Marutsuma Ikebukuro — 丸妻池袋店, read Marutsuma, written on the group's own domain as marujiru — is a married-women delivery house working the north and west sides of Ikebukuro station. It opened August 8th, 2025, making it thirteen months old as I write this, and it is not an independent: it's a node of More Group, the Kanto-wide hitozuma chain whose siblings listed on this very page include Ikebukuro Hitozumajo, Kawasaki-Toyoko Hitozumajo, Odawara Hitozumajo and two Atsugi houses. There is no building. The address field reads "Tokyo, Ikebukuro (Toshima-ku)", which is a neighborhood, not an address, and the room is your problem.
What it has instead of a storefront is 132 registered women, 626 reviews, and a discount architecture with four separate levers that are explicitly forbidden from touching each other.
The Board, Which Is Refreshingly Short
Six courses, one price each, no day rate and no night tax:
- 60 minutes — ¥11,000
- 80 minutes — ¥14,000
- 100 minutes — ¥16,000 (marked recommended)
- 120 minutes — ¥19,000
- 150 minutes — ¥23,000
- 180 minutes — ¥28,000
Longer than 180 is available by stacking courses — the sheet literally offers 100+100 = 200 minutes and 150+150 = 300 minutes as worked examples, and says to call for anything beyond that. Membership is free. Nomination splits the usual Japanese way: ¥1,000 for a woman you've never met (shashin shimei, picking off a photo), ¥2,000 for a woman you're booking for the second time or later (hon-shimei). Extension is ¥7,000 per 30 minutes, flat across every course.
Sit with that extension figure for a second. The 150-minute course runs ¥153 a minute. The extension runs ¥233 a minute — a 52% premium on exactly the same activity, purchased late. This is the single most expensive way to buy time at this shop, and it's the one you reach for in the moment, when you are happy and not doing arithmetic. Book long up front.
Minutes 81 Through 100 Cost ¥100 Each
Run the ladder step by step and the cheapest twenty minutes on the board fall out immediately:
| Step | Extra cost | Extra time | Per minute |
|---|---|---|---|
| 60 → 80 | ¥3,000 | 20 min | ¥150 |
| 80 → 100 | ¥2,000 | 20 min | ¥100 |
| 100 → 120 | ¥3,000 | 20 min | ¥150 |
| 120 → 150 | ¥4,000 | 30 min | ¥133 |
| 150 → 180 | ¥5,000 | 30 min | ¥167 |
Minutes 81 through 100 cost ¥100 each, the cheapest block on the sheet by a third, and it is not a coincidence that 100 minutes is the course the shop tags as its recommendation. The house has priced its preferred product into being obviously correct.
The other end of the ladder is less flattering. The 180 is worse value per minute than the 150 — ¥156/min against ¥153/min — so the longest course on the board is a small step backwards, and it stays backwards even after the anniversary discount (¥127.8/min versus ¥126.7/min). If your budget tops out around ¥23,000, the 150 isn't a compromise. It's the best rate the shop sells.
Four Discounts, None of Which Stack
Here is the full architecture, as published on the events page:
1. The first-anniversary event (running since July 31st). Scales with course length: ¥1,000 off 60 min, ¥2,000 off 80 and 100, ¥3,000 off 120, ¥4,000 off 150, ¥5,000 off 180. Repeat-nomination customers welcome. Explicitly cannot be combined with other events. Excluded from hime-yoyaku, the girl-initiated reservation slots. Net bookings have to write it into the requests field.
2. The new-customer discount (since July 15th). ¥3,000 off any course of 80 minutes or longer, ¥2,000 off the 60. Usable up to three times per person — not just the first visit, the first three. Repeat nomination is excluded, so it only works on a woman you haven't met.
3. The advance-booking discount (since July 15th). Book before the day of use: ¥1,000 off 60, ¥2,000 off 80 and 100, ¥3,000 off 120 and up. Repeat nomination allowed. No combining.
4. Maru no Hi, the fourth Thursday of every month (since August 7th). ¥3,000 off every course, flat. Repeat nomination allowed. The shop adds that stacked with its wake-ari points you can reach "¥6,000 of value," which is the one place in the entire file where something is described as combining with something else. The next one falls on Thursday, September 24th. Write it down.
There is also a micro-bikini meetup, running since August 23rd: she arrives in ordinary street clothes with a micro bikini underneath, and the shop states plainly that it charges no extra fee for it. Say the phrase when you book. In a business where every third gimmick carries a ¥2,000 tag, a free one is worth naming.
Now convert. Same levers, expressed as a share of what you'd otherwise pay:
- 60 min, Maru no Hi: ¥3,000 off ¥11,000 = 27.3%
- 80 min, new-customer or Maru no Hi: ¥3,000 off ¥14,000 = 21.4%
- 100 min, new-customer or Maru no Hi: ¥3,000 off ¥16,000 = 18.8%
- 180 min, anniversary: ¥5,000 off ¥28,000 = 17.9%
- 150 min, anniversary: ¥4,000 off ¥23,000 = 17.4%
- 120 min, any of three levers: ¥3,000 off ¥19,000 = 15.8%
The order is almost exactly inverted from the way the shop advertises it. The ¥5,000 in the starburst sits fourth. The 120-minute course — the one that three separate discounts all happen to land ¥3,000 on — is the worst-discounted slot on the board. And the single best proportional deal in the entire building is the cheapest course on the least glamorous day of the month.
Nine Receipts, Checked Against the Board
Anyone can publish a price list. So I took every review on the front page of the shop's review section that itemized a total — nine of them, all tagged room not included — and reconciled each against the sheet.
- 100 min, ¥15,000, course plus photo nomination. ¥16,000 + ¥1,000 − ¥2,000 anniversary = exact.
- 100 min, ¥15,000, same structure, different visit. Exact.
- 100 min, ¥16,000, course plus nomination plus one of a cast member's own personal options. ¥16,000 + ¥1,000 − ¥2,000 + ¥1,000 = exact.
- 120 min, ¥17,000, described by the reviewer simply as "the 120 rate minus the event discount." ¥19,000 + ¥1,000 − ¥3,000 = exact.
- 120 min, ¥20,000 (September 14th), course plus nomination plus the wand option. ¥19,000 + ¥2,000 + ¥2,000 − ¥3,000 = exact, reading his nomination as the repeat rate — which his own text, three-plus visits and a pre-booking chat with her, supports.
- 100 min, ¥17,000, course plus repeat nomination. ¥1,000 above what one lever predicts; equals the board precisely if no discount was applied at all.
- 180 min, ¥21,000 (September 12th), course plus repeat nomination, anniversary event, 5,000 points spent. My arithmetic says ¥20,000. ¥1,000 adrift, and the only receipt on the page where the customer seems to have paid more than the levers imply.
- 150 min, ¥20,000 (September 8th), course plus repeat nomination plus wand. Board plus one lever gives ¥23,000. He paid ¥3,000 less.
- 120 min, ¥14,000 (September 10th), course plus nomination. The board says ¥20,000. ¥6,000 under, and there is no single published discount on this site that gets you there.
Five of nine reconcile to the yen. The other four scatter, and three of those four scatter in the customer's favor. Which tells you what the price board actually is at this shop: not a price, a ceiling. Nobody in this sample paid it. The median real spend across all nine — bookings between 100 and 180 minutes — is ¥17,000, room excluded.
One more artifact worth decoding. The headline coupon reads "18% OFF — 100 min ¥17,000 → ¥14,000." But the board says the 100 is ¥16,000, not ¥17,000. The missing thousand is the photo-nomination fee: the coupon quotes an all-in figure including one nomination, then takes ¥3,000 off it. That's the new-customer discount wearing a percentage costume, and it is the most honest coupon on the site precisely because it quotes the number you will actually hand over.
132 Names, and One Woman Holds a Sixth of the Reviews
The roster page lists 132 women, displayed a hundred at a time. Across that visible first hundred:
- 39 of them have no reviews at all — the board marks them 口コミ募集, "reviews wanted." Two in five.
- The 61 who do have reviews hold 474 between them, and the median among them is 3.
- The top name alone carries 83 — 17.5% of that entire pool. Behind her: 38, 37, 25, 24, 20, 19, 18, 16, 12. Then the cliff.
So the 626-review headline is doing a lot of load-bearing. Roughly a quarter of it belongs to women who aren't on the visible board any more, and of what remains, a sixth sits with one person. Read as a shop-quality signal, "626 reviews" is nearly meaningless. Read as a map of where the traffic goes, it's perfectly clear.
Ages across that first hundred run 23 to 57, mean 33.9, median 34 — a genuinely wide hitozuma spread rather than the twenty-somethings-in-wedding-rings you get at shops that use the word purely as marketing. Today's board carried 16 names, earliest starting at 10:00 and the last finishing at 01:30, with four women showing as immediately available inside a thirty-minute window around lunchtime. Two new arrivals are dated: one joined September 13th, one joined today, September 17th.
Getting Her There: Four Free Corners
Because there is no premises, access is a fee schedule, and this one is unusually legible.
Meeting fee — free at four places: the north exit in front of Don Quijote, the west exit in front of Sauna Karumaru, and pre-entry at hotels on the north, west or east side of the station. Then ¥1,000 for Otsuka (north exit by Mizuho, south exit by MUFG, or hotel pre-entry), Sugamo, and the 23 wards generally; ¥2,000 for everything further out.
Pickup fee — ¥1,000 in Toshima-ku, ¥2,000 across Itabashi, Nerima, Kita, Nakano and Bunkyo, ¥3,000 for the rest of the 23 wards and beyond — plus a note that choosing pickup adds another ¥1,000 on top. Read the two schedules together and the gap between meeting her yourself at a free corner and having her brought to you can be ¥4,000 on an otherwise identical booking, which on a ¥14,000 session is nearly a third again.
For home visits the shop is honest about the mechanics in a way most aren't: she travels by train and on foot, so a place far from a station may simply be declined, and whether she does home visits at all — and where — varies by woman. Not a policy. A person-by-person constraint.
Options are mostly free, which is rare: rotor, no-underwear meetup, no-bra meetup, immediate start and several others carry no charge. The paid list is short and cheap — ¥1,000 for vibe, pantyhose, panties or cosplay; ¥2,000 for facial, wand or remote-control egg. Individual women also sell their own personal options, one of which turned up on a real receipt at ¥1,000.
Hours are 10:00 to 05:00 Monday through Saturday, reception 09:00 to 03:00 — and Sunday stops five hours early, closing at 24:00 with reception shutting at 22:30. That Sunday cliff is the operational detail most likely to burn you. The number is 03-5928-4755, with the customary "saw it on Heaven" line, and there's a chat channel and net booking if you'd rather not say any of this out loud.
The Verdict
- Price transparency: ★★★★★ — six courses, both nomination tiers, a flat extension rate, two complete transport schedules and a full options list, published without euphemism.
- Value for money: ★★★★★ — a median real spend of ¥17,000 for a two-hour-plus booking in central Tokyo, before you have even chosen your coupon.
- Discount design: ★★★☆☆ — four well-targeted levers, but the no-stacking rule means the advertised maximum and the actual best deal are different products, and the shop never says so.
- Honesty of the headline: ★★☆☆☆ — "up to ¥5,000 OFF" is true, and also the fourth-best discount here, printed 132 times down the roster page.
- Roster depth: ★★★☆☆ — 132 names is a real bench, but two in five carry no reviews and the review weight is brutally concentrated.
- Access: ★★★★☆ — four free meeting points including hotel pre-entry on three sides of the station; minus a point for the pickup surcharge stacking on top of the pickup fee.
- Operational clarity: ★★★★☆ — everything is documented; the Sunday hours and the one-week review deadline are the two traps, and both are stated if you read to the bottom.
- Going back: ○ — the 150 on a fourth Thursday, booked in advance, met at a free corner, paid down with points.
What I keep turning over is how completely the pricing and the marketing here pull in opposite directions. Somebody in this organization built a course ladder where the cheapest minutes are precisely the ones that make the recommended course correct, priced the extension high enough to push you into booking properly, wrote four discounts that each buy a different specific behavior, and then attached a loyalty currency that quietly slips past their own no-stacking rule. That is careful work. And somebody else took the largest yen figure that architecture produces, put it in a starburst, and pasted it a hundred and thirty-two times onto a page where it is, mathematically, the worst offer in the room. The shop is a year old and clearly knows what it is doing. It just hasn't worked out yet that its best number is its smallest one.
