In case you missed the latest installment of Japanese audience
ratings from Siegel Clyne, it appears that Mononoke is pulling some impressive numbers. Here's a sampling of the results:
*4.8% (*3.5%) 09/14 (Fri) 12:45am-*1:15am Fuji TV Mononoke
*3.6% (**.*%) 09/16 (Sun) *8:30am-*9:00am TV Tokyo Tengen Toppa Gurren Lagann
*3.3% (*3.1%) 09/13 (Thu) *6:00pm-*6:30pm TV Tokyo Gintama
*3.1% (*3.0%) 09/12 (Wed) *7:26pm-*7:55pm TV Tokyo BLEACH
*3.1% (**.*%) 09/16 (Sun) 10:00am-10:30am TV Tokyo Hayate no Gotoku! [Hayate the Combat Butler]
*2.8% (*2.9%) 09/12 (Wed) *7:00pm-*7:26pm TV Tokyo Eyeshield 21
*2.7% (*2.2%) 09/12 (Wed) *1:26am-25:56am NTV Claymore
I'm not sure exactly which episode aired on 9/14, perhaps the final one? Even allowing for a little extra buzz at the end of the series, the 3.5 average places Mononoke ahead of a lot of other fairly popular shows. If we tried to estimate these ratings based on the number of AS postings a show receives, we'd certainly get the wrong answer if we were comparing Mononoke to Claymore.
I'd be curious to see the demographics for this show; I'd guess the audience skews older than the viewership for something like Tengen Toppa Gurren Lagann, but I'm obviously just taking shots in the dark here.
