Mitsui Garden Hotel Yokohama Minatomirai Premier — Free Sky Onsen, Every Room Floor 21+, Brand-New in Minatomirai
Have you ever wanted a brand-new 5-star hotel with a free onsen, high-floor views in every single room — but without the eye-watering price tag of Yokohama's landmark tower hotels? Mitsui Garden Hotel Yokohama Minatomirai Premier, which opened in 2023, answers exactly that. Every room sits on floor 21 or above, the sky bath on floor 20 — called LA MAGNOLIA — is free for all guests with both indoor and outdoor pools, it's a 5-minute walk from Minatomirai Station, and it has even been selected for the Michelin Guide. A score of 9.2 from 6,556 reviews — the largest review sample among top-tier hotels in this area — tells you the quality has been consistent from day one.
Mitsui Garden Hotel Yokohama Minatomirai Premier stands in the heart of the Minatomirai district in Nishi-ku, Yokohama — a waterfront neighbourhood that packs Landmark Tower, the YOKOHAMA AIR CABIN, Cosmo World, and a pleasant bayside promenade all within easy walking distance. The hotel is a 5-minute walk from Minatomirai Station, and Landmark Tower — the landmark every visitor to Yokohama ends up at — is right nearby. It's a location that means you can do almost everything without catching a cab.
"Guests who've stayed here all say the same thing — the room is immaculate and feels genuinely new, and the sky bath on floor 20 is the real highlight: soaking in the outdoor pool after a day's sightseeing with Yokohama's city lights all around you."
What makes this hotel stand apart from others in the same area is the sky bath LA MAGNOLIA on floor 20 — two pools, one indoor and one open-air, free for all guests without exception. Standing waist-deep in hot water with Yokohama's skyline on every side is an experience that hotels at the same price point in most other Japanese cities simply can't replicate. Many guests say it was the single best moment of their trip, especially going up after a day's exploring when the city lights are at their best.
Another thing guests consistently praise is the fact that every single room is on floor 21 or higher, no exceptions. There are no ground-floor rooms to end up in by bad luck, and no rooms where the view is blocked by a neighbouring building. From the moment you open your door, you get an elevated view — regardless of which room category you booked or at what price. This is a genuine policy of the hotel, and it's why reviews practically always mention the view in glowing terms.
The hotel opened in 2023, which means everything is still in pristine condition — rooms, bathrooms, furnishings, lighting and all common areas. There are no accumulated signs of wear, and the clean, understated aesthetic typical of the Mitsui Garden brand creates a sense of calm that regular guests of Japanese hotel chains will immediately recognise. Add the Michelin Guide hotel selection recognition and there's nothing left to guess about the standard.
The Superior room at 24 m² is the standard room type here — not large by any stretch, but smartly designed to use the space efficiently. The honest trade-off is that the focus is on the view and the onsen rather than sprawling floor space, and most guests are fine with this because their downtime will be spent soaking on floor 20 anyway. Breakfast buffet is charged separately at around ¥3,520 per person — worth checking before you book whether you'd rather eat nearby.
To put it plainly: for a brand-new room, a free onsen, and high-floor views guaranteed in every room, ¥18,000 in the Minatomirai district represents real value against the competition charging many times that. A score of 9.2 from 6,556 reviews — more than any other top-tier hotel in this neighbourhood — isn't a fluke; it means the hotel has maintained its quality consistently since it opened.
If your Yokohama trip has a mid-range budget, you want a genuine Japanese onsen experience without travelling to a resort town, and you want to wake up to views of the bay and city skyline every morning — Mitsui Garden Hotel Yokohama Minatomirai Premier is a combination that's genuinely hard to beat at this price.
