I remember an old blog called konbini-life where this guy reviewed the strange stuff he bought at local konbinis (candies and other weird "barely" edible things). The blog is now dead (but was quite popular at the time, he was even featured in the Japan Times), you could try opening something similar, i would read it :) Also, yep, at the moment it's too soon for a/b test.
