Japanese? [επιλυμένο]

I am hoping somebody can identify this coin. It's a lovely looking coin and I'm trying to find out as much about it as possible. I'm slowly reading up more on Asian coins, but I have a long way to go. Any help would be greatly welcome.

 

You're correct, it's Japanese: N#5434

The date should be on the other side.

Thank you very much. I really do appreciate it. Everyday I'm learning something new, and that's why I love looking at all world coins and their history (especially Asian coins). I'm going through boxes and boxes of different world coins. One day I am going to have to sell some!

I need to do more research on the whole area. But again thanks. I only ask when I get stuck (although this seems a quite common coin). However, it's really beautiful. 

Cheers,

phil

After a second check, I've just realised that it might be this one either: N#13954

The reverse is the same, but the era name should be visible on the obverse.

Many thanks once again. These designs are so beautiful (in my opinion). This whole area is fascinating. I really need to get over there at some point.

Many regards,

Phil
