If you search for “Daiwa Roynet Hotel Tokyo Ariake (ダイワロイネットホテル東京有明)” and cannot find it on booking sites, it is not because the hotel moved. The hotel closed on March 31, 2024, and since December 20, 2024 the building has operated as a hotel under a different, international brand. You can no longer stay in Ariake under the Daiwa Roynet name. The chain itself, however, is alive and well: Daiwa Roynet Hotels Co., Ltd., part of the Daiwa House Group, operates 78 hotels across Japan (per the company, as of August 6, 2026), and properties in Wakayama and elsewhere are open as usual. This article uses public OTA data to cover the current situation in Ariake and listed prices if you stay there now, the options for staying at a Daiwa Roynet in Tokyo, and listed prices and guest reviews for the frequently searched Wakayama property.

Daiwa Roynet Hotel Tokyo Ariake Closed in March 2024

Daiwa Roynet Hotel Tokyo Ariake opened on October 1, 2018 with 368 rooms. About a 1-minute walk from both Ariake Station on the Yurikamome line and Kokusai-Tenjijo Station on the Rinkai Line, it was popular with visitors traveling to exhibitions at Tokyo Big Sight and concerts at Tokyo Garden Theater. HotelBank Editorial Team’s database holds 4,794 guest reviews for the hotel with an average of 4.67, one of the higher scores within the chain.

It ceased operations on March 31, 2024, and after renovation the building opened on December 20, 2024 as DoubleTree by Hilton Tokyo Ariake (17 floors above ground, 363 rooms) (opening announcement by Hilton and three other companies, in Japanese). Because the operating brand changed, the hotel is no longer covered by the Daiwa Roynet official website or member benefits. Guests who liked it can still return to the same building, but bookings are now made through Hilton channels.

What Does It Cost to Stay in Ariake Now? Listed Prices for Event Trips

If you are staying around Ariake for a trip to Tokyo Big Sight or Tokyo Garden Theater, the three main Ariake-area hotels whose listed prices HotelBank Editorial Team tracks (N=3, 1,888 rooms in total) showed, over the 62 nights from September 15 to November 15, 2026, all-plan average listed prices per night (per room, 2 guests, tax included) of about ¥7,600 to ¥33,900 by hotel, with the cheapest plans starting at ¥3,100; prices vary widely by hotel and date. DoubleTree by Hilton Tokyo Ariake, in the former Daiwa Roynet building, sits in a higher price band than these three, starting at ¥20,990 with an all-plan average of about ¥62,400 over the same 62 nights. For Koto Ward as a whole, the September 2026 listed price (area median of each hotel’s daily average, per room, 2 guests, tax included) is about ¥25,950 (N=70 hotels), 16.6% above the ¥22,249 of a year earlier (N=55 hotels). Prices tend to jump on days with large events, so the standard advice is to book early once your dates are fixed.

For business use, differences between properties become clear when judged on desk, connection, and quietness, as in this comparison scoring hotels near Toyama Station on how easy it is to join a meeting from the room (in Japanese).

Daiwa Roynet Hotel Wakayama: In Front of Wakayama Castle from ¥7,650

Daiwa Roynet Hotel Wakayama (ダイワロイネットホテル和歌山), a frequently searched property, is open. It opened in 2005 with 219 rooms and underwent a full renovation completed on April 19, 2024. The official room list shows doubles of 18.7 to 26.3 m², twins of 26.8 to 35.7 m², and a Family Four Room (58.3 m²) that sleeps up to four. Its biggest draw is its location in front of Wakayama Castle (about a 10-minute walk to the castle per the official guide), and 5 of its 8 room types are on the “Wakayama Castle side,” with views of the castle from the room.

Over the 62 nights from September 15 to November 15, 2026, listed prices were from ¥7,650, with an all-plan average of about ¥23,200 (per room, 2 guests, tax included). On 46 of the 62 nights, the cheapest plan of the day was ¥10,000 or less, and even the all-plan average is below the 4 Tokyo hotels in Table 1 (about ¥27,000 to ¥77,400). For a day-by-day look at when hotels in Wakayama Prefecture fill up over the five-day September holiday, see Wakayama Silver Week Peaks Midway.

Guests rate the hotel 4.56 on average (N=10,915 reviews, HotelBank Editorial Team research). In the 1,327 reviews from the last 24 months (September 2024 to September 2026) analyzed by our editorial team, 45% mention access to Wakayama Castle and other sights, 34% mention the view from the room, and 27% mention room cleanliness. Guests highlight the castle view, e.g. “Wakayama Castle seen from the room was lovely…” and “Having it while looking at the castle was the best…” (about the breakfast venue), and praise the rooms, e.g. “Very satisfied with the clean, spacious room…”. If the castle view is what you want, the safe bet is to pick a room type whose name includes “Wakayama Castle side” (such as Moderate Double or Standard Twin).

How to Choose When Booking: 3 Checkpoints

1. Compare prices shifted by one or two days

Listed prices swing widely on weekends and holidays, not only in event-driven areas such as Ariake but in regional cities too. Check the difference against the days before and after at least once.

2. Check early-booking and prepaid plans

At hotels offering early-booking or prepaid plans, the same room can cost a different amount depending on when you book and how you pay. If your dates are firm, compare the difference against the regular plan at least once.

3. Choose by room type

Room size varies widely by room type even within the same hotel. At Wakayama, the Standard Double is 18.7 m², while the Moderate Double on the Wakayama Castle side is 26.3 m². For two guests, check the price difference to the next room type up. For families, properties with connecting rooms, such as the two Kanazawa hotels introduced under “Further Reading” below, are also worth considering.

Methodology and Sources

■ Data sources

Listed prices are figures aggregated by HotelBank Editorial Team from public OTA data (by property for the three Ariake-area hotels, DoubleTree by Hilton Tokyo Ariake, the four Tokyo hotels, and Wakayama; area aggregate for Koto Ward). Review counts, averages, category scores, and mention rates are from guest review data researched by HotelBank Editorial Team (chain: 51 hotels, 157,872 reviews; Wakayama: N=10,915 reviews; mention rates analyzed over the last 24 months, N=1,327 reviews). The chain’s number of hotels and total rooms, the number of hotels in Tokyo, and Wakayama’s room types and sizes are from the respective official websites; the opening date and room count of the Ariake successor hotel are from the announcement by Hilton and partners (all checked by HotelBank Editorial Team on September 11, 2026).

■ Assumptions

Property-level listed prices cover the 62 nights from September 15 to November 15, 2026, per room for 2 adults, tax included. “Lowest” is the minimum of each night’s cheapest plan during the period; “all-plan average” is each night’s average across all plans, averaged over the 62 nights (aggregated September 11, 2026). Koto Ward is the monthly average of the area median of each hotel’s daily average; September 2026 mixes past dates and future dates (listed prices currently on sale).

■ Limitations

Listed prices are not actual transaction prices and vary by date, plan, and inventory. Treat the year-over-year change for Koto Ward as a rough guide, since the number of hotels covered differs (September 2025: N=55; September 2026: N=70). Review figures cover the 51 hotels whose reviews HotelBank Editorial Team aggregates, not all 78 official hotels. Review quotes are partial excerpts, translated from Japanese, from the analyzed reviews.
