Japan: Underground vertical farm opens at Kyuden HQ Kyushu Electric Power's special subsidiary has launched an indoor hydroponic vegetable farm in the basement of the company's headquarters building in central Fukuoka. The facility, located on the fourth basement level, began operations in April and was opened to the media on June 22.
Using LED lighting and nutrient-rich water instead of soil or pesticides, the farm grows six varieties of leafy vegetables, including lettuce and kale. The vegetables are expected to be sold through supermarkets and other retailers across Fukuoka Prefecture.
Kyushu Electric said it plans to expand production capacity and create additional employment opportunities if demand grows.
Why this matters: For operators, this is a water-management story. The useful signal is that direct substrate measurements can help cut drain loss materially without giving up yield or fruit quality, which is exactly the kind of controllable efficiency gain a facility can build on.
Frequently Asked Questions
Why does substrate sensing matter in free-drain strawberry systems?
Because drain percentage tells a grower what already happened, while substrate moisture and EC data show root-zone conditions directly. That makes it easier to cut water loss without guessing.
What is the operator takeaway from this trial?
If the thresholds are understood well enough, growers can reduce drain water materially while protecting yield and fruit quality, which makes sensing an operational tool instead of a reporting tool.
