"OYASAI FARM," an Urban AI Hydroponic Unit, Goes on Live Display at Tokyo Innovation Base in Yurakucho—Achieving a 52% Cut in Initial Investment and a 290% Increase in Production

On April 1, 2026, OYASAI FARM, the urban-type AI hydroponic cultivation unit of OYASAI Inc. (Fukuoka City; representative: Shunta Kunimura), began an actual-unit exhibition atTokyo Innovation Base（TiB）in Yurakucho, Tokyo. The exhibition period runs through May 31, 2026. The company is an agricultural startup founded in April 2025, taking on the challenge of solving urban agriculture's issues with a hydroponic cultivation unit it calls the world's smallest farm.

What is OYASAI FARM—AI camera × subscription so that even those with no farming experience can grow

OYASAI FARM is an indoor cultivation system that combines an AI camera with a pesticide-free hydroponic cultivation unit. What is distinctive is a business model of a subscription of high-quality seedlings plus remote AI support, aiming for a setup where even supermarkets, restaurants, welfare facilities, and offices without agricultural knowledge can grow just by plugging in.

The appeal points on the numerical front are the following three.

The claim of raising production volume about threefold while holding the high initial cost that was the greatest bottleneck of plant factories to less than half brings a new axis into the debate on the economics of urban agriculture.

What the exhibition at Tokyo Innovation Base means

Tokyo Innovation Base (TiB) is a startup support base operated by the Tokyo Metropolitan Government, located in the Marunouchi area. Exhibiting at the facility is limited to companies that have passed a pitch screening, showing that OYASAI FARM was evaluated on the three axes of cost efficiency, social impact, and scalability.

At the exhibition, visitors can view an actually operating cultivation unit, and individual consultations and on-site visits are handled for businesses considering adoption. Assuming diverse installation sites such as supermarkets, restaurants, hotels, welfare facilities, and offices, the aim is to make it function not merely as a technology exhibition but also as a place for business talks.

Agriculture × welfare × food-loss reduction—a design that solves multiple issues at once

The social impact OYASAI FARM cited as TiB's pitch selection criteria spans four areas: support for agriculture-welfare collaboration, urban food self-sufficiency, food-loss reduction, and carbon reduction.

What draws particular attention is the point of contact with food loss.In a survey of 78 food businesses conducted by Kuradashi, high prices and logistics constraints have emerged as new factors increasing food loss. As distribution costs from growing region to consumption area rise, positioning an urban-type hydroponic cultivation unit as a small-to-medium-scale production base in the consumption area holds the potential to structurally reduce transport loss.

Meanwhile, the CO2-reduction effect from pesticide-free, indoor cultivation can also be a motive for adoption by offices and hotels, in that it is easy to incorporate into corporate sustainability reporting (ESG, Scope 3).

The democratization of plant factories shown by the world's smallest farm

Japan's plant-factory market has seen a run of withdrawals and downsizing over the past several years, as construction costs for large facilities, surging electricity costs, and profitability issues have piled up. The approach OYASAI FARM advocates—small, low-cost, AI remote support—can be called a design philosophy that turns this issue on its head.

Hydroponic cultivation that would not have been viable without a large-scale factory has its initial barrier lowered by a subscription-billing model, and AI fills the operational knowledge gap—this trinity structure is close in concept to a SaaS-type agricultural platform.

The company was only established in April 2025, but its appearance on the main stage of TiB is an opportunity to expand its points of contact with investors, major distributors, and local governments all at once. The three points to watch in future developments are likely: (1) expanding the range of items in the seedling subscription, (2) disclosing the yield-prediction accuracy of the AI camera, and (3) concretizing the agriculture-welfare collaboration scheme.

The agriture editorial team's perspective

Urban agriculture is shifting in positioning from hobby and CSR to food security, food-loss measures, and ESG procurement. If small, AI-type units like OYASAI FARM spread to commercial and welfare facilities, the distance between production and consumption will shrink, and combined withthe circular use of domestic fertilizer, it could become the seed of a new supply chain in which cities and rural areas exchange resources and food bidirectionally.

If third-party verification data backing up the figures of halving initial investment and tripling production volume is disclosed in the future, the acceleration of adoption will increase further. It is well worth considering having an opportunity for a visit or business talk during the exhibition period through May 31, 2026.
