I emerge from the Tokyo Monorail station on Shōwajima, a small island in Tokyo Bay that’s nestled between downtown Tokyo and Haneda Airport. Disoriented and dodging cargo trucks exiting a busy overpass, I duck under a bridge and consult the map on my phone, which leads me deeper into a warren of warehouses. I eventually find Espec Mic Corp.’s VegetaFarm, in a dilapidated 1960s office building tucked between a printing plant and a beer distributor. Stepping inside the glass-walled lobby on the second floor, I see racks upon racks of leafy green lettuce and kale growing in hydroponic solutions of water and a precisely calibrated mix of nutrients. Energy-efficient LEDs emit a pinkish light within a spectral range of 400 to 700 nanometers, the sweet spot for photosynthesis.
