The Higashiyama Water Supply Tower.

The Higashiyama Water Supply Tower was constructed in March of 1930 and was used as a water distribution tower to supply water to the Kakuozan area in Chikusa Ward for approximately 43 years until 1973. From 1979, it was repurposed as an emergency water supply facility for disaster response. Additionally, in 1983, an observation deck was added, allowing citizens to enjoy the panoramic view of the city.
*Please note that due to ongoing construction work, the tower is currently close.
