Thinking on this - just a quick note - how about transportation and
range extension:

Egg clusters floating - even those attached - ripped up by a storm.
Then the ocean stream tugs it from the south pacific up the Japanese
current and drops some off here and there.

Typhoons, hurricanes help rip and transport as well.

While on Kwajalein - we had both bird and airplane caught in winds
and came in for landings.
And some of the 'crane' like 'stork' water walking birds might
transport eggs on their feet/legs.   Boats in lakes do that as well.

Naturally is nature way, not man doing it on purpose.
