For those of you who shop at Tokyo Midtown, let me warn you against the absolutely silly prices at Noka Chocolate.
Dallasfood.org did a long (11-part) and detailed expose on Noka Chocolate, their claims, and it's clear that the chocolate is not worth what they charge and Tokyo Midtown did not do any due-diligence before selecting this chocolate marketing company. The most recent news from DallasFood.org is how Noka is using Nikkei's US English newspaper to make claims in Japan that are clearly misleading: Noka and the Nikkei.
Rich Japanese customers don't know any better, sadly.
