The Story of Vegetus

Research and the development of vertical farms (also called plant factories) in Japan has been ongoing since the 1980s, but has not reached the stage of large-scale business production until recently. In this regard, Vegetus is a pioneering product that was launched in 2008, at the dawn of the industry.
Spread’s founder and CEO, Shinji Inada had originally been engaged in the fresh produce distribution business, and came across vertical farming based on his strong concern about Japanese agriculture due to the volatility of fruit and vegetable prices arising climate change, the decrease in agricultural producers, and the lack of successors. At the time, neither the quality nor price of vertically farmed vegetables had been on par with those of outdoor produce, so Inada independently developed Vegetus to be high-quality and delicious while at the same time being an affordable product by utilizing his discerning skills as a fresh produce professional.

Market Creation

Believing that vertically farmed vegetables should not be limited to premium products, Spread tirelessly worked on innovating cultivation technology and improved its operations to make the products more affordable for a wider audience. With the need for convenience and awareness of health on the rise, Vegetus’s cumulative sales exceeded 100 million servings, and continue to grow. Overall, vertically farmed lettuce is now being sold in numerous supermarkets across Japan, and the market is expected to expand further, reaching 45 billion yen by 2026*1.

Commitment to Deliciousness and Safety

1. Indoor Cultivation
Spread is pursuing the deliciousness and texture of vegetables through a unique hydroponic cultivation method that has acquired multiple patents. Due to the cultivation space being a closed area, there is no need to worry about insects or weeds, and this makes it possible to produce vegetables in a pesticide-free manner. Creating an environment where plants can thrive makes for a better product, as the lettuce retains its original taste without the typical bitterness of outdoor lettuce, in addition to being rich in beta-carotene*2.

2. Safety and Quality Control
We grow vegetables in a hygienic environment that has acquired international certification standard under the GLOBALG.A.P. standard and JAS0012 certification for vertical farms, established by the Japanese Ministry of Agriculture, Forestry and Fisheries. In addition to hygiene measures such as zoning, wearing special sanitary clothing, thoroughly washing one’s hands, and removing dust and foreign matter using adhesive tape and air showers before entering the cultivation area, Spread also conducts sensory tests of the produce to ensure only high quality vegetables are delivered to the customers.

3. Product Development to Increase Added Value
In 2021, amidst growing awareness of sustainability, Spread launched a sustainable product “Chigiri” using leaves that are removed during the production process. This spring Spread started selling a new European lettuce variety, the first to be introduced in Japan, under the name of “Stick Lettuce”. We continue to develop products that meet the ever-changing lifestyles and needs of consumers.
