Japan’s largest hotel is the Shinagawa Prince Hotel (品川プリンスホテル) in Minato-ku, Tokyo, with 3,679 rooms. It spans four towers; counted as a single building, the largest in Japan is APA Hotel & Resort Yokohama Bay Tower (アパホテル&リゾート〈横浜ベイタワー〉) in Yokohama, Kanagawa, with 2,311 rooms. This article draws on the lodging properties tracked in Japan by MetroEngines Research, specifically the 38,010 properties and 1,597,005 rooms with confirmed sales on OTAs and other channels over the last 90 days, and presents a national Top 30 ranking of individual properties by room count. It also maps where Japan’s 139 large properties with 500 or more rooms are concentrated, and provides separate tables for the big resort hotels of Okinawa and Hokkaido.

Japan’s Largest Hotel Is Shinagawa Prince Hotel: National Top 30 by Room Count

The national Top 30 by room count is shown below. No. 1, Shinagawa Prince Hotel, consists of four towers: East Tower (1,015 rooms), N Tower (257), Main Tower (1,735) and Annex Tower (672), for a total of 3,679 rooms. With an aquarium, a bowling alley and a movie theater on site, this mixed-use complex is far larger than any other lodging property in Japan.

No. 2, APA Hotel & Resort Yokohama Bay Tower, opened in September 2019 with 35 floors and 2,311 rooms. At opening, its operator described it as “the largest in Japan as a single building.” Counted by property, Shinagawa Prince is No. 1; counted by building, Yokohama Bay Tower is. This is the first distinction to keep in mind when reading the ranking.

Below the top two, the 2,000-room class continues: Osaka Namba Ekimae Tower (2,055 rooms, opened December 2024), Tokyo Bay Makuhari (2,007 rooms) and Osaka Umeda Eki Tower (1,704 rooms, opened February 2023). Large tower hotels opened since 2019 are pushing up the top of the table. Among airport hotels, Villa Fontaine Grand Haneda Airport (1,557 rooms) ranks 6th, and Toyoko Inn Chubu International Airport 2 in Tokoname, Aichi (1,286 rooms) ranks 10th. Big hotels are found in more varied places than one might expect: not only city centers, but also airports and ski resorts (Naeba Prince Hotel, 1,216 rooms).

The Size Pyramid: 1,000+ Room Hotels Are 0.06% of Properties but Hold 2% of Rooms

The distribution by size tier makes it clear that the hotels at the top of the ranking are exceptions. Only 22 properties nationwide (0.06% of all properties) have 1,000 or more rooms, yet these 22 alone hold 31,705 rooms, or about 2.0% of all rooms counted. Even at 500+ rooms there are just 139 properties (0.37%), but they account for 106,732 rooms, or 6.7%.

At the other end, there are 29,485 small properties with 49 rooms or fewer, making up 77.6% of all properties but only 20.9% of rooms. Japan’s lodging supply has a two-layer structure: overwhelmingly small by number of properties, but carried by mid-size and large hotels by number of rooms. In fact, the 3,144 properties with 150+ rooms (8.3%) hold 48.7% of all rooms, which means the capacity for groups, sports events and MICE is concentrated in fewer than one in ten properties.

Where the Big Hotels Are: The Uneven Geography of 139 Properties with 500+ Rooms

Broken down by prefecture, just three (Tokyo with 40, Osaka with 26 and Chiba with 21) account for 87 properties (62.6%) of the 139 with 500+ rooms. They are followed by Hokkaido (10), Aichi (7), Fukuoka (7) and Kanagawa (5). Only 20 prefectures have even one property with 500+ rooms; the remaining 27 have none.

Chiba’s breakdown is especially telling. Of its 21 properties, 14 are in Urayasu, 6 in Narita and 1 in Makuhari (Mihama-ku), clustered neatly around three hubs: a theme park, an international airport and a convention center. Osaka’s 26 show a similar pattern: 7 in Chuo-ku and 6 in Kita-ku in the city center, plus 4 in Konohana-ku (next to a major theme park) and 3 in Izumisano (next to the airport). Big hotels sit at two poles: in dense city-center commercial districts and next to facilities that bring in large numbers of visitors. Tokyo’s 40 are spread across rail terminals and the waterfront: Minato-ku (9), Shinjuku-ku (9), Koto-ku (6), Chiyoda-ku (4) and Toshima-ku (4).

Why Large-Hotel Stock Matters: Groups, Event Accommodation and MICE

A room-count ranking is more than a size contest. Properties with more than 150 rooms are scarce inventory that can absorb group demand in one block, such as school trips, sports tournaments and academic conferences. A group of 100 can be housed in a single property, but for a group of 500, securing several 150-room hotels versus one 500-room hotel makes a big difference in the work of allocating accommodation. For a view of how many rooms surround major venues, our comparison of hotel supply around six exhibition venues also covers how much demand rises during events.

Seen this way, it is no coincidence that many of the top properties include banquet and convention facilities. For example, Ryukyu Hotel & Resort Nashiro Beach (琉球ホテル&リゾート 名城ビーチ) in Itoman, Okinawa (443 rooms, opened July 2022) has a 1,130-square-meter grand ballroom, one of the largest in the prefecture, that seats up to about 1,000 people. The ability to combine lodging with meetings and banquets on a single site is a key source of value for large properties.

Conversely, the 27 prefectures with no property of 500+ rooms must combine multiple properties to host large tournaments or conventions. For regions seeking to attract major events, this distribution of room stock is a basic condition worth understanding. For areas considering large new developments, too, the amount of inventory in properties with more than 150 rooms is a factor that sets the ceiling on demand.

Okinawa Hotel Ranking by Room Count: Top 12 Large Resorts

Okinawa has 3 properties with 500+ rooms (1,875 rooms in total). The largest in the prefecture is Rizzan Sea-Park Hotel Tancha Bay (リザンシーパークホテル谷茶ベイ) in Onna Village, with 826 rooms, large enough to rank near the top nationally. No. 2 is Loisir Hotel Naha (533 rooms) and No. 3 is Okinawa Kariyushi Beach Resort Ocean Spa (516 rooms).

What sets Okinawa apart is its deep layer of mid-to-large resorts in the 300-room range. At 300+ rooms the prefecture has 24 properties (9,392 rooms), spread in three directions: the west-coast resort strip of Onna and Yomitan villages, the southern area around Itoman, and Ishigaki Island. While large hotels nationally cluster in cities and at airports, Okinawa is one of the few prefectures where big hotels work as beach resorts. For what is being added to the prefecture’s supply right now, see our analysis of Okinawa’s 2,842 new rooms by hotel type.

Hokkaido’s Top 10 Large Hotels: Sapporo Concentration and Resort Destinations

Hokkaido has 10 properties with 500+ rooms (5,903 rooms), ranking next after Tokyo, Osaka and Chiba. Most are in Sapporo, and the largest in Hokkaido is APA Hotel & Resort Sapporo with 903 rooms, followed by Jozankei View Hotel (646 rooms) and Sapporo Hotel by Granbell (605 rooms), which opened in 2024.

Outside Sapporo, 500-room-class properties stand in snow resorts such as Shimukappu, Rusutsu and Niseko. These large hotels stay viable by combining winter ski demand with off-season MICE and training-camp demand, the same model as Naeba Prince Hotel in Niigata (1,216 rooms) and Shiga Kogen Prince Hotel in Nagano (666 rooms).

Summary: Three Ways to Read the Ranking

First, “Japan’s No. 1” depends on how you count. By property it is Shinagawa Prince Hotel (3,679 rooms); by building it is APA Hotel & Resort Yokohama Bay Tower (2,311 rooms). Because rankings shift depending on how multi-tower properties are treated, the unit of comparison must always be stated.

Second, large hotels are exceptional. Only 22 properties (0.06%) have 1,000+ rooms, and even at 500+ rooms there are just 139 (0.37%). Yet they hold 6.7% of rooms, and at 150+ rooms the share rises to 48.7%. The distribution of properties and the distribution of rooms look completely different.

Third, big hotels are extremely unevenly located. Only 20 prefectures have a property with 500+ rooms, and 62.6% are concentrated in Tokyo, Osaka and Chiba. A common pattern is visible: large hotels cluster next to facilities that bring in large numbers of visitors, such as the theme park, airport and Makuhari in Chiba, and the city center, theme park and airport in Osaka. Okinawa and Hokkaido differ from this urban pattern, supporting large properties through beach and snow resorts, which directly reflects differences in regional demand.

Note that published room counts change with extensions, renovations and the consolidation of buildings. Figures in this article are as of September 2026, and properties renamed through rebranding (such as Phoenix Seagaia Ocean Tower (フェニックス・シーガイア・オーシャン・タワー) in Miyazaki, 734 rooms) are listed under their current names.
