AN
It is a fully artificial light type plant factory using an agricultural greenhouse.This system allows planted seedlings to grow while automatically circulating in the cultivation room, and allows workers to harvest without entering the cultivation room, therefore reducing the risk of contamination by foreign matter and the burden on the workers.

Your existing agricultural greenhouses can be used. It is also possible to construct a plant factory using farmland.The inside of the greenhouse can be automatically controlled to provide an optimal growing environment for lettuce, allowing for stable and safe cultivation.

Possible to cultivate large, thick, crispy, high quality lettuce in a stable condition. Suitable for commercial use, cut vegetables, etc. Cultivation of lettuce such as frill lettuce, batavia lettuce, and romaine lettuce is possible.
AN Cultivation performance
High value-added, high quality and the needs of large demand customers can be realized at the same time.

Contribution to SDGs




※The values of conventional fully artificial lightvtype plant factory were estimated on the basis of actual results from the test farms of our group companies or our own test farms.
※The CO2 values were estimated from our CO2 emission coefficient of 0.441 kg-CO2/kWh in FY2020 published by TEPCO Energy Partner, based on the amount of electricity consumed.
※The figures given are based on cultivation cases and are not guaranteed values.
Handling of processed products, Measurement bacteria counts
Measurement bacteria counts are implemented
Six varieties (3 cultivation methods x 2 varieties) were processed and tested using the following procedures


Inspection Summary
Varieties | Frilled lettuce, Leaf lettuce |
Cultivation method | Cultivation in AN system, outdoor cultivation, cultivation in other plant factories |
Number of Samples | 120 *3 cultivation methods, 2 varieties 6 x 20 |
Bacteria count inspection company | Ikari Sterilization Co. |
Bacteria count method | General viable bacteria count standardized observation plate method (mixed culture method) |
Lettuce to be tested is cut, sterilized and washed (once), dehydrated, weighed, filled, and gas displacement packaged to prepare samples. After packaging, the samples are stored refrigerated at 5°C. The testing period was from the day after the packaging date to 10 days later, and a total of five tests were conducted.

※1 There is almost no variation in the number of bacteria depends on passage of time.
※2 There are variations in the number of bacteria depending on the samples.
Difficult to maintain consistent quality.
Additional sterilization washing frequency and time are necessary to reduce variation in the number of bacteria.
