Where can I learn Akita Nikata Bushi?

Does anyone know where I can learn to play this song?

Well i got that score from the Nitta Ryu Volume 1
If you’re outside Japan you can get that book from the Bachido store, as well i would recommend you to check the lessons on the Bachido school, it might be there as well

Sadly, they don’t have the lesson for the song :C but they do have a book with notations! Yay! Thanks thanks!
