Tachikawa is thirty-five minutes from Shinjuku on the Chuo Line rapid and about a decade from Tokyo as anyone outside Japan imagines it. It's a real city — 180,000 people, a monorail, a Lumine, an IKEA, a former US airbase turned into a park big enough to get lost in. What it is not is a pleasure district. There's no neon canyon here, no touts, no Kabukicho theater. There's a station, a department store, a bank of business hotels, and an enormous population of adults living ordinary suburban lives within a ¥2,000 delivery radius.
That last sentence is the entire business model of Midarezuma — 乱妻, which you could render as "unruly wives" if you wanted to be polite about it — a delivery health (deriheru: a licensed dispatch service where a woman comes to your hotel room or residence, and where penetrative sex is prohibited both by law and by the shop's posted rules). The concept line is beautiful amateur wives, secret affairs. The married-woman genre, in other words, which in the Tokyo suburbs is less a fetish category than a demographic description.
I went out there on a Monday afternoon in August specifically because it's the least interesting time and place I could think of. That's usually when a shop tells you the truth about itself.
The ¥2,000 with no name on the front page
Start with the price board, which is clean and easy to read:
| Course | Price |
|---|---|
| 60 min | ¥15,000 |
| 80 min | ¥19,000 |
| 100 min | ¥23,000 |
| 120 min | ¥27,000 |
| 180 min | ¥41,000 |
| 240 min | ¥54,000 |
| Extension, 30 min | ¥8,000 |
Nomination runs ¥1,000 if you're picking from the site listing and ¥2,000 to request a specific woman directly. Cancellation is ¥5,000. A change of partner costs you the transport fee again.
Now open the coupon page, where three offers are posted, and read the struck-through "regular" prices they're discounting from:
| Coupon | Advertised | Struck-through "regular" | Price sheet says |
|---|---|---|---|
| First-timer, 100 min | ¥18,000 | ¥25,000 | ¥23,000 |
| Trial course, 60 min | ¥12,000 | ¥17,000 | ¥15,000 |
| Member points, 80 min | ¥14,000 | ¥19,000 | ¥19,000 |
Two of the three are exactly ¥2,000 above the posted course price. Not a rounding artifact, not a seasonal adjustment — the same ¥2,000, twice. And the first-timer coupon says why, in its own fine print: entry fee waived, normally ¥2,000.
So there's a ¥2,000 membership fee on your first visit that the main price table doesn't include, and the coupon board reveals it by accident because it needs a bigger number to discount from. Add nomination and you're ¥3,000–¥4,000 over the headline before anyone has left the office.
I want to be fair here: an entry fee is completely standard in this trade, it's disclosed on the coupon, and ¥2,000 is on the low end. Nobody is running a scam. But it's a useful demonstration of how to read one of these sites — the price sheet is the advertisement, the coupon page is the accounting, and when they disagree the difference is always a fee.
The genuinely good news is that if you're a first-timer, the entry fee is moot. The house waives it and gives you a tiered discount on top: ¥3,000 off 60 minutes, ¥4,000 off 80, ¥5,000 off 100 or longer. The 100-minute first-timer deal at ¥18,000 is the best-value line on the entire board, and the ¥12,000 trial hour undercuts it only if you genuinely want an hour. There's also a points system — 2% accrues per visit, capped at ¥5,000 off a single use — which is the closest thing here to a loyalty program.
The transport table is a portrait of the customer
This is the part I actually came for, and it's the most informative document on the site.
| Zone | Fee |
|---|---|
| Hotels around Tachikawa Station | Free |
| Tachikawa city, Kunitachi, Hino, Akishima | ¥1,000 |
| Kokubunji, Hachioji, Fuchu, Tama, Kodaira, Higashi-Yamato, Koganei, Higashi-Murayama, Musashi-Murayama | ¥2,000 |
| Mizuho, Akiruno, Mitaka, Chofu, Inagi, Hamura, Ome, Nishi-Tokyo, Kiyose, Higashi-Kurume, Tokorozawa | ¥3,000 |
| Musashino, Komae, Machida, Sagamihara, Kawasaki (part) | ¥4,000 |
| Beyond | ¥5,000+ |
Look at what that map is describing. It is not a nightlife catchment. It's a residential one — twenty-odd municipalities of the western Tokyo commuter belt, out past where the Yamanote-line tourist ever goes, and one of them (Tokorozawa) isn't even in Tokyo. It reaches into Saitama and down into Kanagawa. A shop dispatching to Sagamihara for ¥4,000 is not competing for a night-out crowd; it's serving people who are already home.
Which reframes the whole "married wives" concept, incidentally. In Kabukicho the hitozuma genre is a costume. Out here it's a shop and a customer base drawn from the same twenty suburbs, which is a different proposition entirely, and explains why the discretion language on this site is heavier than the erotic language.
Practical version: budget ¥1,000–¥2,000 for transport if you're anywhere near Tachikawa, and note that station-area hotels are free — which means the cheapest way to do this is to book a business hotel within walking distance of the north exit rather than have her cross three cities to reach you.
51 women, 24 reviews, and a roster that skews to its thirties
The roster page reports 51 women. I went through the ages.
| Age band | Count |
|---|---|
| 20s | ~18 |
| 30s | ~27 |
| 40s and up | ~6 |
Youngest listed, 23. Oldest listed, 58. The center of gravity is squarely mid-thirties, which for this genre is exactly right and refreshingly unfudged — plenty of "married wife" shops post a roster of twenty-four-year-olds and dare you to say something. Heights run T140 to T172, cups from B to I. Nobody has been sorted into a type.
Then the information problem, which is real. Of those 51 profiles, 18 carry a photo-diary (shameru nikki — the self-posted photo journal that's the main way you get a read on someone before booking), exactly one has video, and only five have any customer reviews at all. The rest carry a seeking reviews tag, which is the industry's way of saying the space is empty.
Shop-wide, the review board holds 24 posts. Fifty-one women, twenty-four reviews, and the reviews cluster on a handful of names. Two-thirds of this roster is a blank page.
I'd also treat the totals in those reviews loosely. The recent posts report figures like 100 minutes at ¥19,000 and 120 minutes at ¥30,000 — the first sits well under the sheet, the second well over, and neither reconciles to the price board the way the Kinshicho shops I've written up do. Coupons, transport, entry fees and options all land in the same reported number without being itemized. The shop replies to every review, and every reply is the same warm block of nothing. Don't build a budget on that board. Get the total on the phone.
10:00 to 29:00
The listed hours are 10:00–29:00 — in industry clock notation, ten in the morning until five the next morning, last booking at 28:00. Open every day, no closing days.
Nineteen hours is a long shift for a suburban shop, and the shape of it tells you who calls when. A 10am open is a daytime-customer signal — this is a genre where a meaningful share of bookings happen between the school run and dinner. The 5am close is the other end: the last trains out of Shinjuku dump people into Tachikawa around 1am, and the shop stays open four hours past that.
When I loaded the page mid-Monday-afternoon, five women were showing as available with times attached, several more listed with a next up at 19:00-style slot. Five on a Monday afternoon in a suburb is thin but functional. If you want choice rather than availability, don't come at 3pm on a weekday.
I called. The number is 042-595-7377, a local 042 line rather than an 03 mobile front, which is a small mark of a shop that intends to stay put. The desk was unhurried and slightly formal — none of the hard-sell rhythm you get in the central districts. I asked the three questions that matter at any deriheru and got straight answers on all three: what's the total including transport to where I am, is the entry fee applied, and which of the currently-available women has actually worked recently rather than just being listed. No upsell into a longer course, no attempt to steer me into free-select.
She arrived within the window I was quoted, and I'll leave the room out of it — that's not what this column is for and it isn't really what the shop is selling. What Midarezuma is selling is the thing the suburbs are always selling: proximity, discretion, and a total you can predict. On the first two it delivers well. On the third, only if you ask.
Who this is for, and who it isn't
If you're a visitor staying in central Tokyo, this shop is not for you and I'd say so plainly. The transport tiers alone will eat the discount, the site is Japanese-only with no indication of English-capable staff, and there are three hundred shops within walking distance of wherever you're sleeping. Nothing about Midarezuma rewards a special trip.
If you live in the Tama area — Tachikawa, Hachioji, Kokubunji, Fuchu, out along the Chuo and the Keio lines — the calculus inverts completely. This is a licensed, long-hours, no-days-off shop with a fifty-plus roster whose age range is honestly posted, a transport map that actually reaches your address, and a first-visit offer that's the best-priced thing on it. That's a solid local option, and "solid local option" is a category that gets written about far less than it deserves because it doesn't photograph well.
The rules are posted and they're the standard licensed set: no under-18s, penetrative sex prohibited, no photography or recording, shower first, no arranging to meet outside the shop. The concept page leans hard on discretion, which in a shop whose delivery zone is somebody's actual neighborhood is not marketing copy — it's the product.

The verdict
| Item | Rating |

| Roster honesty — real age spread, no cosmetic sorting | ★★★★★ |
| Coverage — dispatch across 20+ municipalities | ★★★★☆ |
| Desk handling (straight answers, no upsell) | ★★★★☆ |
| Hours and availability (19 hours daily, thin on weekday afternoons) | ★★★☆☆ |
| Price transparency (¥2,000 fee visible only via the coupon page) | ★★☆☆☆ |
| Usable customer information (24 reviews across 51 women) | ★★☆☆☆ |
| Overall | ★★★☆☆ |
Three and a half rounded down, and the half-star I'm withholding is entirely about information. Everything Midarezuma does operationally, it does at a competent suburban standard — long hours, wide delivery, an unairbrushed roster, a desk that answers questions. What it won't do is tell you the whole price on the page where the price is, or give you enough of a review base to pick well.
Both of those are fixable by you, on the phone, in ninety seconds. Ask for the all-in total to your address including entry fee and transport, ask which of the available women has been on shift lately, and take the first-timer coupon on your first call rather than your second.
Do that and this is a good, plain, unglamorous shop in a good, plain, unglamorous city. Which — after enough years of Kabukicho — starts to sound less like a criticism and more like the point.
