The current flag of Japanese quarantine is a yellow over blue bi-color flag
and blue "Q" on upper hoist. The flag was adopted 16 June 1954. The yellow is an
international color for quarantine and blue stands for sea and sky. "Q" is of course
the initial for quarantine.

Between August 1, 1921 and April 8, 1948: The blue over yellow (not yellow over blue) bi-color flag was used. The flag did not have a "Q".

Redrawn to get standard size and get rid of dithering. I've kept more or less
to the yellow and blue shades used, assuming there was a reason for those
shades. If so, we might want to give that reason/source. Otherwise, I could draw
a version with standard blue and yellow instead.
