Tokyo Hotel Connecting Rooms: Which Ones Can You Book as a Pair?

In Tokyo, “connecting rooms” is used for two different things. A few hotels sell two rooms joined by a door (or side by side) as their own room type, so the pair is what you book. Most others only take a connecting request, which the hotel tries to meet but does not promise, and some have no connecting rooms at all.

Below are the Tokyo connecting and adjoining room types we could confirm on the hotels’ official pages, followed by hotels where it is only a request and hotels that say they have none.

Quick answers

A bed or futon for each of 4

Washing machine in the room

Full kitchen with a stove

Two rooms sold as one room type*

Connecting only on request

  • Hilton Tokyo – Connecting Rooms (2 rooms via Happy Family Plan)

Lists are built from what the hotels state. A room with a “Not confirmed” value is left out of a list rather than assumed.

* Sold as a pair: Our reading, not the hotel’s wording: when two connecting or adjoining rooms are sold as their own room type, booking that room type should get you both rooms together, unlike a “connecting request”. Most hotel pages do not use the word “guaranteed”, so confirm with the hotel if it matters.

Which one fits your family?

  • You are 6 to 9 people, or want two bathrooms and a kitchen: A MIMARU connecting apartment (Akasaka, Ikebukuro, Ueno East and others).
    Two apartment units joined by a door, sold as one room type for 8 adults (9 at Nihombashi Suitengumae) plus up to 4 children aged 6 or under, each unit with a kitchen.
  • You are 4 or 5 and want a washer-dryer in the room: Tokyu Stay Shinjuku Eastside – Adjoining Room A (4) or B (5).
    Two adjoining rooms sold as one room type, with a washer-dryer and kitchenette. Room B has three beds and a futon, so five people only fit if a preschool child shares a bed.
  • You want a full-service hotel with two connected rooms: Keio Plaza Hotel Tokyo – Deluxe Select Connecting Room.
    Two connected rooms (71 m² in total) sold as one room type for 3–4 guests. For a fifth person, a preschool child would have to share a bed under the hotel’s rule.

The differences that matter

Every connecting room type we found in Tokyo

MIMARU sells connecting apartments at six Tokyo locations: Akasaka, Hatchobori, Ikebukuro, Nihombashi Suitengumae, Tokyo Station East and Ueno East (see MIMARU hotels compared). Tokyu Stay Shinjuku Eastside sells Adjoining Room A and B (see Tokyu Stay hotels compared). Citadines Shinjuku sells “Stay Connected 3 Beds” for up to 5 guests, with the 5th guest charged extra. Keio Plaza Hotel Tokyo sells a Deluxe Select Connecting Room. The table above shows the ones we have full room records for.

Request only: Hilton Tokyo

Hilton Tokyo (Nishi-Shinjuku) does not list a connecting room type. Its Happy Family Plan includes connecting rooms when you book two rooms, by advance request to the hotel; the plan page says this may not be possible depending on circumstances. See Hilton Tokyo family rooms.

No connecting rooms: HOTEL GROOVE SHINJUKU and Hotel Gracery Shinjuku

The official FAQs of HOTEL GROOVE SHINJUKU and Hotel Gracery Shinjuku both say they have no connecting rooms. At GROOVE a family of 5–6 would need a single large room such as the Japanese Suite. At the MIMARU locations without a connecting room type, MIMARU’s FAQ says requests for adjacent rooms are taken but not guaranteed.

Connecting vs adjoining

Connecting rooms share an internal door. Adjoining rooms are next to each other, and may or may not have a door between them. Tokyu Stay calls its Shinjuku Eastside pair “Adjoining”; a 2022 Tokyu Stay press release says the door between the two rooms can be left open, but does not distinguish Room A from Room B, so ask the hotel if that matters with young children.

Before you book

  1. Search for the pair room type by its exact name (for example “Connecting Japanese Apartment” or “Adjoining Room B”) on the hotel’s own site; booking “2 rooms” does not get you the pair.
  2. Check the child rule: MIMARU does not count up to 2 children aged 6 or under per unit; Tokyu Stay and Keio Plaza only let preschool children share a bed for free.
  3. Count beds across both rooms, not only the maximum guests.
  4. A connecting request (Hilton Tokyo’s plan, or adjacent rooms at MIMARU) is not a booking condition. Book a pair room type or a single room that fits everyone if you must be together.
