The Hanase Bypass Waterway (KS: 話せ迂回水路, Hanase Ukaisuiro) is an artificially constructed diversionary waterway in Komashi, between the realms of Yukino and Maikaze. Constructed between 1955 to 1965 to properly mitigate the discharge of the Yukino River after the 1949 Central Komashi floods, the Hanase Bypass Waterway forms, and is an integral part of the Yukino River Counterflooding System, to control the flow of the Yukino during heavy rains and storms and avoid flooding of the lower Central Komashi floodplain.
The colossal waterway and the flood countering system was conceptualized shortly after a catastrophic storm in 1949 that passed over Komashi that burst the banks of the river's source high up in the Wakashi Springs, causing a major flood that inundated most of the lower Central Komashi floodplain, and caused major damage in Yukino KDK. Construction began in 1955, set exactly six years after the disaster, and was completed in 1965.
