The Japan Times reports that companies are applying AI and sensor technology to indoor farming in Japan and related operations abroad. Oishii Farm has opened a research and development base in Hamura, western Tokyo, where it plans to develop indoor cultivation methods for crops including tomatoes, as well as robots for planting and packaging. The company also uses AI to manage the breeding environment for bees used to pollinate strawberries, and says its pollination rate has reached 95%.
The Japan Times reports that Oishii Farm, which operates a strawberry factory in the United States, recently established a research and development base in Hamura in western Tokyo. The company plans to study efficient ways to grow additional crops indoors, including tomatoes, and to develop robots that can plant and package produce automatically. The article does not say that these robots are already operating commercially, and it provides no timeline for deployment or information about their technical design.
The report says Oishii Farm uses AI to manage the breeding environment for bees, which are needed to pollinate its strawberries. Hiroki Koga, the company’s co-founder and chief executive, told The Japan Times that the technology had raised the pollination rate for the company’s strawberries to 95%. The article does not describe the system’s inputs, model, control process, baseline measurement or independent verification of that figure. Koga also characterized indoor plant factories as a way to avoid seasonal and weather-related constraints.
The Japan Times also reports that NTT East and other companies began an aquaponics test in Tokyo in June. The project combines Japanese nishikigoi ornamental carp with the cultivation of ginseng. According to the article, AI and sensors control lighting and temperature, and the project has reduced the period before shipment from years in conventional outdoor farming to months. NTT East said fish feces are used as fertilizer instead of agricultural chemicals, allowing leaves and stems that were previously discarded to be used for business purposes. The source does not provide crop yields, operating costs or independent confirmation of the results.

The report places these projects against a sharp decline in Japan’s agricultural workforce. According to figures cited by The Japan Times from the agriculture ministry, the number of farmers whose primary income comes from agriculture fell from about 2.05 million in 2010 to about 980,000 in 2026. Indoor farming may reduce dependence on seasonal conditions and labor, but the report also shows that automation does not by itself resolve the sector’s financial pressures.
Japan’s labor shortage gives the projects a concrete public rationale. The Japan Times cites agriculture ministry figures showing that the number of farmers whose primary source of income is agriculture declined from roughly 2.05 million in 2010 to about 980,000 in 2026. A smaller workforce creates pressure to maintain production with fewer workers, and indoor facilities can potentially make growing conditions more controllable. Those implications follow from the labor figures and projects described in the report, but the article does not quantify how many jobs the systems could replace or create.
The reported applications also illustrate that AI in agriculture may be most consequential when paired with physical infrastructure and biological processes. In the Oishii Farm example, AI is described as managing an environment for bees rather than producing a standalone digital service. In the NTT East project, AI and sensors are described as controlling environmental conditions in an aquaponics system. That makes the reliability of sensors, control settings, equipment maintenance and biological conditions as important as the software itself.
The economic case remains uncertain. The Japanese government is encouraging participation from other industries and advanced-technology adoption, and has set a target of ¥4.6 trillion in public and private investment in plant factories by fiscal 2040, The Japan Times reports. Japan has about 440 plant factories, up 40% from a decade ago, according to the article. But the report also notes that some operators have gone bankrupt after failing to recover their initial costs. A plant-factory manager cited by the newspaper said profitability can remain difficult even when worker numbers fall if capital and electricity expenses rise.

The key questions are whether these systems can produce dependable returns after accounting for construction, equipment and electricity, and whether reported gains can be reproduced beyond the individual projects described. The source does not provide model names, technical specifications, independent testing or detailed cost data. It also does not establish that AI alone caused the reported improvements.
The first issue to watch is whether the reported performance improvements translate into sustainable businesses. The source gives a 95% pollination rate for Oishii Farm and a reduction from years to months in the NTT East aquaponics test, but it does not disclose the comparison methods, sample sizes, duration of testing or financial results. Independent evaluation would be needed to determine whether these outcomes persist across crops, facilities and seasons.
The next issue is commercialization. Oishii Farm’s plans for tomatoes and automated planting and packaging are described as development objectives, not confirmed product launches. The NTT East project is identified as a test. Follow-up reporting could establish whether either effort expands, reaches routine operation, or changes its technical approach. It could also clarify how much work remains dependent on human operators.
Costs and resource use will be central. Indoor farms can reduce exposure to weather and may allow tighter control of growing conditions, but the report identifies high initial spending and electricity costs as major risks. The source does not provide energy consumption, capital budgets, crop prices, labor savings or emissions data. Those unknowns limit any conclusion about whether AI-enabled indoor farming is broadly more efficient or profitable than conventional agriculture. The claims in this assessment are based on The Japan Times report and have not been independently confirmed from public primary documents supplied here.
