Two Japan Stamps. What Are These Cancels?

Hello! Any help with these cancels would be greatly appreciated! Thanks.

Fiscal ?

They look to be 1-sen and 2-sen revenues from one or another series starting in 1898, so revenue cancels would be expected.

Thank you for the input, gentlemen! For the second stamp, I typed "Kamitaki" in google and it came back with a mountain range and also a Hawaii name origin. Can't really find much info on this cancel anywhere. I just started going through my Japan stamps. Very neat colors and designs.

As the others have said, these are revenues. The red cancel in the first one is a "chop" or seal, with the characters for the last name of the person who cancelled it. I don't know this authoritatively, but usually that means it was some kind of government employee who did it.

The cancel on the second stamp I'm pretty sure would be a business' cancel, probably to cancel a tax stamp that had to be paid on certain kinds of merchandise. The stamp might originally have been placed on a receipt, bill of sale, etc.

Hope that's helpful!

The first does indeed have part of a personal seal. I can make out 'Yama' as the first character, but I'm not sure about the second. The whole seal possibly reads 'Yamada'.

The second stamp also does have a company seal on it: the Japanese appears to read something like 'Kamitaki Trading Company' with 'Yokohama' above it.
