This wasn't a difficult find; I traveled mentally to the small southernmost main island of the Japanese archipelago, Kyushu, and looked for lighthouses. The one I found was the southernmost, and also notable because it has a symmetrical volcano nearby (Kaimondake, last erupted in 885 AD) that shows up in some of the pictures.
The short name of the lighthouse is Nagasakibana; the long name is Satsuma Nagasaki Hana. It isn't a very big lighthouse, and it's not one that is accessible from the inside. What it lacks in size it makes up for in a picturesque location, as you'll see.
Here's a short descriptive excerpt from The Lighthouse Directory:
"1957. Active; focal plane 21 m (69 ft); white light, 3 s on, 3 s off. 11 m (36 ft) round concrete tower attached to a square 1-story concrete equipment room. Entire lighthouse is white. The base of the lighthouse has been developed as a public observation deck, with a circular roof to provide shelter and a broad stairway leading down to the beach."
And the pictures I found. There are a lot of stock (professional) pictures available of this lighthouse too, but I don't feature those.
