In the 19th century, Hiroshige Utagawa created "The Fifty-Three Stations of the Tokaido". The Tokaido Road is now National Route 1. Construction work on the Seisho Bypass on approximately 20 kilometres of coastline along National Route 1 between Oiso and Odawara in Kanagawa Prefecture has been ongoing since the 1960s. There is a section of the Seisho Bypass built on sand beaches that gives a panoramic view of Sagami Bay, symbol of Kanagawa Prefecture, from a car window. This photo series focuses on the area that extends underneath the bypass along the Seisho Coast and National Route 1. The Seisho Coast is usually a quiet place with few people around, familiar to locals as a fishing spot and a walking route for large dogs. At the same time, coastal erosion due to natural processes has progressed. Some areas have lost as much as 45 metres of sand beach in the last 65 years, and the seawater pools at Hiratsuka and Kozu have recently been closed. In the Ninomiya area, a typhoon washed away the beach and caused a section of the Seisho Bypass to collapse in 2007. Currently this area has an artificial sand beach. At Kozu the pier structure of the Seisho Bypass is being eroded by waves, and tetrapods are becoming increasingly common here. I decided to make a photographic record of the appearance of this coastal area that has been restored by humans. Another purpose of this photo series is to make a comparison between Hiroshige’s depiction of Hiratsuka, Oiso and Odawara in "The Fifty-Three Stations of the Tokaido", and how these three places look nowadays. This photo series is an ongoing project, which started in September 2018.
