Family Hotels Shinjuku: Roomy Stays for Kids

Which Shinjuku family hotel to book comes down to how many beds you need in one room, and whether you want a kitchen. Keio Plaza Hotel Tokyo (from ¥32,000) has a dedicated 46.3 m² family room that sleeps five and has two toilets; MIMARU Tokyo Shinjuku West (from ¥49,000) is the pick for a full kitchen and space for six; Citadines Shinjuku Tokyo (from ¥22,000) is the budget kitchenette option, with cribs at ¥550 a day. If you would rather have two rooms than one large one, Hilton Tokyo (from ¥45,000) has connecting rooms. All sit on the quieter west side, where the tower hotels have floor space that Shinjuku's smaller boutique properties cannot match.

Best Family Hotels in Shinjuku at a Glance

What Families Need in a Tokyo Hotel

A standard Tokyo hotel room runs around 18–22 m². That is fine for two adults, tight for two adults and a toddler, and not workable for a family of four without planning. Before you book, ask three questions: how many beds does the room have, is there a crib or can an extra bed be added, and is there laundry on-site?

• Floor space: Look for rooms above 30 m², or book connecting rooms if the standard category is all the hotel offers.
• Beds: Many hotels list "twin" rooms where both beds are singles pushed together — confirm the configuration if you have young children sharing.
• Laundry: A coin-operated laundry on the premises means you pack fewer clothes. Several of the picks below have this.
• Kitchen or kitchenette: Not essential, but a microwave and fridge cut breakfast costs significantly for a family of four in Tokyo.

Shinjuku's west side (Nishi-Shinjuku) concentrates the largest hotels and the most reliable family room stock. The east side has smaller boutique properties better suited to adults.

Hotels with Rooms for Four (or Connecting Rooms)

Keio Plaza Hotel Tokyo

The Luxury Family Room at Keio Plaza is the most family-specific option in the area. It measures 46.3 m², sleeps up to five guests across four beds and one sofa bed, has two toilets, and a double sink — genuinely useful when you have primary-school children who all need to brush teeth at once. The hotel sits a 5-min walk from Shinjuku Station's West Exit. Children's yukata and toothbrushes are provided on request. For families who cannot get the family room, the hotel also offers interconnecting rooms that link two standard guestrooms. Check rates.

Hyatt Regency Tokyo

Hyatt Regency Tokyo completed a major renovation in September 2025, refreshing over 90% of its 712 rooms. The renovation added a free shuttle bus between the hotel and Shinjuku Station that runs three times per hour from 08:00 to 22:00 — practical if you are travelling with tired children or loaded with luggage. The hotel has 22 distinctive room styles including studios and suites, and welcomes children. Cribs are available on request. The property is in Nishi-Shinjuku, roughly a 10-min walk from the station if you prefer not to wait for the shuttle. Check rates.

Hilton Tokyo

Hilton Tokyo is the connecting-room specialist in this lineup. The hotel can link two standard guestrooms into one unit, giving parents a separate sleeping space while children stay next door. Cribs are available; children under 6 stay free sharing existing bedding. It is a 10-min walk from Shinjuku Station West Exit. Families with strollers will find it easier to use Nishi-Shinjuku Station (Marunouchi Line, Exit C8) instead — a 2-min walk with barrier-free elevator access platform to street (confirmed July 2026). Check rates.

Apartment-Style Stays with Kitchenettes

MIMARU Tokyo Shinjuku West

MIMARU is an apartment hotel brand built specifically for families and groups. The Shinjuku West property opened in 2020 and is confirmed open for 2025 and 2026. All apartments include a fully equipped kitchen (hob, not just a microwave), a dining table, coin laundry on-site, and free Wi-Fi. Apartments sleep up to six guests. The location is a 6-min walk from Shinjuku Station or an 8-min walk from Tochomae Station (Toei Oedo Line, elevators available). Babycal stroller rental is available at this property and can be reserved online in advance (checked July 2026). Check rates.

For more apartment-style options across the area, see our guide to serviced apartments in Shinjuku.

Citadines Shinjuku Tokyo

Citadines Shinjuku Tokyo sits near Shinjuku-sanchome — a 5-min walk from Shinjuku Gyoenmae Station and 7 min from Shinjuku-sanchome Station. The 160-apartment property offers studios, one-bedroom, and two-bedroom units, all with kitchenettes (microwave, electric kettle, refrigerator, cooking utensils). Coin laundry is on-site, and the 24-hour front desk is bilingual. High chairs are available on request. Cribs (baby beds) are available at ¥550 per day — request one at the time of booking as quantities are limited. The Shinjuku-sanchome neighbourhood is quieter than the area around the main station, which makes a real difference when you are settling young children. Check rates.

Easy-for-Strollers Locations Near Step-Free Exits

Shinjuku Station is large and can feel overwhelming, but it has elevators at most major exit areas. A few practical notes for families:

• South Exit and New South Exit: These areas are the most stroller-friendly at Shinjuku Station, with open concourse space and accessible routes down to platforms. Busta Shinjuku (the long-distance bus terminal) and Takashimaya Times Square are both directly accessible from the New South Exit with no steps.
• West Exit: There is a barrier-free elevator route from the Yamanote Line inner tracks to the West Gate, but it routes through corridors and takes longer than the signage implies. Budget an extra 10 minutes if you are using a pram at peak times.
• Nishi-Shinjuku hotels (Keio Plaza, Hyatt Regency, Hilton, MIMARU): All are on the west side. The walk from the West Exit to each hotel lobby is on flat pavement with no stairs. The Hyatt Regency shuttle removes the walk entirely during daytime hours.
• Hilton Tokyo via Nishi-Shinjuku Station (Marunouchi Line, Exit C8): 2-min walk to the Hilton lobby; barrier-free elevator access platform to street (confirmed July 2026). Easier than routing through Shinjuku Station with a pram.
• Tochomae Station (Toei Oedo Line): MIMARU Tokyo Shinjuku West is an 8-min walk from Tochomae Station, which is less crowded than Shinjuku Station and has elevators.

Booking with Kids in Japan: Two Things to Know First

Rooms that vanish when you add children. Search a Japanese booking site with children included and the room count often drops sharply. This usually means the property never configured child occupancy or co-sleeping rules in the OTA's system — not that families are actually turned away. Before giving up, check the hotel's own site or send a direct email; every property in this article responds to English enquiries.

Co-sleeping rules vary by chain. At many Japanese business hotel chains, a child who shares an existing bed (co-sleeping, no extra bedding) stays free. At Toyoko Inn, children 12 and under co-sleep free (one child per bed; the free breakfast applies to co-sleeping children too). APA Hotel extends free co-sleeping to preschool-age children only. Dormy Inn charges a flat ¥3,000 per night for ages 3 through elementary school and is free for ages 0–2. Richmond Hotel allows free co-sleeping through elementary school age. Super Hotel allows free co-sleeping for preschoolers, but co-sleeping children count toward the room's official occupancy. Always confirm the current policy when you book, as rules can change.

Practical Tips: Cribs, Meals, Parks and Konbini

Cribs and extra beds

In Japan, cribs (called "baby beds" at most hotels) are generally available on request but not guaranteed. Book early and confirm at the time of reservation. Keio Plaza, Hyatt Regency, and Hilton Tokyo all have crib availability. Citadines charges ¥550 per day for a crib — confirm when booking. MIMARU apartments typically accommodate young children within the sleeping configuration rather than a separate crib.

Meals

A convenience store (konbini) will be within a 2-min walk of every hotel on this list. 7-Eleven, FamilyMart, and Lawson all carry hot foods, onigiri, sandwiches, yoghurt, and children's snacks from early morning. For sit-down breakfasts, Nishi-Shinjuku has family restaurant chains (Denny's Japan, Jonathan's) that open early and have high chairs. Keio Plaza, Hyatt Regency, and Hilton all have in-hotel restaurants with children's menus.

Parks nearby

Shinjuku Gyoen National Garden is the best open-air family space in the area — large lawns, picnic-friendly, and manageable for all ages. It is a 15-min walk or a short metro hop from Nishi-Shinjuku hotels, and about 10 min on foot from Citadines. Entry costs ¥500 per adult; children under 15 are free. The garden is open 09:00–16:30 (Oct 1–Mar 14), 09:00–18:00 (Mar 15–Jun 10 and Aug 1–Sep 30), or 09:00–19:00 (Jun 11–Jul 31); closed Mondays (or the following Tuesday if Monday is a public holiday) and Dec 29–Jan 3. For more on staying close to the garden, see our hotels near Shinjuku Gyoen guide.

Check-in times

Standard check-in across all five picks is 15:00. Early check-in can sometimes be arranged for a fee, or the hotel will store luggage if you arrive before the room is ready. If you are arriving direct from an international flight with young children, a pre-booked door-to-door airport transfer via Klook avoids the need to manage luggage and a buggy on the Narita Express or airport bus — worth considering when you have young children in tow. Call ahead to ask about early access too — most large hotels in Nishi-Shinjuku will do their best to prioritise families.

Getting around

Shinjuku is central enough that you can reach Harajuku, Akihabara, and Asakusa without a transfer from most platforms. MIMARU's stroller rental (via babycal) is worth considering if you have a baby but do not want to travel with a full-size pram. Many metro gates now have wide-barrier lanes that accept IC cards and accommodate folded strollers.

Trip Essentials for Shinjuku

Things worth booking before you land, all in English:

• eSIM — Airalo's Japan eSIM: install it at home and data works as soon as you switch off airplane mode at Haneda or Narita.
• Airport transfer — Welcome Pickups runs fixed-price door-to-door pickups from Haneda or Narita; Klook sells the airport bus and train tickets if you'd rather ride.
• Luggage storage — arriving before check-in? Radical Storage takes bags at shops near Shinjuku Station for a flat daily rate.
• Tickets and day trips — Klook covers teamLab tickets, Tokyo Skytree, and Hakone day trips; booking ahead skips the ticket-window line.

Related: Families who need two separate rooms should check Tokyo hotels with confirmable connecting rooms.

Two conditions decide a Shinjuku family room more than the address does: how small the room is and whether a child can share a bed. Both are set by the property, not by law.
