Mitsui Garden Hotels is the hotel arm of Mitsui Fudosan, the developer behind Tokyo Midtown and much of Nihonbashi, and its hotels sit in the places that company owns: Ginza, Nihonbashi, Roppongi, Kyoto’s Sanjo and Shijo. The chain sells itself on three things: a large public bath on a high floor at 22 of its hotels, a breakfast built around local dishes, and rooms designed city by city. Its English pages also publish a full cancellation ladder and a set of house rules that most booking sites do not repeat.
This page is those rules in one place, from the official English FAQ, bath page, best-rate page and hotel regulations. Check-in times, room rates, breakfast prices and bath hours are set by each hotel and are not on the chain-wide pages, so they are not here.

Which Mitsui Garden Hotels have the public bath?
The FAQ answers this with a list, which is the single most useful line on the site, because the bath is the reason to choose this chain over a plain business hotel at the same price.
| City | Hotels with a large public bath |
|---|---|
| Tokyo | Nihonbashi PREMIER, Jingugaien Tokyo PREMIER, Ginza-gochome, Ginza Tsukiji, Shiodome Italia-gai, Toyosu PREMIER, Gotanda |
| Chiba | PRANA Tokyo Bay, Kashiwa-no-ha |
| Sapporo / Sendai | Sapporo, Sapporo West, Sendai |
| Nagoya / Kanazawa | Nagoya PREMIER, Kanazawa |
| Kyoto | Kyoto Shinmachi Bettei, Kyoto Sanjo PREMIER, Kyoto Shijo, Kyoto Kawaramachi Jokyoji |
| Osaka / Okayama | Osaka PREMIER, Okayama |
| Fukuoka / Taiwan | Fukuoka Gion, Fukuoka Nakasu, Taipei Zhongxiao |
22 hotels, as listed in the official FAQ on September 16, 2026.
Which Tokyo hotels do not have one?
By elimination from the same list: Ginza PREMIER, Millennium Tokyo (Ginza), Roppongi Tokyo PREMIER, Otemachi, Kyobashi and Ueno. If the bath is the point, book from the table above, not from the name.
Is any of them a real onsen?
One. The official bath page calls Kashiwa-no-ha, in Chiba, “the only pure-source, natural hot spring bath in a Mitsui Garden Hotel”. The rest are heated large baths, some with extras: Osaka PREMIER has an open-air bath and an artificial carbonated spring on its 16th-floor spa level; Okayama has cypress tubs and two miniature gardens themed on Momotaro and the Korakuen garden; Gotanda puts the bath on the top floor with views toward Shinjuku and Roppongi from the men’s side.
Which bath works with children?
PRANA Tokyo Bay, whose seventh-floor bath over Tokyo Bay is split into three temperature zones from hot to lukewarm, which the page says is so that guests with children need not worry. It is reached from Maihama Station by the free Tokyo Disney Resort partner-hotel shuttle in about 15 minutes; our Disney hotels guide covers the partner-hotel tier it belongs to. Whether a given bath admits children of the other sex, and up to what age, is not on the chain pages; our onsen rules guide explains why that varies by prefecture.

Official cancellation table from the FAQ. Individual plans may set their own terms.
What counts as a no-show?
The FAQ adds one line that matters for late flights: if there is no contact two hours after the expected arrival time, the booking may be counted as a cancellation. Give an arrival time you can keep, or message the hotel from the airport.
How does this compare with other chains?
It starts earlier and softer. Tokyu Stay charges nothing until two days before and then 50, 80 and 100 percent; Mitsui Garden adds a 20 percent step at three days. Dormy Inn refers you to each property. If your plans are loose, the three-day line is the one to put in the calendar.
How far ahead can I book?
It varies by hotel, and the chain says to ask the property. There is no waiting list. From abroad, the English booking page or a phone call to the hotel are the two routes the FAQ names.
Prices, taxes and the best-rate promise
Is there a service charge?
No. Listed rates include consumption tax and there is no service charge. What is added is the accommodation tax in Tokyo, Osaka, Kyoto, Kanazawa and Fukuoka, charged as a separate line, with a warning that other cities may levy it and rates can change without notice.
Is the official site really the cheapest?
The chain guarantees its official rate against websites operated in Japan under the same conditions: same hotel, dates, headcount, room type, payment method, cancellation terms, length of stay and check-in and check-out times, and the same extras. Excluded are corporate and member-only rates, travel-agent sales, point-and-voucher discounts on other sites, phone-only rates, auction sites and packages with transport or meals. It also says plainly that prices on other sites may be the same. Members of the free MGH Rewards Club get a further discount, and members booking by phone or in person get that day’s best rate too.
How do I pay?
Cash, credit card, traveler’s checks and vouchers the hotel accepts, at the front desk on check-in or whenever the desk asks. Which cards and which coupons each hotel takes is, again, per hotel. Extending a stay needs prior notice and settlement of what is owed so far.
Mitsui Garden Hotels house rules that carry a charge
What happens if I smoke in a non-smoking room?
You are billed the cost of putting the room back: deodorizing, and cleaning of bedding, curtains and wallpaper. The rule names electronic cigarettes explicitly, and cigarette butts found in the room count as evidence.
Can I refuse housekeeping for a week?
No. Even when a guest asks for no cleaning, the hotel cleans at least every three days for hygiene, and reserves the right to enter for maintenance, legal inspections and emergencies on other days. This is the opposite of Tokyu Stay’s request-only light cleaning, and worth knowing if you work from the room.
What else is on the list?
No animals except service dogs; nothing hung from the windows; no business use of rooms or the lobby; no gambling; valuables in the safe, with the hotel declining to hold art, antiques, instruments, computers, phones or documents with personal data. The lost-and-found rule follows Article 16 of the accommodation contract.
Can I get medicine at the desk?
No. The FAQ cites Article 24 of the Pharmaceutical Affairs Act and asks you to bring what you need; the desk will point you to a pharmacy.
The rooms and breakfasts the chain highlights
Which rooms are one of a kind?
Two, on the official room page. Millennium Mitsui Garden Hotel Tokyo in Ginza has a single Hakuza Gold Leaf room finished by the Kanazawa gold-leaf house Hakuza. Ueno has the Panda Room, themed on the neighbors at Ueno Zoo, down to the cushions and amenities. Shiodome Italia-gai puts a fabric deodorizer, clothes brush and shoe polish in every room for long business stays.
What is breakfast like?
A local-ingredient buffet, styled per hotel: Nihonbashi PREMIER serves Kaga cuisine from Asadaya, a Kanazawa house founded in 1867; Roppongi Tokyo PREMIER does a selectable main plus half buffet on the top floor with Tokyo Tower in view; Otemachi builds it around sandwiches on fresh bread. Whether non-guests can eat, and what children pay, is per hotel.
How many hotels are there?
The official list, read on September 16, 2026: 13 in Tokyo (Ginza PREMIER, Millennium Tokyo, Nihonbashi PREMIER, Roppongi Tokyo PREMIER, Jingugaien Tokyo PREMIER, Toyosu PREMIER, Otemachi, Kyobashi, Ginza-gochome, Ginza Tsukiji, Shiodome Italia-gai, Ueno, Gotanda), two in Sapporo, one in Sendai, four in Chiba including PRANA Tokyo Bay, Yokohama Minatomirai PREMIER, Kanazawa, Nagoya PREMIER, five in Kyoto, Osaka PREMIER, Okayama, Hiroshima, two in Fukuoka, Kumamoto, and Taipei Zhongxiao. Where it fits among Tokyo’s choices is in our where to stay in Tokyo guide.
What changes on February 26, 2027?
Osaka PREMIER becomes Osaka Nakanoshima PREMIER, and Osaka Dojimahama PREMIER opens, both on that date per the hotel list. Bookings made under the old name will refer to the same building.
How to choose among the Mitsui Garden Hotels
Is the PREMIER tier worth it?
The chain does not define PREMIER on its English pages beyond the names, so we will not either. What the official pages do show is where the extras sit: the top-floor baths at Gotanda and Osaka PREMIER, the Kaga breakfast at Nihonbashi PREMIER, the Tokyo Tower view at Roppongi Tokyo PREMIER. Read the property page for the hotel you are comparing; the word PREMIER alone does not tell you whether there is a bath.
Which one for Disney?
PRANA Tokyo Bay, the only Mitsui Garden on the free partner-hotel shuttle from Maihama, with the three-zone bath for children. It is a partner hotel, not an official Disney hotel, which changes what park benefits you get; the difference is in our Disney hotels guide.
Which one for a first Kyoto trip?
Four of the five Kyoto hotels have a public bath: Shinmachi Bettei, Sanjo PREMIER, Shijo and Kawaramachi Jokyoji. Kyoto Station is the one without. Kyoto also charges accommodation tax as a separate line, so the rate you see on the official site is not quite the rate you pay.
Does the chain have a loyalty program worth joining?
MGH Rewards Club is free and is the only way to get below the official best rate, according to the best-rate page; member-only rates and plans appear after login. The English FAQ does not describe points or tiers, so we do not describe them either. If you will stay more than once, joining before the first booking costs nothing and unlocks the member price that day.
What should I check before booking?
Four things the chain pages cannot answer for you: the check-in and check-out times of that hotel, the bath hours and whether children of the other sex may enter, the breakfast price and child rate, and which cards and coupons the desk accepts. Each is a property-page question, and the FAQ says so in those words.
Frequently asked questions

Is the bath a natural hot spring?
Are prices shown with tax and service charge?

Bottom line (2026). Pick a Mitsui Garden from the 22-hotel bath list, not from the name; expect 20 percent from three days out if you cancel; tell the hotel if you will be more than two hours late; and do not smoke in the room, e-cigarette included. Prices are tax-in with no service charge, plus city accommodation tax.
