It’s a typical Japanese fast food and it’s served in many fast food places in Japan. Ingredients can be a little hard to find, but just go your nearest Asian Market and I’m sure you can find some. It might be hard to find the dashi bonito, but its just these fish stock powder. I know fish stock can sound a little unusual, but it goes great with the dish! The ginger is not like the ones with sushi, its a bright red strong flavored one.
