The NINKI ratings are the results of a POLL conducted by Oricon indicating degree of interest/degree of purchase intention in an upcoming release. Although the ratings are never a true reflection of sales, it does give a strong prediction about where the single/album will place in terms of popularity amongst the Japanese public. However, they are NOT an indication of how it will perform in terms of chart positioning and total sales for the week.
According to Oricon's note under the NINKI page, Oricon researches about 870,000 of its members by random sampling of 400 members in their 10s until 40s. 50 men and 50 women are chosen randomly to participate in each age group. (However, some popular artists have had NINKI exceeding 500, so we can only assume that Oricon has extended the polling to around 600/700 people now.)
The highest NINKI is less than 100, chances are the sales could be less than 100k as well. But...
A chance for YUI at number 1. Go YUI! Also, even if rating for DEEP is low, I hope they'll really get in the top 5 or top 10 at least.
And although Sukima Switch are no.1 on NINKI, I believe A.N.JELL will get no.1 seeing how they've been hanging around the top of Amazon daily chart since the announcement of the release. Also hoping that OOR will defy NINKI and get in the top 5! :)
Good luck to all!
