As Tokyo modernized into a sprawling metropolis, many of its historic waterways were paved over and culverted beneath concrete and asphalt. In the peaceful Hatsudai neighborhood, a lost tributary of the Udagawa River reveals itself through the curious, knee-high stone railings of the former Hatsudai Bridge straddling a quiet residential alley. For urban explorers and enthusiasts of Tokyo's hidden ankyo (underground waterways), this modest historic marker offers a charming and tangible glimpse into the city's vanished aquatic past.
