First, Check Whether It Fits Your Trip

The 40 sqm family room has two beds plus a bunk bed, with a four-single-bed option and a 42 sqm Japanese-style room as well.
Every room has a kitchen and dining table, good for the whole family eating together; laundry is shared coin-operated equipment.
About 10 minutes from Shinjuku Station’s South Exit and about 8 minutes from Tochomae A2; with children and luggage, allow extra time.

For a family of four in Tokyo, my first thought is not which hotel is prettiest, but whether everyone can sleep well in the same room, whether breakfast can be eaten sitting down, and where four people’s luggage goes. MIMARU Tokyo Shinjuku West is an apartment-style hotel that answers those needs directly.

Rooms from 40 square meters, with a kitchen, dining table, and beds for several people, mean a trip does not have to be every meal eaten out, and children do not have to be put in a separate room. For families with children, groups of three or four friends, or multigenerational travelers, this living setup is often more useful than one more shared facility.

I would first flag its trade-off: the hotel is not right beside the JR Shinjuku Station exit. Some guests find it convenient, while others find the daily walk back far, especially when carrying many things after shopping. It is worth choosing because you will use the in-room space, not just because you want the least walking every day.

Transport: About 10 Minutes from the Shinjuku South Exit — Plan the Luggage-Haul Leg First

The official listing gives about a 10-minute walk from the JR Shinjuku Station South Exit and about 8 minutes from Tochomae Station Exit A2. That is a street-level route reference; time to find the exit from the platform, with children or large suitcases, must be added on top, and I would allow extra margin on arrival day and on days taking long-distance trains.

If you need a lift or a step-free route for a stroller, first use the hotel website’s universal-design transport map, then follow the day’s station signs to street level. In general, A2 or the South Exit does not guarantee the route with the fewest steps throughout; the entrance and actual route should still be confirmed against your own mobility needs.

Some guests use the airport bus stop at the nearby Shinjuku Washington Hotel, but that is not a direct stop at MIMARU’s door. If you plan it that way, before setting off, check whether the bus stops there, its timetable, and the luggage-walking route, then decide whether it saves effort compared with taking the train.

Choose Rooms by Sleeping Arrangement First: Bunk Beds, Four Single Beds, and Tatami Differ

Room type	Size / beds	How I would choose
Family Apartment	40 sqm; 2 single beds + 1 bunk bed	A family of four, where children can use the bunk beds appropriately
Apartment 4 Single-Beds	40 sqm; 4 single beds	Four adults wanting a bed each
Japanese Apartment	42 sqm; 2 single beds + 2 Japanese futons	For those who like tatami and accept laying out and putting away futons
Superior One-Bedroom Apartment	58 sqm; 6 single beds	For six traveling together, check the partitions and circulation first
Deluxe Japanese Apartment	60 sqm; 2 single beds, 2 futons, 1 bunk bed	For multigenerational or six-person stays, sleeping arrangements must be assigned in advance

I would first ask everyone which beds they can accept, then look at room size. Four adults each needing an independent bed makes four single beds the more direct choice; if children like bunk beds, look at the Family type. Small children should not climb to an upper berth on their own, and older guests may also find sleeping on the floor inconvenient — futons and bunk beds are not decisions to make just because they look cute in photos.

The official room types also list capacity for children under 6 using existing beds, but a child place is not an extra bed given free. From age 7, guests count as adults, so fill in everyone’s ages clearly when booking, then confirm the actual bed count. Cribs and other borrowed items should also be asked about in advance; do not take display photos as a guarantee.

The kitchen and dining table are important equipment in every room, with an IH cooktop, fridge, microwave, and basic cookware and tableware. Buying fruit, milk, cooked food, or simple ingredients to bring back lets the whole family sit down to eat instead of putting everything on the beds. I would first cook one simple meal, rather than spending too much trip time on cooking.

The division of bathroom, wash area, and toilet is very helpful when several people get ready in the morning. Even large room types, with more beds, still have only one bathroom and one toilet, so everyone takes turns; do not assume a six-person room has two full bathrooms.

No In-House Breakfast: The Kitchen and Nearby Shops Are the Alternative

This property does not provide a hotel breakfast; before choosing it, I would first accept that. Its advantage is the in-room kitchen and dining table: bread, fruit, or simple ingredients can be bought the night before, so the whole family does not have to go out immediately in the morning to find a restaurant.

I would split breakfast into two kinds: on rushed days, eat simply in the room; on a day you want to start slowly, go out for coffee or a set meal. When shopping, buy according to fridge capacity and headcount; there is no need to turn the trip into cooking three meals a day, and alternating eating out with eating in the room is more relaxing.

If you care a lot about a hotel buffet breakfast and want someone to prepare plenty of hot food every day, this property is not in the same direction. When comparing budgets, count family breakfast and shopping time too, not just room rates.

Consecutive Stays Make a Difference: Plan Kitchen, Laundry, and Cleaning Rhythm Together

A large room can be used for one or two nights too, but if you leave early and return late every day, the kitchen and dining table may go unused. Staying three nights or more brings out its strengths more: one evening not eating out, laundry back at the room, and the whole family sitting down to plan the next day, giving the middle of the trip a bit of living breathing room.

The official room types state clearly that there is no in-room washer-dryer; the building provides shared coin laundry. That differs from apartments where every room has a washing machine, and washing and drying require waiting; I would leave one evening less packed, sorting laundry first and then what to take the next day.

Cleaning does not follow a daily full sheet-change pattern. The official description schedules sheet changes, bed-making, and vacuuming from check-in on days 4, 7, 10, and so on; other daily replenishment and rubbish handling can be explained at check-in. Anyone wanting a full daily clean should ask directly about extra arrangements before booking.

Guests generally like the space, facilities, and service, though some still find the shops and station far. With children napping or returning to the room several times after shopping, count that walk into each day’s plan; do not underestimate, just because the room is large, the energy a family spends going back and forth.

How to Plan Your Days: Tocho, the Park, and South-Exit Shopping in Stages

The hotel is on the south side of Nishi-Shinjuku, so Tocho and Shinjuku Central Park can fill a slower half-day, while shopping around the Shinjuku South Exit gets a separate stretch, with purchases dropped back at the hotel when bags pile up. For children, alternating the park and in-room rest between shopping is more comfortable than walking department stores all day.

For a three-night family trip I would plan it this way: on the first night, get to know the supermarket and convenience stores and buy a small breakfast; on the second day, go out and enjoy Tokyo, then eat a simple dinner back in the room; on the third day, visit the park or Tocho in the morning and shop around the South Exit in the afternoon. Sorting the next day’s clothes and luggage each night means four people do not have to hunt for things together in the morning.

This kind of room also suits friends traveling together, especially those who want to chat and eat late-night snacks without splitting rooms. But sharing a kitchen and bathroom among several people calls for dividing tasks first — who clears the tableware, who showers first, what time lights go out — and that often matters more than a few more square meters of room.

Pros and Cons: Trading Walking Distance for Whole-Family Living Space

Aspect	Pros	Trade-offs to accept
Rooms	From 40 sqm, with multiple beds for sharing one room	Bunk beds and futon sleeping must suit your companions
Food and drink	Kitchen and dining table fully equipped for simple cooking	No in-house breakfast; shopping or eating out needed
Living with several people	Bathroom, wash area, and toilet divided	Even large room types still share one bathroom and toilet in rotation
Consecutive stays	Shared laundry and living facilities are practical	No in-room washing machine; cleaning is not a full daily clean
Transport	The South Exit and the Tocho park area are walkable	Carrying shopping bags and dragging suitcases makes the distance felt

My Verdict: Well Worth Comparing If Family and Friends Will Use the Dining Table and Kitchen

I would recommend it to groups of about four traveling together who hope to share a room while keeping living space. Choosing four single beds, bunk beds, or tatami sleeping first, then looking at guest-count and age rules, is more practical than choosing only by size or pretty photos.

If you are staying only one night, rushing to trains every day, or care most about stepping straight out of the station and a buffet breakfast, I would compare other types again. This property is most suited to those willing to walk a stretch, in exchange for a Tokyo base where the whole family can sit down to eat, sort luggage, and rest well.
