Hand Campus Shinjuku Advertises ¥2,980. I Read 90 Customer Receipts and the Median Was ¥7,980.
A Kabukicho onakura sells itself on ¥2,980 and prints 'there are no additional charges whatsoever' as the last row of its additional-charges table. Ninety customers on the same listing volunteered what they actually handed over: median ¥7,980, mean ¥8,866, exactly two of ninety at the advertised number. A forensic read of how a 43-line option menu, an invisible rank tier, and a single ¥1,000 discount denomination turn a floor price into a marketing figure.
