Unused Tokyo tunnel gets new life as underground veggie farm

Stable temperatures cut electricity bills by two-thirds at automated plant

It is hoped the fully automated underground farm in Chiba Prefecture will be able to produce 5,000 vegetables a day.

Conveyor manufacturer Itoh Denki and electronics maker Fujitsu have set up an automated underground vegetable farm in a disused utility tunnel in Chiba Prefecture, just east of the Japanese capital.
