The only form of region protection on the Super Nintendo is physical. Carts from japan will not fit in US consoles and vice versa. To play Super Famicom carts on a US console, you need to remove two plastic tabs on the inside of the cart slot.
To remove, it is suggested you use plastic model clippers, readily available at hobby stores.
