I am collaborating with the YouTube channel "Girl Crazy For J-pop Culutre". I send her lists of my top artists from Japan and she makes a video for me and uploads it to her channel. These videos looking awesome and I am happy I can share my favorite artists through them. Here are the ones she already uploaded for me.
