Japan 1700-1800 - help identify

Hello! I tried to identify this coin myself, but with Japanese script it's “mission impossible”. The reverse is blank. 

W 3.1g, D 24mm, T<1mm

N#142546  maybe 

 Or these, with that blank reverse 

N#283929 

N#121450 

 Perhaps this, with a better character on the left 

N#121454 

Thank you ZacUK for the effort! However, each of these coins has a lot of different year-lines and Japanese letters, as printed in the catalogue, are quite different from the script used on the coin so I am not any closer to identifying the correct one 😒
