Sunroute Plaza Tokyo (サンルートプラザ東京) was renamed Tokyo Bay Maihama Hotel First Resort (東京ベイ舞浜ホテル ファーストリゾート) on October 1, 2019, and it is still operating in the same building (1-6 Maihama, Urayasu, Chiba). It did not close and was not rebuilt. The hotel ended its franchise agreement with the Sunroute chain and moved into the Tokyo Bay Maihama Hotel group brand, so this was a rebrand. It is still a Tokyo Disney Resort Official Hotel.
Based on online travel agency (OTA) listed prices as of October 14, 2026 (one room, two guests, tax included), the cheapest weekday (Mon–Thu) plan has a monthly median ranging from the low ¥20,000s to the low ¥30,000s, and Saturdays from the mid-¥30,000s to the high ¥40,000s. This article is for readers searching under the old name. It covers why the name changed, what the hotel is like today, listed prices by day of week and month from October to March, and when to book.
- — The former Sunroute Plaza Tokyo is today’s Tokyo Bay Maihama Hotel First Resort: it left the Sunroute chain and changed its name on October 1, 2019. It did not close and is still operating in the same building (1-6 Maihama, Urayasu, Chiba).
- — 696 rooms in 3 wings: as a Tokyo Disney Resort Official Hotel, it is served by a free shuttle bus from the South Exit of JR Maihama Station. The operator is First Resort Co., Ltd. (formerly Plaza Sunroute Co., Ltd.).
- — Cheapest weekday plan: median ¥25,920; Saturday: ¥41,040: listed prices for stays from October 15, 2026 to March 31, 2027, one room, two guests, tax included (as of October 14, 2026; weekdays N=83 nights, Saturdays N=23 nights).
- — The cheapest nights are January–February weekdays and Sunday nights: the median weekday low is ¥23,760 in January and ¥25,920 in February. Sunday nights are also ¥25,920 (N=20 nights), on par with weekdays. Saturdays in November and March, at ¥49,680, are the most expensive of the six months.
- — The most affordable of six large hotels in Maihama: the median weekday low at the five nearby hotels ranges from ¥32,400 to ¥35,530. Over the New Year holidays, even the cheapest plans run ¥40,000–¥60,000+.
The Answer: Former Sunroute Plaza Tokyo = Today’s Tokyo Bay Maihama Hotel First Resort
| Item | Details |
|---|---|
| Former name | Sunroute Plaza Tokyo (opened July 20, 1986) |
| Current name | Tokyo Bay Maihama Hotel First Resort |
| Date of name change | October 1, 2019 |
| Address | 1-6 Maihama, Urayasu, Chiba (same building and site) |
| Operator | First Resort Co., Ltd. (formerly Plaza Sunroute Co., Ltd.) |
| Designation | Tokyo Disney Resort Official Hotel |
| Status | Operating (as of October 2026, rooms are listed for booking through March of next year) |
Source: the operator’s 2019 announcement; the operator’s company profile (checked October 2026); hotel listings on the Tokyo Disney Resort official website. Operating status: HotelBank Editorial Team research
The old name still appears in searches because the hotel operated under it for 33 years. Searching for “Sunroute Plaza Tokyo” on booking sites or map apps often leads to the page under the current name. When booking or contacting the hotel, searching under the new name is the most reliable approach.
How the Name Changed (Timeline)
| Date | Event |
|---|---|
| December 1982 | Operating company Plaza Sunroute Co., Ltd. founded |
| July 20, 1986 | Sunroute Plaza Tokyo opens as a member of the Sunroute hotel chain |
| March 2007 | Sister property Tokyo Bay Maihama Hotel opens |
| October 2010 | Sister property Tokyo Bay Maihama Hotel Club Resort is rebranded |
| Spring 2019 | Guest room renovation completed ahead of the rebrand |
| October 1, 2019 | Franchise agreement with the Sunroute chain ends; hotel renamed Tokyo Bay Maihama Hotel First Resort. The operator also changes its name to First Resort Co., Ltd. |
Source: the operator’s 2019 announcement; company history in the operator’s company profile (checked October 2026)
With the rebrand, First Resort became the group’s third Maihama hotel, after Tokyo Bay Maihama Hotel and Tokyo Bay Maihama Hotel Club Resort. The name changed, but the building, the site and the Official Hotel role carried over. HotelBank covered the rebrand announcement in Japanese at the time (January 2019).
Conversions like this, from an old name to a new brand, are still happening across Japan. For hotels renamed in 2025, Top 5 Business Hotels Rebranded or Reopened After Renovation in 2025 (innippon, in Japanese) lists old and new names side by side. HotelBank has used the same approach, tracing a hotel from its old name to its current name and prices, for Yukai Resort (now Ooedo Onsen Monogatari) and Sapporo Tobu Hotel (now Fairfield by Marriott Sapporo).

The 2019 announcement gave the shuttle bus ride from Maihama Station as “about 4 minutes.” Some current guides say about 10 minutes, and traffic also affects it. Allow extra time in the evening, when park visitors are heading back. Shuttle timetables are on the hotel’s official website.
Guest ratings are steady. In reviews compiled by the HotelBank Editorial Team (36,821 in total, of which N=5,234 fall in the most recent 24 months, October 2024–October 2026), the hotel scores out of 5: staff 4.33 (N=1,241), cleanliness 4.27 (N=2,596), location 4.27 (N=1,034), breakfast 4.21 (N=986) and service 4.19 (N=2,860). Staff and cleanliness are its strongest points.
How Much Does It Cost? Listed Prices by Day of Week and Month (October–March)
We compiled OTA listed prices as of October 14, 2026 for each stay date from October 15, 2026 to March 31, 2027. National holidays, nights before holidays and the New Year period (December 28 – January 3) are excluded from weekdays and reported separately.
| Stay month | Weekday low (median) | Weekday low (range) | Saturday low (median) | Saturday low (range) | Average listed price, weekday / Saturday |
|---|---|---|---|---|---|
| October 2026* | ¥21,600 | ¥17,280–¥34,560 | ¥34,560 | ¥33,480–¥36,720 | ¥47k / ¥63k |
| November 2026 | ¥31,320 | ¥24,840–¥35,640 | ¥49,680 | ¥43,200–¥74,520 | ¥55k / ¥85k |
| December 2026 | ¥27,000 | ¥20,520–¥30,240 | ¥45,360 | ¥42,120–¥45,360 | ¥48k / ¥70k |
| January 2027 | ¥23,760 | ¥20,400–¥25,920 | ¥35,640 | ¥34,560–¥37,800 | ¥40k / ¥57k |
| February 2027 | ¥25,920 | ¥25,920–¥27,000 | ¥36,720 | ¥36,720 | ¥44k / ¥58k |
| March 2027 | ¥25,920 | ¥25,920–¥44,280 | ¥49,680 | ¥41,040–¥61,560 | ¥47k / ¥68k |
Exhibit 1: Listed prices at Tokyo Bay Maihama Hotel First Resort by day of week and month (one room, two guests, tax included). Weekday = Monday–Thursday excluding national holidays and nights before holidays (N=83 nights); Saturday = Saturdays excluding national holidays (N=23 nights). Low = the cheapest plan listed for that night; average listed price = the monthly average of each night’s average across all plans. *October covers the 15th–31st only. Source: OTA listed prices (as of October 14, 2026), compiled by the HotelBank Editorial Team
Across the six months, the median weekday low is ¥25,920 and the Saturday low is ¥41,040, so Saturdays cost about 1.6 times as much as weekdays. The average listed price is roughly 1.5 to 2 times the lowest price because the plans vary widely, from breakfast-included rates and larger rooms to packages with park tickets. For two people in a standard room with breakfast, a budget of ¥40,000–¥50,000 on weekdays and ¥60,000–¥89,000 on Saturdays should be close.
National holidays and the New Year period are on par with Saturdays or higher. The lowest price was ¥62,400 for December 31, ¥56,400 for January 1 and ¥52,920 for March 21 (Sunday, Vernal Equinox Day). On the other hand, the lowest price was ¥15,120 for November 3 (Culture Day) and ¥20,520 for January 11 (Coming of Age Day). Even on holidays, the last night of a long weekend can come down to weekday levels.
Where It Sits Among Maihama’s Large Hotels
We compared the median cheapest-plan price at large hotels in the same Maihama area (within about 1 km of the hotel), for the same period and under the same conditions. Each hotel differs in room size, distance from the station and facilities such as pools and restaurants, so read this as a budget guide rather than a ranking.
| Hotel | Rooms | Weekday low (median) | Saturday low (median) |
|---|---|---|---|
| Tokyo Bay Maihama Hotel First Resort | 696 | ¥25,920 | ¥41,040 |
| Sheraton Grande Tokyo Bay Hotel | 1,016 | ¥32,400 | ¥47,160 |
| Hilton Tokyo Bay | 828 | ¥32,617 | ¥50,148 |
| Grand Nikko Tokyo Bay Maihama | 707 | ¥33,000 | ¥50,400 |
| Maihama View Hotel by HULIC | 428 | ¥33,682 | ¥49,222 |
| Hotel Okura Tokyo Bay | 427 | ¥35,530 | ¥47,600 |
Exhibit 2: Lowest listed prices at large hotels in the Maihama area (one room, two guests, tax included). Stay dates October 15, 2026 – March 31, 2027; weekdays N=81–83 nights, Saturdays N=23 nights (same definitions as Exhibit 1). Room counts are from the HotelBank Editorial Team’s hotel database.

Of these six hotels, First Resort has the most affordable cheapest-plan prices on both weekdays and Saturdays. With 696 rooms, it also offers many plans, which makes it easier to match a budget. If being close to the parks or spending time at the hotel matters more to you, each of the nearby hotels has its own strengths, so choose based on the purpose of your trip.
Using It as an Official Hotel
Guests at Tokyo Disney Resort Official Hotels can use the free Disney Resort Cruiser shuttle, which links Bayside Station on the Disney Resort Line with each hotel. Routes between the parks and the hotels are shown on each hotel’s page on the Tokyo Disney Resort official website.
Note that Happy Entry, the perk that lets hotel guests enter the parks early, is for guests of the Disney Hotels. Check the latest terms for Official Hotel perks and services on the Tokyo Disney Resort official website and the hotel’s official website before your stay.
For families with children, breakfast opening times can decide which hotel to book. Early Breakfast for Early Risers (kazokustay, in Japanese) uses official information to compare hotels around Maihama whose breakfast venues open at 6:30 a.m. and have children’s buffet counters.
When to Book: Cheaper Days and Busy Periods
- For the lowest rates, choose a January or February weekday. The median weekday low is ¥23,760 in January and ¥25,920 in February, and the narrow price range makes budgeting easy.
- Saturdays cost about 1.6 times as much as weekdays. The median low for Sunday nights (followed by a weekday) was ¥25,920 (N=20 nights), the same as weekdays. If you are staying one night over a weekend, Sunday is the better choice.
- November Saturdays and the March spring break are pricier. The median Saturday low was ¥49,680 in both November and March, the highest of the six months.
- Book early for the New Year period. From December 29 to January 2, even the cheapest plans cost ¥40,000–¥60,000+.
- Upcoming weekends are already selling out. As of October 14, every listed plan was sold out for October 16 (Fri) to 18 (Sun). For long weekends and regular weekends, booking more than a month ahead is the safe option.
Listed prices change daily. The figures here are listed prices as of October 14, 2026 (one room, two guests, tax included) and are not a guarantee of the rate at the time of booking.

Methodology and Sources
■ Data sources
Listed prices and review scores were compiled by the HotelBank Editorial Team from public OTA data (retrieved October 14, 2026). The history of the name change, room counts by wing and building size come from the operator’s 2019 announcement and company profile (checked October 2026). Access information and the Official Hotel designation come from the hotel guide on the Tokyo Disney Resort official website. Room counts for nearby hotels come from the HotelBank Editorial Team’s hotel database, except Hilton Tokyo Bay, which comes from Hilton’s company profile.
■ Calculation assumptions
Prices are for one room, two guests, tax included. For each stay date from October 15, 2026 to March 31, 2027 (168 nights), we took the single cheapest plan, split the nights into weekdays (Monday–Thursday excluding national holidays, nights before holidays and the New Year period of December 28 – January 3; N=83 nights) and Saturdays (excluding national holidays; N=23 nights), and calculated the median and range by month and for the full six months. The average listed price is the monthly average of each night’s average across all plans. Sunday nights are Sundays followed by a weekday (N=20 nights).
■ Limitations
Listed prices are as displayed at the time of retrieval and do not guarantee the amount paid at booking. Nights that were sold out at retrieval (such as October 16–18, 2026) include the last price listed. Single-occupancy rates are priced separately; halving the figures in the tables does not give the single-occupancy rate. Comparisons with nearby hotels are not adjusted for differences in room size or facilities and are shown as a budget guide. The current status of Sunroute membership benefits could not be confirmed from official sources.
