Nikkei overbilled two advertisers after inflating ad booklet's circulation

ITmedia News reported on 17 September that the publisher of the Nikkei, Japan's largest business daily, told two advertisers that the advertising booklet "THE NIKKEI MAGAZINE" was distributed in more copies than was actually the case. The booklet is inserted into the morning edition of the paper. On the strength of those inflated numbers, the two advertisers were billed more than they should have been, by tens of millions of yen in total.

Advertising rates in Japanese print rest on circulation figures that publishers report themselves. The Nikkei's own readership numbers are widely treated as a marker of who reads business news in Japan, and Japanese companies, foreign brands and agencies all use them when deciding where to spend. A booklet inserted into the morning paper is a sold product in its own right, with its own claimed reach, so an inflated count is not a rounding issue for the two buyers concerned; it is a question about what anyone buying that space was actually paying for.

What the report leaves open matters as much as what it states. It covers one booklet and two advertisers. It does not say whether the practice touched the newspaper's main circulation figures, other insert titles or other advertisers, nor whether Nikkei has acknowledged the overbilling, corrected the figures, refunded money or commissioned an outside check. The date is a single ITmedia item; no second outlet is cited here.
