The market awakens long before most of Tokyo stirs. By 3 AM, trucks have already delivered their precious cargo from ports across Japan. At the entrance, weathered wooden signs and lanterns hang above narrow passageways, marking the threshold between ordinary Tokyo and this parallel universe of commerce. The alleyways seem to inhale as the first vendors arrive, exhaling steam from early morning tea and broth. Follow the most purposeful walkers—they know where they’re going—and listen for the first calls between old friends who see each other only in these blue hours before dawn.
