so after searching 4 Japanese markets, I finally found my natchan! there was only 1 flavor too... lemon grapefruit.
it's goooood!!!!!! It reminds me of squirt, but without the carbonation.
this is the cap on the natchan. Dan had the awesome idea of making it into a keychain. I think i'm going to make it into something to hang in my car. kawaii, ne?
