Noritake and Tokuiten Conduct Joint Demonstration Experiment Utilizing Fine Bubble Technology in Agriculture: 27% Increase in Komatsuna Plant Weight, 31% Increase in Sugar Content, and Suppression of White Rust Disease Confirmed
Noritake and Tokuiten jointly conducted a demonstration experiment applying fine bubble technology to agriculture, successfully increasing komatsuna yield by 27%, sugar content by 31%, and suppressing white rust disease. This is a groundbreaking achievement contributing to addressing labor shortages and reducing environmental impact in agriculture.

Tokuiten Co., Ltd. (Headquarters: Nagoya, Aichi; Representative Director: Ryuichiro Toyokichi; hereinafter "Tokuiten") and Noritake Co., Limited (Headquarters: Nagoya, Aichi; Representative Director and President: Akira Higashiyama; hereinafter "Noritake") jointly conducted a demonstration experiment on komatsuna cultivation using Noritake's fine bubble generator "Cerapore" and compiled the results. This demonstration experiment was conducted from October 2025 to April 2026 at Tokuiten Lab Farm in Chita City, Aichi Prefecture, yielding results that contribute to yield, quality, and disease prevention in organic farming*1.
Background of the Demonstration Experiment
In the agricultural sector, against the backdrop of labor shortages and climate change issues, there is a demand for cultivation technologies that simultaneously achieve stable yields, improved quality, and reduced environmental impact. The Ministry of Agriculture, Forestry and Fisheries (MAFF) set a goal in its "Green Food System Strategy*2" formulated in 2021 to reduce the use of chemical pesticides by 50% by 2050. This has led to an increased need for disease prevention technologies that do not rely on chemical pesticides, while also demanding stable yields and improved quality. In this context, the utilization of fine bubbles is attracting attention as a new technology with low environmental impact.
Tokuiten has been utilizing Noritake's fine bubble generator, which uses porous ceramics, in cultivation since 2024 and has experienced its effects. However, there was a need for quantitative verification through systematic comparative experiments to clarify its effects. Against this background, Noritake, aiming to establish fine bubble technology in the agricultural sector, and Tokuiten, which emphasizes data-driven effect verification, found their directions aligned, leading to this joint demonstration experiment.
Results of the Demonstration Experiment
From October 2025, a joint demonstration experiment was conducted at Tokuiten Lab Farm in Chita City, Aichi Prefecture, focusing on komatsuna, which has a fast harvest cycle and allows for repeated testing in a short period, based on Tokuiten's organic farming practices, using Noritake's fine bubble generator "Cerapore"*3. One greenhouse was divided into nine sections, and by varying conditions, the following effectiveness was confirmed with two methods utilizing fine bubbles.
1. Yield Increase and Quality Improvement - Fine Bubble Irrigation (Gas type: Air)
In plots irrigated with agricultural water generating fine bubbles, the average weight increased by 27% compared to normal irrigation. Uniform growth promotion was confirmed in both above-ground and underground parts, with stem height +6% and root length +6%, suggesting that oxygen supply to the rhizosphere*4 contributed to the yield increase. Furthermore, significant improvements in taste were also confirmed, with sugar content increasing by 31% and bitterness components (nitrate ions) decreasing by 20%.
Comparison conditions: Sown in October 2025, autumn crop. Comparison based on the top 10 heaviest plants in the target plots.
2. Disease Prevention - Fine Bubble Mist (Gas type: Ozone)
In plots misted with ozone-infused fine bubbles, no white rust disease occurred (control plots without fine bubble mist had an incidence of 12.1%). This result could be a new option for disease prevention in reduced-pesticide cultivation.
Comparison conditions: Sown in December 2025, winter crop. Comparison between target plots.

Future Outlook
Based on the results obtained from this demonstration experiment, both companies will proceed with the following initiatives.
1. Continued Verification of Effects
Going forward, we plan to further verify practical cultivation conditions for yield increase and quality improvement through fine bubble irrigation (gas type: air) and disease prevention through fine bubble mist (gas type: ozone). Concurrently, we will also consider fine bubbles using different gas types such as CO2, and promote the establishment of this technology as one that contributes to further stabilization of yields, improvement of quality, and reduction of environmental impact through reduced pesticide use.
2. Demonstration Experiments with Other Crops
In addition to komatsuna, demonstration experiments to verify the effects of fine bubbles on other crops are planned. We will clarify the applicability to a wide range of crops and accumulate knowledge for their utilization.
3. Introduction to Tokuiten's New Farm
Tokuiten plans to introduce Noritake's fine bubble generator irrigation system in its new 1-hectare farm scheduled for construction in FY2026. Both companies will accumulate operational data in a larger environment and verify the effects at the practical stage.
