Born from the Hachiro Lagoon reclamation, Ogata Village is surrounded by a 51.5km long embankment. Acting as the town’s lifeline, this bank took six years to build, beginning in 1958. A post marks the final construction point, 1.4km east of the Nanbu Drain Pumping Station. Construction was finished on October 12th, 1963 and drainage inside the embankment began a month later on November 12th.
