Selected 100 ReservoirTone Canal Project aimed at water intake from Tone River and supplying irrigation water to the middle reaches of Tone River basin areas, which had unstable water supply and also coping with the increasing water demand in Metropolitan Tokyo, which were challenging the success of Tokyo Olympics and related events at that time. The project started in November 1963 and completed in March 1968. So this year we are going to have 50th anniversary.

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 crucialfactor. 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 Mounds
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. Adjacent to some of the mounds, there is Museum of The Sakitama Ancient Burial Mounds, where some of the discoveries from the mounds are on display. A famous discovery is the sword with letters engraved. This engraving depicts the year of 471A.D., supposedly the oldest sword excavated from the ruin.
