Jap's eye
The external opening of the male urethra, appearing as a slit at the end of the penis. Perceived by Europeans to resemble the eye of a Japanese man, some consider the term racist, but it clearly isn't, because Japanese men have them too.
Takahiro's attempts to find medical attention for the burning sensation in his Jap's eye were initially thwarted when he was directed to an optometrist.
