Details Musashi Canal is an important water related facility that supplies urban water and river purification water to the metropolitan area, and drains inland water in the area around the canal. Due to the aging of Musashi Canal, reconstruction work was carried out to reinforce the canal facilities. During the reconstruction work, it was necessary to conduct the work while supplying urban water. Therefore, "halfway river cutoff method" was applied. In this method, the steel sheet piles for cut-off wall were installed near the center of the existing canal, and reconstructed respective cross section of the canal while switching the water flow.

Minuma Dai Canal Motoiri Park
Minuma Dai Canal Motoiri ParkMinuma Dai Canal Motoiri Park was constructed in 1977 in memory of Yasobei Izawa, the developer of Minuma Dai Canal in 1828. Within a short period of time this canal was completed, extending for 80km. In Edo period, rice was the staple food and the richness of the feudal lord's territory was measured by the amount of rice harvest. As it was an urgent need for the Tokugawa Shogunate Government to increase the rice harvest and for that purpose, water supply for irrigation of the rice field was a cruial factor. So 8th Shogun Yoshimume ordered Mr. Izawa to build the canal rather urgently. To answer to this order, he constructed this canal, which contributed to the huge expansion of rice fields in Kanto Plain.

Sakitama Ancient Burial MoundsMany burial mounds of the heads of the region were built from 5th through 7th century in Japan. What is unique to this ground is that there are eight such ancient burial mounds scattered around rather small area in the flat land somewhat away from a large river. Ajacent to some of the mounds, there is Musium of The Sakitama Ancient Burial Mounds, where some of the discoveries from the mounds are on display. A famous dicovery is the sword with letters engraved. This engraving dipicts the year of 471A.D., supposedly the oldest sword excavated from the ruin.
