I took this photo in August 1974 of this lighthouse structure sited somewhere in the middle of Tokyo Bay, which I recorded as being called the Tokyo Light (from the chart). The only record I can find now is a photo (without any text) of it, on pinterest.com, but the link it gives (https://www.ibiblio.org/lighthouse/jphn2a.htm) does not contain the photo or any information of “Tokyo Light”, so it seems that it no longer exists.
