Help With Japan Cover

It seems to be from Japan, to Japan with a US #281, so I'm thinking that it was sent from a US embassy inside Japan.
Any info on the usage here?
Thank you.

That is some kind of duplex cancel on the stamp, which is a US cancel, not Japanese. Need to try to read it clearly.

The back mark is definitely Kobe, Japan, which would say "Hiogo" if it were a bit older.
The other two on the back MAY be Honolulu, but I'm pretty sure the date is 1901.
Have no idea what the front mark says. A town name possibly?

I think it was mailed in the US to an addressee in Japan.

I think it is postmarked Spreckelsville, which is on the island of Maui in current-day Hawaii.

My Japanese friends were surprised at the name, Matsumoto Keido on this letter, who was a samurai in the 1860's and one of the "3 Presidents" leading an army called Tenchu Gumi, a campaign to "Westernize Japan's Navy".
It was successful until a rival clan convinced the shogunate and Emperor to "Expel the Western Influence", thereby trapping and exterminating the Tenchu Gumi.
If they would have succeeded, Japan most likely would have been on our side during the World Wars.

The lower arc of the ring probably reads, "H.ISLS." and the killer probably reads "MAUI" but that's just an educated guess, as I don't recall seeing one.

Cjd I think you nailed it!!!

Postmarked and sent at Hawaii, Maui County, Spreckelsville (1884-1962). Back stamp is from Honolulu.

The address is really neat, in those days there were no numbers to specify an address, and clan names were very tight and not spread around the country.
The most specific the address gets is "Forest Village of (something or other)", to Matsumoto Keido.
My friends say that it's almost certainly the same Matsumoto Keido as the characters for "Keido" are very specific to his own.

Honolulu, I thought so! Thank you for that confirmation.
