Nagasaki turned its sewers into an ecosystem. Not kidding. 🐠♻️

Some streets have open drainage channels so clean, koi fish swim through them.

No tricks. No filters. Just:
✅ Strict waste systems
✅ Community respect for nature
✅ Urban design that works with ecosystems—not against them

These “living sewers” aren’t just rare—they’re a vision.
Of what cities could be, when we take care of what’s beneath our feet.
