asian trinket?

[MT Hunter]

an acquaintance of mine has this trinket and has no idea what it is...i told her i would ask here cuz if anyone can tell me it will be this group
the star shape with the numbers 1-31 spins around. it is about the size of a nickel and seems to be made of brass...not sure tho. she has it in a cardboard flip now and in fortunately i didn't get to take it home.
any ideas?

thanks

Japanese?

Japanese.

I don't know how much this helps. Toroku is Registration, as in registering something with a government office. The other word might be a name. Could be Y. Isho.

I think I understand the other side. It's simply a sort of perpetual calendar. The five points point to the eighth number after the previous point, so you can set one point on the date of any day of the week and find the date of the same weekday for the whole month.

Maybe it's a company giveaway trinket. Maybe for a company called Yisho Incorporated or Registered.

Was it worn on a chain? Can't tell from the photo.

Also, the 1485? Serial #?

yea there is a hole on the end that looks like it would be worn on a chain

day of the month counter--- you set it via the fist day of the first day of the monrh --then by checking it you can see that the 31st of the month will be (mon,tues, wed ,ect) --- day of the week .

The Japanese characters do say Yisho Toroku, which means registered name, like a patent. I tried to search for patent No 1485, but nothing. Seems a very low number for a patent. Clueless as to the front - as suggested sounds like the days of the month.

If it is Japanese, wouldnt the numbers also be written in Japanese? What does it say above 1485?
