I bought a Shamisen but the fujaku doesn't seem to fit well


I recently bought a shamisen (Greetings from Costa Rica!)
The problem is the fujaku, it doesn’t fit well, I tried to play a tab on one of Kyle videos and still wrong, and I put the fujaku exactly how Kyle told us!

In need a lil of help, I think is the shamisen, it looks like a Nagauta instead of a tsugaru ¿It would be that?

If you have a digital tuner you can always use painter’s tape to make your own markings.
