Overview
Underground passages connect Mitsui Garden Hotel Nihonbashi Premier with both Shin-Nihombashi Station and Mitsukoshimae Station. This weather-protected approach is the defining advantage, particularly when you're arriving with luggage or planning to use several rail and subway lines.
There's more here than a basic station-side room. Guest rooms occupy the upper part of the building, while the ninth floor brings together the lobby, Japanese dining, a bar, and a public bath.
Rooms
Rooms range from the 20-square-meter Standard Double to the 55.9-square-meter Junior Suite. The 23.5-square-meter Superior Queen provides a middle option for couples, while Superior Twins measure 26.4 square meters and corner twins expand to 29.5 square meters. Three-bed rooms accommodate small groups.
All rooms are non-smoking. Most categories separate the bath, toilet, and washroom, although the accessible room is an exception. Check the exact floor plan before booking if you need three beds, more open luggage space, or an accessible layout.
Facilities
The guest-only public bath is on the ninth floor and is free to use. Cypress headrests, wood details, and a lie-down bath provide a calmer end to the day than another trip across town. Current hours are 3:00 PM to 1:00 AM and 6:00 AM to 9:00 AM.
A first-floor information counter can help with local sightseeing and dining questions. This isn't a resort with an extensive recreation program, but the public bath and high-floor common spaces give the stay more character than a purely functional business hotel.
Dining
Nihonbashi Asada serves Kaga cuisine on the ninth floor. Breakfast is a Japanese buffet centered on rice, soup, seasonal vegetable dishes, and food prepared in the open kitchen, with some Western items also available. The restaurant returns for Kaga-style lunch and dinner.
Bar Matsu provides a separate evening option with counter and sofa seating, city views, and a terrace used when weather permits. Breakfast and the bar cost extra unless they're included in the booked rate, so check the plan rather than assuming either comes with the room.
Location and transport
The hotel is in Tokyo-Nihonbashi, beside the shops and restaurants of Coredo Muromachi. Shin-Nihombashi is the JR option: the Sobu Rapid Line reaches Tokyo Station in one stop and continues east toward Chiba. Mitsukoshimae adds the Ginza Line toward Ginza, Ueno, and Asakusa, plus the Hanzomon Line toward Otemachi, Shibuya, and Oshiage.
Tokyo Station's Nihonbashi Exit is about 11 minutes away by the shortest walking route, which can be useful for Shinkansen departures when the one-stop JR ride isn't convenient. Kanda Station is about seven minutes away, and Nihombashi Station is about eight minutes from the hotel.
Airport access
Allow roughly 40 to 50 minutes from Haneda Airport and 70 to 110 minutes from Narita Airport. These are journeys across the city rather than a scheduled hotel-door airport shuttle, and the best route depends on the timetable, arrival terminal, and amount of luggage.
Selected Sobu Rapid Line trains from Shin-Nihombashi continue to Narita Airport, but not every eastbound service does. Tokyo Station provides a wider choice, including Narita Express trains and other airport connections. Recheck the live route before departure.
Why stay here
Direct underground links to both JR and Tokyo Metro simplify luggage-heavy arrivals and travel across Tokyo, with the public bath waiting at the end of the day. Tokyo Station remains close for Shinkansen journeys, although staying inside the station complex will be simpler for a very early train.
Outside, Nihonbashi combines historic department stores and specialist food and craft shops with modern Coredo Muromachi. Fukutoku Shrine, the Mitsui Memorial Museum, and Nihonbashi Bridge provide easy cultural stops without turning the neighborhood into a crowded nightlife district.
Good to know
Check-in begins at 3:00 PM, and check-out is by noon. There is no parking on the hotel premises, though nearby paid options are available.
The underground connection has one timing caveat: the escalator route between the hotel basement and first floor closes from midnight to 7:00 AM. During those hours, use the street-level entrance instead.
