In 2015 there were several Japanese prefectural stamp issues celebrating the 60th anniversary of “Local Government Law”, two of which contained images of lighthouses. Each of the issues consisted of a sheet of five stamps.
The Tokushima Prefecture issue of 2 Jun 2015 shows a sea turtle on Ohama Beach, just north of the small port of Minami. At the upper right of the stamp is a tiny red dot that is Hiwasa Kō north breakwater light.
The 8 Dec 2015 issue of Chiba Prefecture shows, much more clearly, Inubō Saki Lighthouse. Inubō Saki was built in 1874 and was designed by the Scottish lighthouse engineer Richard Henry Brunton.
