The Seto Nakai, or Inland Sea, is dotted with islands and islets, and while many have now been connected by bridges to each other and the mainland, there are still dozens and dozens of small ferries plying the waters. These photos I took on the ferry from Kinoe on Osaki Kamijima Island to Takehara in Hiroshima. Shipbuilding and repair is still a major industry on many islands.
Most Japanese seem blissfully unaware of the incredible amounts of concrete that are poured in Japan compared to other countries.
The island with the two transmission towers on it is Okunoshima, now most famous as "Rabbit Island", less famous as the site of a WWII poison gas factory, and almost unkown as the home of the tallest electricity transmission tower in all of Japan.
Some of the smaller islands have become floating factories. Not sure what is being produced or processed here.
Of course small fishing boats continue to operate.....
