Tokyo has a structural problem for families: the city's hotel stock is overwhelmingly built for one or two people, and "we're a family of five" usually means two rooms or a serviced apartment far from the action. Which is why karaksa hotel TOKYO STATION deserves a closer look than its modest mid-range profile suggests: 151 rooms five minutes from the Yaesu North Exit, with genuine quads, tatami family rooms sleeping six, and connecting rooms with two bathrooms. That combination barely exists this close to the shinkansen gates.
Where it sits in the neighborhood — and whether the station area suits your trip at all — is covered in our Tokyo Station hotels guide; this page is the hotel itself, fact-checked against its official site. Two things most reviews skip, both straight from the official room pages: most rooms have a shower booth, not a bathtub, and the kids-stay-free age doubles from 6 to 12 when you book direct.

The rooms: built for groups in a city that isn't
A Japanese stay-report on karaksa's tatami Japanese Family Room — the exact room type this section is about. The narration is Japanese, but you can see the futons laid out side by side across the tatami and judge the floor space for a group yourself.
Which room fits which group?
The official inventory, type by type: the backbone is Standard Twins (117 rooms across three variants — plain, with-sofa, with-extra-bed), comfortably above Tokyo's business-hotel norm, plus ten King Doubles and ten Compact Twins (13.6 m² — fine for one, tight for two). The reason to remember the name: five Family Quadruples (29.2 m², officially 1–4 people), five Family Triples, three Japanese Family Rooms (tatami and futon, low table with floor cushions — a 4-person and a 6-person layout, up to six) and connecting rooms — two rooms with an internal door and two bathrooms, officially up to five or six people without splitting the family across a corridor. If that's your exact problem, this is one of the few direct answers near the station.
The bathroom setup most reviews don't mention
Straight from the official room pages: standard rooms have a separated shower booth, sink and toilet — designed so several people can get ready at the same time, which genuinely matters with four people on a schedule — but no bathtub. The amenity list shows a bath only for the three tatami Japanese Family Rooms and the accessible room, and there's no public bath in the building. Also worth knowing before you book: every room is non-smoking (including heated tobacco and vapes — smoking rooms are on floors 4 and 9), and the windows don't open.
The details that punch above mid-range
What does ¥1,000 breakfast actually buy?
A light bakery-soup-salad buffet at the 1F 8S YAESU Café (31 seats, guests only): fresh-baked breads, soup, salad bar, daily side dishes, yogurt and coffee, 7:00–9:30 with last entry at 9:00. At a station where hotel breakfasts routinely run triple that, ¥1,000 is almost a rounding error — and the same café serves free welcome drinks 10:00–24:00 for guests. If you'd rather graze, Ramen Street is effectively your basement canteen, one station block away.
What's in the building?
Free Wi-Fi throughout, a 3F coin laundry corner, a 2F nursing room (24 hours, free), ice machines on 4F and 9F, a vending machine on 4F (no alcohol, and no shop in the building), and self-check-in kiosks at the front desk. Luggage storage is free at the 1F desk before check-in and after checkout — same-day pickup after checkout, and they'll hold bags longer free if you're coming back for another stay. You can also ship luggage ahead by courier, addressed care of the front desk.
Getting in from the airports
From Narita: the Narita Express runs direct to Tokyo Station in about 58 minutes, then it's the five-minute walk — our N'EX guide covers the train. From Haneda: Monorail to Hamamatsucho (~13 min) plus one Yamanote hop (~6 min) to Tokyo Station.
The fine print worth knowing
The 1:00–5:00 a.m. entrance lock
Not a curfew — the front entrance locks from 1:00 to 5:00 a.m. for security, and your room card key opens it (or use the intercom). It only bites if you go out at midnight without your key.
The two-tier kids rule
Standard channels: children 6 and under co-sleep free (one child per existing bed, up to two per room). Book direct on the official site and it becomes 12 and under free — and on breakfast-included plans the co-sleeping child eats free too. For a family of four with kids of 8 and 10, that single difference outweighs any OTA coupon we've seen. Add the other direct-booking perks — best-rate guarantee (claim within 24 hours of booking if you find it cheaper under identical conditions) and the free noon checkout — and the direct case makes itself.
The name trap, and a phishing warning
The chain runs karaksa hotel Colors Tokyo Yaesu nearby plus hotels in Ginza, Sapporo and Osaka, and the official site posts its own "make sure you come to the right building" warning — confirm TOKYO STATION / 1-5-3 Yaesu on your booking. Separately, in June 2026 the hotel published an alert about phishing messages sent through Booking.com's own messaging system steering guests to fake payment pages. If a "payment problem" message arrives, contact the hotel directly instead of tapping the link. (Housekeeping note: the operating company renamed itself Zymax International on July 1, 2026 — same hotels, same terms.)
Small print for specific travelers
Guests under 18 traveling without an adult need a signed parental consent form (one per minor). No pets. And if you're after the 10th-anniversary deals: the official site has been running anniversary plans in 2026, including a 30-days-ahead early-bird at up to 35% off — non-refundable, so date-certain travelers only.
Who it suits
Book it if: you're 3–6 people wanting one room near the shinkansen, you value language support that's engineered rather than hoped for (7-language site, multinational staff, a video-call interpreting service), or you want station-area logistics without station-area luxury pricing. Look elsewhere if: you want a nightly bathtub soak in a standard room (shower booths, remember — or book the tatami room), a big-hotel experience with bars and views, or rock-bottom solo pricing (the business chains undercut it). It's a focused tool, and for its target traveler, close to optimal.
Booking it right: why the official site quietly wins
For this hotel specifically, where you book changes what you get. Booking direct on the official site (karaksahotels.com) carries a stated best-rate guarantee, stretches checkout from 11:00 to 12:00 noon free, and — on breakfast-included plans — makes children 12 and under stay free when sharing existing beds (the standard policy is free co-sleeping only to age 6). A free membership adds 5% points on official bookings, and as of August 2026 the brand is running 10th-anniversary and 35%-off early-bird (30-day, non-refundable) plans. One warning straight from the hotel: it has publicly flagged phishing messages impersonating booking platforms — another argument for the official channel, and a reason to ignore the many unofficial "karaksa" lookalike sites in search results. Two precision notes for families: the connecting rooms are the Standard Twin types only (three variants; adjacent rooms joined by an inner door, two bathrooms, up to six guests) — the tatami and Family rooms don't connect — and don't confuse this hotel with its sibling karaksa hotel colors Tokyo Yaesu nearby, a mix-up the official site itself warns about.
(A different option on the same Yaesu side, our Yaesu Terminal Hotel guide covers the walking route from the bus terminal and how the building sits relative to the shinkansen gates.)

Bottom line (2026) — Real family rooms in central Tokyo: tatami rooms for six, quads, and connecting rooms with two bathrooms, five minutes from the Yaesu North Exit. Note that most rooms have a shower booth, not a tub, the kids-stay-free age doubles when you book direct on karaksahotels.com, and the operator’s own June 2, 2026 Booking.com phishing alert is one more reason to go direct.
