in its current form in November 2015, based in Kashiwa, Chiba. It grows and sells lettuce, basil and other leafy greens to food companies from its own factory, and uses more than 20 years of operating experience to supply plant factory systems and know-how to partners in Japan and overseas.

The business has three parts: sales of fully artificial-light plant factory equipment, planning and consulting for new plant factory projects, and cultivation and management support to raise productivity and cut costs. Project work covers HVAC and dehumidification simulation, sanitary zoning, production planning, reviews of electricity, water and CO2 infrastructure, and water quality checks for cultivation equipment. MIRAI says factory cultivation involves more than 200 key factors and trains partner staff at its Kashiwanoha facility.

• Plant factory equipment: fully artificial-light cultivation systems optimised from more than 20 years of operation.
• Project planning: consulting on design, sanitary zoning and production planning for new factories.
• Engineering simulation: HVAC and dehumidification modelling plus electricity, water and CO2 infrastructure review.
• Water quality verification: checks of cultivation equipment water before start-up.
• Management support: consulting to raise productivity and lower operating cost of running factories.
• Training hub: hands-on staff training at the Kashiwanoha plant factory.

• Vietnamese food processors and salad producers building plant factories for consistent lettuce supply to fast-food chains.
• Industrial park investors converting buildings into indoor farms with Japanese operating know-how.
• Japanese-invested food companies in Vietnam replicating plant factory standards used in Japan.

• Production efficiency 50-100 times higher than traditional farming, according to the company.
• Uses about 1/50 of the water of traditional farming by recycling much of it.
• Pesticide-free, consistent output in quality and quantity regardless of outside weather.
• About 95% of each vegetable is edible, reducing waste for food processors and restaurants.

Food companies and restaurants in Asia want stable year-round supply of clean leafy greens at steady prices, which is driving interest in artificial-light plant factories in markets with harsh climates or limited farmland. Japanese plant factory know-how is being exported across Asia, and Vietnamese investors in high-tech agriculture can use turnkey equipment and operating support to shorten the learning curve.
