Thank you notes get a "sweet" upgrade with Tokyo Super Sweets' Arigachoco. Based on a fusion of the Japanese word for "thank you" (arigato) and "chocolate," these chocolates (green tea-flavored, enrobed in a white chocolate coating) come with a QR code on the box. Scan the code with your cell phone and you'll receive a message of thanks that the sender picked for you (all ending cutely with "Arigachoco!"). Saves you from buying all that unnecessary stationery, eh? [via Trends in Japan]
