Koiwa at Noon: Doing the Math on Mugen Hassha!! Okusama Deli Kyubin's First-Timer Rates

A 24-hour married-women delivery health on Tokyo's far east edge with a ¥13,000 board and an ¥8,000 first-timer price. I read the whole menu, the coupon page and a week of shifts from a Koiwa coffee shop, and worked out which booking actually saves you money and which 'deal' quietly costs extra.

Koiwa at Noon: Doing the Math on Mugen Hassha!! Okusama Deli Kyubin's First-Timer Rates
Elon
ElonKoiwa isn't a place people go on purpose. It's the last stop in Tokyo before the Edogawa River and Chiba. I like neighborhoods like that, because the shops there can't coast on foot traffic, so they compete on price. This one competes hard on the first visit, and then the numbers start getting creative. Below is the version I wish someone had handed me: what the first-timer price really buys, where the extension math bites, and the one hour of the day when the nomination fee goes to zero.

Last stop before the river

Friday, a little before one in the afternoon. I came out of the south exit of JR Koiwa and found what Koiwa always has: a long covered shopping street, old guys on bicycles, a pachinko parlor playing to nobody, and a chain coffee shop with an outlet by the window. That's where I set up, with the shop's Cityheaven page open on my phone.

The shop is Mugen Hassha!! Okusama Deli Kyubin, Koiwa branch. The name translates roughly as "Unlimited Release!! Housewife Express." Subtle, it is not. It's a delivery health (deriheru): no storefront, she comes to your hotel. The listing says the dispatch area is Koiwa, Edogawa-ku, and it is open 24 hours, no days off. The phone is 03-6807-4557, and like everywhere on that portal, saying "Heaven mita" ("I saw you on Heaven") when you call is how you get the listed deals.

The pitch on the top page is laid on thick. It's a long paragraph about "the grown woman's real strength", experienced women, "renting someone's wife." Then comes one line I actually appreciated: no flashy cosplay, no extreme play. The advertised product is hitozuma and jukujo, married women and mature women, and nothing else. At the top of the page sits a short Koiwa blurb: calm, adult women, for guys who want to take it slow.

The board, and what it isn't telling you

Here's the standard price list, in yen:

Course Price Per minute
60 min ¥13,000 ¥217
90 min ¥18,000 ¥200
120 min ¥24,000 ¥200
150 min ¥30,000 ¥200
180 min ¥35,000 ¥194

Add-ons: transport is ¥1,000 anywhere in the 23 wards (outside that, ask). Nomination is ¥1,000, a repeat nomination (hon-shimei) ¥2,000. Extensions cost ¥7,000 for 30 minutes and ¥15,000 for 60. A change (sending her back for someone else) is ¥5,000. A cancellation costs 50% of the total.

The first thing I noticed is that the extensions are priced above the courses. A 30-minute extension runs ¥233 a minute and a 60-minute one ¥250, against ¥200 a minute for the course itself. So:

  • 60 min + 30-min extension = ¥20,000. Booking 90 from the start = ¥18,000.
  • 60 min + 60-min extension = ¥28,000. Booking 120 from the start = ¥24,000.
  • And the 60-minute extension (¥15,000) costs more than two 30-minute ones (¥14,000).

If there's any chance you'll want more time, book it up front. Extending is the most expensive way to buy minutes on this whole menu.

Then the 50% cancellation fee. On a 120-minute booking that's ¥12,000 for changing your mind. Some delivery shops charge a flat fee or nothing. This one charges half, so don't book from the train before you know your evening.

The first-timer price is the real product

The coupon page and the event page tell the same story, and it's a good one:

First-timer offer Regular First-timer Off
60 min ¥13,000 ¥8,000 ¥5,000
90 min ¥18,000 ¥12,000 ¥6,000
120 min (web booking only) ¥24,000 ¥18,000 ¥6,000

That's ¥133 a minute at 60 or 90, against ¥200 off the board. For a first visit, the 90-minute course at ¥12,000 is the sweet spot. It costs the same per minute as the 60, and you never have to look at that ugly extension table. Add ¥1,000 transport and the delivery side comes to ¥13,000, the same as the board price for 60 minutes. The hotel room is on you, and the shop doesn't publish a partner list, so budget for that separately.

The 120-minute first-timer offer is the one with a string: net booking only. It also saves the same ¥6,000 as the 90, so per minute it's worse (¥150). Unless you know you want two hours, the 90 is the better deal.

How to claim it: tell them on the phone you saw the first-timer price on Heaven. The 60-minute coupon says "tell them you saw the coupon," the 90-minute one says "tell them 'Heaven mita'," and the event page says to mention the shinki-wari (new-customer discount). Three phrasings, one deal. Say all three if you're nervous.

Sugu-wari: the free nomination window

This is the part most people will scroll past, and it's the smartest thing on the page. It's called Sugu-wari, roughly "right-now discount," and it's been running since March:

  • Nomination fee waived (normally ¥1,000)
  • Weekdays, until 18:00 only
  • Only when three or more women are on standby (soku-hime, "available right now")
  • Works with any course, but not for repeat nominations
  • Say "Sugu-wari" when you book

What the shop is really saying: we've got women sitting around in the afternoon, so come pick one. It's a capacity-clearing deal, and when you show up decides whether you get it.

I don't know whether Sugu-wari stacks with the first-timer price. Neither page says so either way. I'd ask, and I'd assume it doesn't until a human on the phone says it does. Even alone it's ¥1,000 back for picking your own woman on a weekday afternoon. That's the whole nomination fee.

Reading the shift board

The weekly schedule is where this shop gets interesting, and a little strange. There are 17 women on the roster, and all 17 are on today. They're also all on every day of the coming week, with exactly the same hours every day. Matsui finishes at 5:30 instead of 6:00 one night. That's the only variation across 102 listed shifts.

Real people don't work seven days a week on identical shifts. My read is that the board shows standing hours, each woman's usual window, not a confirmed schedule. The page says so in its own small print: schedules are plans, call for the latest. So take it as a map of who works when, not as a promise.

The map is useful, though. Here's roughly how many women the board puts on duty at different times:

Time Women on the board Sugu-wari possible?
07:00 3 barely, all three must be free
09:00 4 yes, if three are idle
13:00 6 yes, the sweet spot
17:00 11 yes, until 18:00
19:00 13 no, after 18:00
22:00 12 no
03:30 9 no
05:30 6 no

The day crew is Kikuchi (37), Yonekura (34), Furukawa (33), all 6:00–18:00. Watanabe (38) works 8:00–21:00, Mita (35) 10:00–22:00, and Yoshida (36) 13:00–23:00. Then the evening wave arrives from 15:00: Uchida, Kondo, Ichinose, Fujisaki, Tomita. The 18:00 group of Himekawa, Matsui, Katsura, Kato and Sasazaki stays until six in the morning, and Ozono (39) closes the night from 20:00. Ages run 27 to 39, averaging about 34. That's a little younger than "jukujo" suggests. It's a married-women shop more than a mature-women shop.

When I checked at 12:49, the "available right now" panel showed six women on standby. That's the day crew plus Watanabe, Mita and Yoshida, so Sugu-wari was live. Two of those six, Kikuchi and Mita, are also the faces on the first-timer coupons.

Two caveats. Monday the 12th is Sports Day, a national holiday. The event says "weekdays," and I wouldn't count on a holiday Monday qualifying. And no one on the roster has a review yet. Every profile says "reviews wanted." You're picking off photos, measurements and the women's own photo diaries, and the diaries are mostly Watanabe. The empty review column has an obvious explanation: the banner on the top page still says "New Grand Open!" The Koiwa branch is new, and its first-timer pricing reads like a shop buying its first regulars.

The options menu, read with a straight face

The shop's name is "unlimited release," and that's on the menu as a literal line item: unlimited finishes within your time, free. Also free: a rotor and cosplay. That's slightly funny given the "no flashy cosplay" line on the top page, but fine.

Paid options climb from ¥1,000 through ¥3,000, ¥5,000 and ¥8,000 tiers. Photo options start in the cheap tiers; the expensive ones are mostly filming, face hidden or shown. One sentence matters more than the prices: options are confirmed with the woman. In plain English, the menu is a list of what you may ask about, not a list of what you're owed. Ask politely and take no for an answer.

How I'd book it

If I were doing this on a weekday, this is the call I'd make, and why:

  1. Call between 12:00 and 17:00 on a weekday (not the 12th). Six to eleven women are on the board then, and Sugu-wari is in play.
  2. Ask for the first-timer 90 minutes at ¥12,000. Mention Heaven.
  3. Ask whether Sugu-wari also applies, so you can pick a woman without the ¥1,000 fee. If it doesn't stack, decide whether picking is worth ¥1,000. At ¥12,000 for 90 minutes, it probably is.
  4. Say yes to the time you actually want up front. Never extend here.
  5. Have the hotel sorted before you call. A 50% cancellation fee isn't something to gamble on.

All in, delivery side: ¥13,000 to ¥14,000 for 90 minutes with a woman you chose. On a second visit the same 90 minutes runs ¥18,000 + ¥2,000 repeat nomination + ¥1,000 transport = ¥21,000. That's the real price of this shop, and it's why the first visit feels like a bargain. It is one. It's also an audition, and you're the one being auditioned.

Verdict

Board price ★★★☆☆, ordinary for Tokyo hitozuma delivery
First-timer price ★★★★★, ¥133/min for 90 minutes is hard to beat
Extensions ★☆☆☆☆, priced above the courses; book long instead
Cancellation ★★☆☆☆, 50% of the total
Sugu-wari ★★★★☆, free nomination on weekday afternoons
Schedule honesty ★★☆☆☆, identical hours all week, so treat it as a template
Concept clarity ★★★★☆, married women, ages 27–39, no gimmicks

Koiwa doesn't have glamour and doesn't pretend to. This shop's opening offer, 90 minutes for ¥12,000 on a weekday afternoon with the nomination fee possibly waived, is about as good a first date with the far east side of Tokyo as I've seen this year. Just know which numbers are the bargain and which are the bill. I finished my coffee, put the phone face down, and walked back toward the station with the 90-minute plan in my head. The river was right there. I could smell it.
