Takoa,
It's no wonder that the Japanese are regarded so highly in the manufacture of so many things including bicycles. The Japanese hollow rivets must have been introduced to save weight! No doubt the best ones were double butted for extra strength and even lower weight. Remarkable, your find. You must treasure it, I would naturally.
I have no affiliation with the US Postal Team that I am aware of.

the part of rivet(or nail) was cut off by a screw driver , broken
part of the rivet remained inside might prevent the rivet from
coming off. Or because the rivet( nail) was a little tapered at
the top , when he drove it into the hole by hammer ,the paint
involved might help the fixing. ( I hope you can understand my
awkward explanation)
In Japan I usually saw headbadges were fixed by hollow( tube)
brass rivets which made the frame cheap. On the contrary I saw on
Italian frames solid copper or brass rivets ( nails) . Were the
hollow brass rivets peculiar to Japan?
And are "self-tapping" rivets Chuck Schmidt mentioned short
enough to make it unnecessary to cut off the part inside?
