Fukuoka Weir

Overview

The Fukuoka Weir is a weir on the Ko-gai River located in Kitayama, Tsukuba Mirai City, Ibaraki Prefecture. It was constructed in 1625 (Kan'ei 2) by Tadaharu Ina, the Kanto Gun-dai (regional governor), as an irrigation waterway accompanying the new paddy field development during the Genna era. Initially called the Yamada-numa Weir, it was relocated to Fukuoka (present-day Kitayama) in 1722 (Hyoho 7) and renamed the Fukuoka Weir. It was rebuilt in wood in 1886 (Meiji 19), in reinforced concrete in 1923 (Taisho 12), and again in 1971 (Showa 46) due to increased river flow and aging. With a water storage capacity of 2.75 million tons, it continues to serve as a water source for the downstream rice paddies. Along the embankment of the waterway flowing between the Ko-gai River and the weir, approximately 550 cherry trees (Someiyoshino) stretch for 1.8km, creating a stunning cherry blossom spectacle. A promenade and multi-purpose plaza have been developed, and in March 2006, the "Fukuoka Weir Sakura Park" was also established. In 2006, it was selected as one of the "100 Best Irrigation Canals" by the Ministry of Agriculture, Forestry and Fisheries. The Fukuoka Weir is one of the three major weirs in the Kanto region and is also designated as one of the "100 Ibaraki Sightseeing Spots" and "100 Ibaraki Landscapes". The breathtaking cherry blossom tunnel that stretches approximately 1.8km in spring draws numerous cherry blossom viewers from across Ibaraki and beyond. The "Fukuoka Weir Sakura Festival" is held during the cherry blossom season. During the festival's weekend days, a temporary stage is set up in the heart of the cherry blossom lined area, hosting various events, local product sales, and food stalls. The embankment with its cherry blossom tunnel offers a promenade and multi-purpose plaza, making it a relaxing place for those enjoying strolls and fishing.
