Tourist facilities around Jodogahama Beach were heavily damaged. After 3 years the seaside promenades have been replaced and improved and the sightseeing attractions fully reopened
New housing built on higher ground - some locals refuse to relocate, most are the elderly who cannot walk up and down the hills and want to be closer to the train station and stores
