Berry, Shibuya — The ¥29,000 Trial Course Is First-Visit Only, and It's the Worst Rate in the Building

Shibuya's Berry reserves its cheapest ticket — ¥29,000 for sixty minutes — for first visits only, then excludes that exact course from its ¥10,000 new-customer coupon. Run the per-minute math across all four classes and the trial course turns out to be the worst rate on the Regular ladder, while the best rate on the entire board belongs to a first-timer spending ¥45,000.

BBW Okubo: Nine Courses Built From One Ladder, and the ¥1,000 Upgrade That Buys the Cheapest Minutes in the Building

BBW in Shin-Okubo publishes nine separate course families across eight durations, and every one of them is the base delivery price plus a flat constant — doubled, plus ¥1,000, plus ¥3,000, plus ¥4,000. Run the offsets and the shop's real product becomes visible: the ¥1,000 soku-toku upgrade hands you fifteen minutes worth ¥3,000, and one cell in a seventy-two-cell grid breaks the pattern by exactly a thousand yen.

Aromajenne Shinagawa: Every Number on the Board Is a Multiple of ¥1,100, and the Cheapest Half Hour in the Shop Is the One Between 90 and 120

Aromajenne Shinagawa is an outcall men's esthetic running noon to 5 a.m. across the Gotanda-Shinagawa corridor, with a 33-therapist roster and two menus. Convert its price board into ¥1,100 units and the ladder stops being a ladder: the discount lives inside one 30-minute window at 120 minutes, and every course above it — including the six-, twelve- and twenty-four-hour options — costs more per minute, not less.

Shinjuku Thank You at 1 a.m.: The ¥2,000 That Turns Nine Acts Into a Hundred

A late-night booking at Shinjuku Thank You, the Kabukicho gekiyasu deriheru whose brand name is its own base rate. The ¥3,900 door is not the decision — the ¥2,000 nomination fee is, because it is the only thing standing between a nine-item basic menu and roughly a hundred free options, and its cost as a percentage swings from 51% to 7% depending purely on how long you book.

Puyo Station Kamata — ¥9,000 for Sixty, and the Pocchari Genre Nobody Explains to Visitors

Puyo Station Kamata is a pocchari (curvy) specialist deriheru in Ota Ward, open 10am to 5am every day of the year, with a posted rate of ¥9,000 for sixty minutes and a first-timer coupon giving seventy for the same money. It's one branch of a 24-location chain, and the way it prices options — a long list free, a short list paid — tells you more about the shop than the catchphrase does. Here's how to read it.

BIG TITS Shinjuku: The Shop Is Named After the Wrong Thing, and the Option Sheet Proves It

BIG TITS is a Shinjuku deriheru that leads with F-cups and I-cups, but its posted price sheet tells a different story — two free options, twenty-eight paid ones, and a base course that already includes what most shops bill for. It also publishes a ward-by-ward transport table and prints 'expat OK — ¥0' as a line item. Here's how to read the whole thing before you dial.

Kinshicho Mrs Aroma (Yumeoto): ¥200 a Minute Is the Real Price, and Everything Else on the Board Is a Fine for Deviating

Kinshicho Mrs Aroma is a Yumeoto-group mature-woman outcall aroma esthetic running 10:00 to 4:00 the next morning out of Kinshicho, with reception from 9:00. Its two menus look like a nude tier and a clothed tier, but run the arithmetic and every block on the board prices out at exactly ¥200 a minute — so the only real decisions left are where you meet, how you book, and whether you commit to the length before the clock starts.
