Are the any other places to find some shamisen notations?

Hello! As the title states, i’m wondering if there are any other places to find notations besides Bachido. It’s not like I don’t have enough, but more that they’re all tsugaru pieces, and I want to learn some less-tsugaru-ey pieces. (Yoshida brother’s Namonoki Oka is one that comes to mind)
For example, I also play guitar. So whenever I feel like trying to learn a new song I can search up for some tabs and 9 times out of 10 I can find some for the song I want to learn. However for shamisen, it just doesn’t happen. I’m assuming it’s because I live in the Americas where the shamisen is a very, very foreign instrument, and i’m sure next to no one plays it here.
In short, if any one know of some place on the internet where I can get some more notations, and particularly for the aforementioned Namoki Oka, please let me know.
