The number is the name
Shinjuku Thank You — 新宿サンキュー, filed under 激安 on its listing, which is the category tag for ultra-budget — is a delivery health working Shinjuku, Kabukicho and out toward Shin-Okubo, dispatching across the metro area. Twenty-four hours. Phone is 03-6806-7639, the official site is 39group.info/shinjuku/, and the parent Sankyu Group lists forty-plus shops nationwide.
Base course: 30 minutes, ¥3,900.
I've written about the ¥3,900 before and I was looking at the wrong number. The base rate is not where the decision lives. It's ¥130 a minute, it's genuinely low, and it's also almost beside the point, because it is not what most people actually buy. What they buy is the thing on the other side of the nomination fee.
Two shops wearing one sign
Read the option page carefully and the shop quietly splits in half.
Book the free course — no nomination, take whoever is available — and what you get is kihon play: nine standard items, listed plainly, kissing through to the usual. That's the whole menu. It is not a stripped version of the full experience; it's a different, smaller product.
Add the nomination fee of ¥2,000 and the shop opens up roughly a hundred free options. Not discounted. Free. The shop's own language is direct about the pitch — traditional shops bill each option individually, so bundling them is the differentiator — and the free-option list runs deep into territory most budget houses charge separately for, with the standing caveat that what's actually on offer varies girl to girl and you check her profile, not the shop's.
So the ¥2,000 is misnamed. It isn't a nomination fee in the usual sense of paying for choice. It is the menu. Nine acts on one side of it, about a hundred on the other, and the only thing you're really deciding when you call is which of the two shops you want to be in.
Worth flagging one inconsistency: the listing advertises "50-plus" free options while the shop's own option page says roughly a hundred. Both are the shop talking about itself and they disagree by a factor of two. Neither number is the point — her profile is — but if somebody quotes you a count at reception, that's where the gap comes from.
The menu tax is a percentage, and it moves
Now the part that actually changed how I booked.
Because the unlock is a flat ¥2,000 regardless of course length, its weight depends entirely on what you attach it to. Run it:
- 30 minutes, ¥3,900 → the fee is a 51% surcharge
- 75 minutes, ¥8,000 → 25%
- 300 minutes, ¥29,000 → 6.9%
That is a strange and slightly perverse gradient. The cheapest course on the board is the one where the shop's signature feature — the hundred-option menu — is proportionally most expensive to reach. The ¥3,900 door is the single worst place in the shop to buy the thing the shop is known for.
Which flips the usual budget-shop advice. Normally the move at a gekiyasu house is to take the minimum and get out cheap. Here, taking the minimum means either paying half again on top for the menu, or accepting the nine-item version and never seeing what you came for. The value doesn't live at the bottom of the ladder. It lives about halfway up, where ¥2,000 has stopped mattering and the per-minute rate hasn't started climbing.
There is a pothole in the ladder
The promotional courses on the listing are worth reading with a calculator, because one of them is dominated on both sides.
75 minutes, ¥8,000 — ¥107 a minute, and there's a free-course version at the same ¥8,000. 80 minutes, ¥10,000 — ¥125 a minute. 70 minutes, ¥9,800 — ¥140 a minute.
Look at those first and third lines again. Seventy-five minutes costs ¥1,800 less than seventy minutes. Five minutes more, eighteen hundred yen cheaper. And the 80 beats the 70 on rate as well, so the seventy-minute course is worse than the option above it and worse than the option below it simultaneously.
I don't think that's a trap; promotional slates in this industry accrete over time and lines stop getting compared to each other. But it is sitting right there on the board, and if you phone in and ask for "about seventy minutes" you can pay a premium for the privilege of a shorter booking. Ask for the 75.
For a first visit the shop runs 50 minutes at ¥8,000 with the nomination fee included — ¥160 a minute all-in, which reads expensive per minute until you remember it's the full-menu product with no second number attached. As an introduction to what the ¥2,000 actually buys, it's the honest way in.
There's also a group discount, ¥1,000 off for three or more people on courses of 60 minutes and up, which is not a line I expected on a deriheru fee sheet and I'll leave to your own arrangements.
One in the morning to six
The course I'd actually defend is the one you can only buy when the trains have stopped.
300 minutes for ¥29,000, running 1:00 to 6:00. That's ¥97 a minute — the cheapest minute in the shop by a clear margin, twenty-five percent under the ¥130 headline that the whole brand is named after. Add the ¥2,000 and you're at ¥31,000, ¥103 a minute, still cheaper than the base course before its unlock.
The listing shows this course at ¥29,800 rather than the ¥29,000 on the shop's own site. Eight hundred yen, and I'd assume the listing figure is the one you'll be quoted. Know the gap before you argue about it; it isn't a bait, it's two pages updated on different days.
The mid-band the shop describes in ranges rather than exact figures — 90 minutes in the ten-thousands, 150 minutes in the twenty-thousands — sits about where you'd expect between those poles.
What the overnight block really tells you is where this operation's weight sits. A shop that prices its deepest discount into the 1 a.m.–6 a.m. window is a shop whose supply is most available exactly when the rest of the city has gone home, and it's pricing to fill hours it would otherwise idle. Twenty-four-hour operation isn't a slogan when the fee sheet is built around the back half of the clock. In Kabukicho, at that hour, the phone answering at all is the product.
The number that isn't on the sheet
One gap I'd close before you book: no transport or dispatch fee is stated on either the listing or the shop's own pages. Neither says it's free, either. For a delivery operation running the whole metro area from Shinjuku, the distance between your hotel and theirs is the one variable that can move a total, and it's the one figure I couldn't find printed anywhere. Ask when you call. Everything else on this fee sheet is unusually legible; that one just isn't on it.

The thing I got wrong about Shinjuku Thank You the first time was treating ¥3,900 as the offer. It's the name. The offer is a flat ¥2,000 that swaps a nine-item menu for something close to a hundred, and every real decision here is about how much course you attach that ¥2,000 to so it stops mattering.
Book short and you'll pay a fifty-percent premium for the shop's whole personality, or skip it and buy a product this place doesn't really sell. Book the 75 instead of the 70. Book the 300 if you're still awake at one. Ask what the car costs.
Do that and the arithmetic is as good as it looks on the sign — which, given that the sign is also the name, the group, and the domain, is a claim the shop has made genuinely difficult to walk back.
