Does anyone know how Tabelog and Asku, the two major internet driven user websites in Japan, determine the rating and ranking of the restaurants?
I am just wondering the type of demographic that led to very different conclusion for Tokyo area by the two groups. Is it due to income group, gender, occupation, geographic or anything specific?
For example, in Sushi, Sushi Mizutani (ranked no. 2), Kanesaka (ranked no.9) in Tabelog is nowhere to be found in the top 30 in Asku. No.1 ranked Sushi Nakahisa in Asku is nowhere to be found in the top 20 list in Tabelog. There are only 2-3 common names in the top 20 of both list.
It is the same with 日本料理 category, no.1 ranked 京味 (in Tabelog) is not in the top 30 list of AskU while the no.3 ranked Kitcho (in AskU) is not in Tabelog at all. At a glance, only 3-4 names share the top 20 list in both sites.
I notice most "best" lists in major cities are usually quite similar, even if the rating companies are competitors. So I am interested to know why it is different in this case. Would appreciate any feedback on this issue.
