Themis — テミス, filed on Cityheaven as 銀座/デリヘル and tagged 高級 — is named for the Greek goddess of θέμις: divine law, custom, the order of things. The tagline leans all the way in. 掟に護られた大人の秘密倶楽部 — an adults' secret club protected by unwritten law. The site lists three rules for the men who come here: be a gentleman, respect beauty, value time.
I want to take that last one literally, because this shop sells time in blocks and prices those blocks in a code, and the code is worth reading before you call.
Delivery health — no storefront, she comes to your hotel or your apartment. Hours are 10:00 to 24:00, a fourteen-hour day, closed only on New Year's Eve and New Year's Day. Outside hours are negotiable in advance. Phone is 03-6821-5756, and the shop's own site is at ginza-themis.jp.
That last detail matters more than it usually does, and I'll get to why.
The courses are Greek numerals
Here is the complete price list. Not the Cityheaven version — the shop's own /system page, which carries one row the aggregator doesn't:
| Course | Duration | Price | Extension 30 min |
|---|---|---|---|
| TETRA (official site only, free-select only, first visit only) | 70 min | ¥40,000 | — |
| PENTA | 90 min | ¥50,000 | ¥25,000 |
| PENTA | 120 min | ¥70,000 | ¥25,000 |
| OCTA | 90 min | ¥80,000 | ¥40,000 |
| OCTA | 120 min | ¥110,000 | ¥40,000 |
| KALON PREMIUM | — | ASK | — |
Read the names.
Tetra is four. The course costs ¥40,000. Penta is five. ¥50,000. Octa is eight. ¥80,000. The Greek numeral in each course name is the entry price in units of ten thousand yen, exactly, three times in a row. This isn't a coincidence I'm reaching for — it's a naming scheme, and it holds across every course the shop has put a number on.
Now the fourth. KALON is not a numeral. It's τὸ καλόν — the noble, the fine, the beautiful, the word Greek ethics reaches for when it means good in a way that isn't measurable. And its price is ASK.
A shop named after the goddess of law prices its menu by a rule, and then puts its most expensive tier exactly where the rule runs out. I've read a lot of price pages in this industry. That's the most coherent one I've come across, and I don't think it's an accident.
The ¥40,000 door is invisible from the aggregator
TETRA appears on the shop's own system page. It appears zero times on Cityheaven's shop top page, zero times on Cityheaven's system page, and zero times on Cityheaven's coupon page. I checked all three.
So the cheapest way into this shop — ¥40,000, seventy minutes — cannot be found by anyone browsing the aggregator. And the aggregator is where the coupons live. The shop has split its two cheapest offers across two different websites.
Before you conclude TETRA is the move, do the division. It isn't, quite:
| Option | Course price | Per minute |
|---|---|---|
| TETRA 70 min | ¥40,000 | ¥571 |
| PENTA 90 min | ¥50,000 | ¥556 |
| PENTA 120 min | ¥70,000 | ¥583 |
| OCTA 90 min | ¥80,000 | ¥889 |
| OCTA 120 min | ¥110,000 | ¥917 |
| PENTA extension, 30 min | ¥25,000 | ¥833 |
| OCTA extension, 30 min | ¥40,000 | ¥1,333 |
The special first-timer plan is not the best rate the shop sells. TETRA runs ¥571 a minute; the standard PENTA ninety runs ¥556. TETRA lowers the ticket, not the rate. It's ¥10,000 less money for 20 fewer minutes — which prices those twenty minutes at ¥500 each, and there is no cheaper twenty minutes on this menu.
Add the ¥5,000 transport fee and the gap widens, because a flat fee spread over a shorter booking hurts more:
| Option | All-in (23 wards) | Per minute |
|---|---|---|
| TETRA 70 min | ¥45,000 | ¥643 |
| PENTA 90 min | ¥55,000 | ¥611 |
| PENTA 120 min | ¥75,000 | ¥625 |
| OCTA 90 min | ¥85,000 | ¥944 |
| OCTA 120 min | ¥115,000 | ¥958 |
Once transport is counted, TETRA is the worst per-minute value of every PENTA-grade option on the board. It wins exactly one thing, and it's not nothing: ¥45,000 is the smallest number this shop will take, and it's the only way to spend under ¥50,000 here.
Both tiers run the same formula
Fit a line to each ladder and the structure falls out clean.
PENTA goes ¥50,000 → ¥70,000 across 90 → 120 minutes: ¥20,000 for 30 minutes, a marginal rate of ¥666.7 a minute. Solve for the constant and you get PENTA = ¥666.7/min − ¥10,000. Check it: 666.7 × 90 − 10,000 = ¥50,000. 666.7 × 120 − 10,000 = ¥70,000.
OCTA goes ¥80,000 → ¥110,000: ¥30,000 for 30 minutes, ¥1,000 a minute. OCTA = ¥1,000/min − ¥10,000. Check it: 1,000 × 90 − 10,000 = ¥80,000. 1,000 × 120 − 10,000 = ¥110,000.
Same shape. Same constant. The only thing that changes between the ¥50,000 tier and the ¥80,000 tier is the meter, and the meter goes up by exactly one half — ¥666.7 to ¥1,000 is precisely 1.5×. The −¥10,000 you get for booking a longer block is identical in yen whether you're buying the cheap tier or the expensive one.
That negative constant is why per-minute cost rises with duration here rather than falling. You're getting a flat ¥10,000 off a metered rate, so the longer you stay, the less that fixed discount is worth per minute. Both tiers drift toward their meter and never reach it. It's a mild effect — ¥556 to ¥583 on PENTA — but it points the opposite way from the usual "buy long, save money" instinct, and it means on rate alone, the ninety is the better buy in both tiers.
Extensions cost more than the same minutes bought upfront
This is where the menu has teeth.
Thirty minutes bought inside a PENTA course costs ¥20,000 — that's the 90-to-120 step. The same thirty minutes bolted on after costs ¥25,000. A 25% penalty for deciding late.
On OCTA, inside is ¥30,000, extension is ¥40,000. A 33% penalty.
In absolute terms: booking PENTA 120 upfront saves ¥5,000 over PENTA 90 plus an extension. Booking OCTA 120 upfront saves ¥10,000.
Hold onto those two figures — ¥5,000 and ¥10,000 — because they turn up again immediately.
The coupons, and what they actually discount
Two coupons on Cityheaven, both new-customers-only, both dated 2026/02/07 with no expiry, both marked no-stacking. Say ヘブンを見た when you call. Here's what each one really does, from the coupon's own itemized table:
PENTA coupon, badged 9% OFF:
| Normal | With coupon | |
|---|---|---|
| Transport | ¥5,000 | ¥5,000 |
| PENTA 90 min | ¥50,000 | ¥45,000 |
| Total | ¥55,000 | ¥50,000 |
OCTA coupon, badged 12% OFF:
| Normal | With coupon | |
|---|---|---|
| Transport | ¥5,000 | ¥5,000 |
| OCTA 90 min | ¥80,000 | ¥70,000 |
| Total | ¥85,000 | ¥75,000 |
Three things in there.
One: the discounts are ¥5,000 and ¥10,000 — the exact same two numbers as the extension penalties above. The new-customer coupon hands back precisely what booking indecisively costs you. Whether that's design or arithmetic coincidence I can't say, but it's true to the yen in both tiers.
Two: the PENTA coupon is exactly the transport fee. ¥5,000 off, ¥5,000 to get her there. Your all-in lands at ¥50,000 — the list price of the course itself. She travels free, precisely.
Three: the percentage badges are computed on the transport-inclusive total, which understates them. ¥5,000 off ¥55,000 is 9.09%, so the badge says 9%. But against the course price you're actually discounting — ¥5,000 off ¥50,000 — it's a clean 10%. Same on OCTA: ¥10,000 off ¥85,000 reads as 12%, while ¥10,000 off ¥80,000 is 12.5%.
The shop picked the larger denominator and made its own discount look smaller. In a business where I routinely find percentages inflated by measuring against prices nobody pays, a shop rounding its own deal down is worth saying out loud.
The ¥75,000 fork
Put the coupons on the table and a first-time visitor with ¥75,000 finds two doors at exactly the same price:
- OCTA, 90 minutes, couponed — ¥70,000 + ¥5,000 transport = ¥75,000
- PENTA, 120 minutes, list price — ¥70,000 + ¥5,000 transport = ¥75,000
Identical money. One tier up, or thirty more minutes. That's the actual decision this menu is built to ask, and it only appears if you lay the coupon page over the price page.
Worth noting: as published, both coupons specify the 90-minute course. Neither one is written against the 120. And the couponed OCTA 90 works out to ¥833 a minute all-in — cheaper per minute than an uncouponed OCTA will ever be again, since list OCTA 90 all-in is ¥944.
If you intend to try OCTA at all, the first visit is structurally the cheapest it gets. The step up from PENTA to OCTA costs ¥30,000 at list and ¥25,000 with both coupons applied to their respective courses.
The roster: sixteen women, and the tier isn't about age
Sixteen women listed. Ages 26 to 38, averaging 31.0, median 30.5. Heights 152 to 170, averaging about 162 — noticeably tall for the field. Cup sizes run C through G.
The shop says it selects women 25歳以上を中心に — centered on 25 and over. The youngest woman on the roster is 26. Not "mainly" — all sixteen clear the stated bar. I check claims like this expecting to find the exception. There isn't one.
Now the part that took cross-referencing. The shop's own cast page tags every woman with her course tier, and that mapping doesn't exist on Cityheaven at all. Here's the whole roster:
| Tier | Count | Ages | Listed day jobs |
|---|---|---|---|
| PENTA ¥50,000 | 5 | 28, 28, 29, 30, 30 | foreign-firm employee, department-store beauty adviser, Marunouchi office worker, reader model, shop assistant |
| OCTA ¥80,000 | 8 | 26, 26, 29, 32, 33, 35, 35, 38 | high-class lounge, cabin attendant, freelance announcer, club hostess, part-time lecturer, married ex-CA, etiquette instructor, gravure model |
| KALON ASK | 3 | 31, 32, 34 | actress, TV talent, undisclosed |
Two findings, and the second is the real one.
The ¥50,000 headline buys you five of the sixteen. Half the roster sits at ¥80,000. Another fifth has no published price whatsoever. The median woman at this shop is an OCTA woman, and the number on the front of the menu covers under a third of the building.
And the ladder is not sorted by age. Look at it again. Both 26-year-olds — the two youngest women here — are in the ¥80,000 tier. So is the 38-year-old, the oldest. Meanwhile the cheapest tier has the tightest and nearly the youngest band on the roster: 28 to 30, average 29. KALON, the tier with no price at all, is 31, 32, 34 — squarely mid-roster.
Whatever you're paying the extra ¥30,000 for, it is demonstrably not youth.
Read the right-hand column and the actual variable shows itself. PENTA is ordinary daytime work — shop floors, offices, a department store counter. OCTA is client-facing and camera-facing — cabin crew, broadcast, hostessing, gravure, instruction. KALON is 女優, タレント, and 非公開: an actress, a TV personality, and a woman whose occupation the shop declines to state at all.
The price ladder at Themis is a discretion ladder. It's sorted by how public the woman's daytime face is — by how much she has to lose. That's what the tiers are actually measuring, and once you see it, the shop's whole posture snaps into focus: the goddess of unwritten law, the club protected by 掟, the explicit refusal to keep a group waiting room. The concept copy and the price list are describing the same product from two directions.
Which also explains KALON. You can't put a number on that tier because the thing being priced is the thing the shop won't specify.
Fees the aggregator doesn't carry
The official system page lists several charges Cityheaven either omits or leaves vague:
- Photo nomination: free. Membership fee: free. Choosing her from the photos costs nothing.
- 本指名 (asking for her again): ¥5,000 and up. Picking her the first time is free; requesting her by name the second time is not.
- Transport: ¥5,000 in the 23 wards; ¥7,000 and up outside the wards and neighboring prefectures. Cityheaven only says outside-the-wards "varies by distance." The shop's own page puts a floor on it.
- Payment: various methods accepted, and receipts are issued — 領収証発行可能, stated plainly.
That repeat-nomination fee deserves a beat. This is a shop whose entire pitch is continuity — 時を大切にすること, a membership orientation, a four-digit member number you choose yourself and keep. And the relationship it's selling carries a ¥5,000 surcharge the moment you ask for the same woman twice. Free to pick a stranger, ¥5,000 to pick her again. I'd want that number pinned down before assuming it's a flat five.
What the shop won't tell you, and what to ask
I'd rather flag the holes than paper over them.
KALON has no price anywhere. Not on Cityheaven, not on the shop's own site. Three of sixteen women are behind it. ASK is the entire published figure.
Both open-ended fees are open-ended. 本指名 ¥5,000〜 and out-of-ward transport ¥7,000〜 have floors and no ceilings published.
TETRA's terms don't resolve. It's 公式サイト限定 (official site only), フリー限定 (free-select only), 初回限定 (first visit only). Free-select means you don't choose — the house does. But the house runs a three-tier roster where half the women are ¥80,000 and three have no price. Nothing published says which tier a ¥40,000 free-select booking draws from. That's the single most valuable question on this page, and I can't answer it from the sources.
And the two cheapest offers may not combine. TETRA lives on the official site; the coupons live on Cityheaven and say 他クーポン併用不可. Whether a site-exclusive course stacks with an aggregator coupon is unstated. Assume it doesn't and ask.
No service or option list is published on either site. Nothing itemized about what a course contains.
Practical notes
Booking takes a name — a pseudonym is explicitly fine if you're paying cash — plus a reachable phone number. You then pick any four-digit number of your choosing, and that becomes your member number for future visits. Withheld-number calls are accepted, with one condition stated up front: she doesn't depart until your room entry is confirmed.
The shop keeps no group waiting room, stated as a privacy and safety measure for the women. It reads as concept copy but it has a practical consequence — nobody is idling in a standby room ten minutes from your hotel. She's coming from wherever she actually is. Book ahead, especially for a specific woman, especially for the tiers where there are only three or five of them.
Dispatch centers on the 23 wards. The shop says it has sent women beyond Kanto and invites distance inquiries. It also states it takes consultation-only calls and doesn't push bookings — 無理なご予約の強要は一切ございません — which, given the numbers involved here, is a reasonable thing to test before committing ¥75,000.
The verdict
Themis is the rare shop where the pricing is more honest than the marketing, and the marketing is already fairly restrained. The Greek numerals are a genuine code that resolves. The coupon percentages are understated rather than inflated. The stated age policy holds across all sixteen women. The extension penalties are steep but they're published, and the arithmetic is consistent to the yen everywhere I checked it.
What it will not tell you is what KALON costs, or which women a ¥40,000 first-timer actually gets. Those two omissions aren't sloppiness — they're the same omission twice, and it's the one the whole business model rests on.
If you want the cheapest genuine rate: PENTA 90 with the Cityheaven coupon, ¥50,000 all-in, ¥556 a minute — the best per-minute number on the board, and the coupon exactly eats the transport fee. If you want the lowest total spend and don't mind not choosing: TETRA, ¥45,000 all-in, from the official site, and ask which tier it draws from before you hang up. If you're ever going to try OCTA: do it on the first visit, when it's ¥10,000 off and cheaper per minute than it will be again.
And if you're weighing the ¥75,000 fork — thirty more minutes of PENTA, or ninety minutes one tier up — understand what you're really choosing between. Not youth. Not measurements. The shop has sorted its roster by how much of her daytime life a woman is willing to have known, and priced it accordingly.
Prices, hours and roster details above were taken from the shop's Cityheaven listing and its official site at ginza-themis.jp on 2026-07-29 and are quoted as published. Terms change — confirm by phone before booking. Adults 18+ only; the shop states it does not employ anyone under 18.
