Tokyo DisneySea occupies more ground than Tokyo Disneyland and offers fewer things to do on it. The operator’s own fact book gives the theme park area of DisneySea as 610,000 square metres against Disneyland’s 510,000, and in the same table counts 39 attractions and entertainment facilities at DisneySea against 43 at Disneyland for the financial year ended 31 March 2026.
Both figures come from Oriental Land Co., Ltd., the company that operates the Disney-branded facilities at the resort under licence from Disney Enterprises, Inc. The numbers below are taken from that fact book, from the company’s own corporate history, and from the park page as it stood on 15 October 2026. Where a figure is a subtraction or a division of two published values, this article says so.
The fact book puts 100,000 square metres between the two parks
The row is labelled area of the theme park, not total site area, and that distinction matters because the resort contains hotels, a shopping complex and a monorail that sit outside both parks. On that measure DisneySea is the larger of the two by 100,000 square metres, which is my subtraction of the two printed figures.
The company does not publish a figure for the whole resort on the pages read here, so this article does not give one. The area row read here gives a single figure for each park and is not broken down by themed port, so the published total cannot be divided between them.
DisneySea has eight themed ports, and the operator’s page does not name them
Oriental Land’s park profile states that DisneySea features eight distinct themed ports, and describes the park as themed to the myths and legends of the sea. The same page describes Tokyo Disneyland as composed of seven areas. The difference between the two counts is one, by my subtraction.
What the profile page does not do is list the eight ports by name. A reader arriving at that page looking for the names will not find them there, and this article does not supply a list from elsewhere. The page does state one thing about the park’s edge that is easy to misread as marketing: the Tokyo DisneySea Hotel MiraCosta stands at the park entrance and is, in the company’s words, actually inside the park.
| Item as the fact book labels it | Tokyo Disneyland | Tokyo DisneySea |
|---|---|---|
| Area of the theme park | 510,000 square metres | 610,000 square metres |
| Opening date | 15 April 1983 | 4 September 2001 |
| Attractions and entertainment facilities, year ended 31 March 2026 | 43 | 39 |
| Themed areas or ports, per the park profile page | 7 areas | 8 ports |
The two opening dates are 18 years, 4 months and 20 days apart
The fact book prints both opening dates directly: Tokyo Disneyland opened on 15 April 1983 and Tokyo DisneySea on 4 September 2001. Counting forward from the first date to the second gives 18 years, 4 months and 20 days, and that interval is my calculation rather than a figure the company prints.
The company history puts three 2001 openings together: Tokyo DisneySea, the Disney Resort Line monorail and the Tokyo DisneySea Hotel MiraCosta all entered service that year. Tokyo Disneyland had been running for 18 years by then, by my subtraction of the two opening years, and the Tokyo Disneyland Hotel is listed as opening in 2008.
The ground under both parks was finished 8 years before Disneyland opened
Oriental Land’s corporate history starts well before either park. The company was established in 1960. In 1962 it concluded the Urayasu District Land Reclamation Agreement with Chiba Prefecture. Reclamation work commenced in 1964 and the history records it as completed in 1975. The agreement with Walt Disney Productions concerning the operation of Tokyo Disneyland came in 1979, four years after the land was finished.
So the sequence runs land first, licence second. The reclamation was complete 8 years before Tokyo Disneyland opened and 26 years before Tokyo DisneySea opened, both of which are my subtractions from the years in the company’s history. The resort stands in Urayasu, in Chiba Prefecture rather than in Tokyo, which places it in a prefecture whose own geography is covered in Chiba is larger than Tokyo and Kanagawa combined.
Fantasy Springs opened 23 years into the park’s life, in the same year as its hotel
The corporate history lists Fantasy Springs and the Tokyo DisneySea Fantasy Springs Hotel as both opening in 2024. Measured from the park’s 2001 opening that is 23 years, by my subtraction of the two years in the history. The history gives the year only and not a day or month for either, so this article does not print one.
The same list is where the resort’s hotels can be counted. The company’s resort section lists six: the Disney Ambassador Hotel, the Tokyo DisneySea Hotel MiraCosta, the Tokyo Disneyland Hotel, the Tokyo Disney Celebration Hotel, the Tokyo Disney Resort Toy Story Hotel and the Tokyo DisneySea Fantasy Springs Hotel. Their listed opening years are 2000, 2001, 2008, 2016, 2022 and 2024.
| Year in the company history | Event as the history records it |
|---|---|
| 1960 | Oriental Land Co., Ltd. established |
| 1962 | Urayasu District Land Reclamation Agreement concluded with Chiba Prefecture |
| 1964 | Reclamation work commenced, recorded as completed in 1975 |
| 1979 | Agreement with Walt Disney Productions concerning Tokyo Disneyland operation |
| 1983 | Tokyo Disneyland opened |
| 2001 | Disney Resort Line, Tokyo DisneySea and Tokyo DisneySea Hotel MiraCosta opened |
| 2024 | Fantasy Springs and Tokyo DisneySea Fantasy Springs Hotel opened |
Overseas guests were 15.1 per cent of the parks’ visitors in the year to March 2026
The fact book reports overseas guests for the year ended March 2026 as 416, in units of ten thousand people, which is 4,160,000. Alongside it the book gives an overseas guest ratio of 15.1 per cent for the same year.
Dividing the first figure by the second implies a combined attendance of roughly 27.5 million for the year. That division is mine, and it carries the rounding of the published figures: the guest count is printed in units of ten thousand and the ratio to one decimal place, so the implied total should be read as an approximation rather than as a published number. The fact book reports both of these figures for the two parks together and does not split them between DisneySea and Disneyland, so neither the 4,160,000 nor the 15.1 per cent can be attributed to DisneySea alone.
The park page printed one day’s hours and four dated event windows
Operating hours are published per day rather than as a standing schedule. Read on 15 October 2026, the DisneySea page gave that day’s hours as 9:00 a.m. to 9:00 p.m. and showed tickets as available. A reader planning a different date needs to read the page again for that date.
Four dated event windows were listed on the same page. An event called Sparkling Jubilee runs from 15 April 2026 through 31 March 2027. Disney Halloween runs from 16 September through 31 October 2026. Lazos de la Familia runs from 16 September through 2 November 2026. Disney Christmas runs from 11 November through 25 December 2026. The first three were marked as in session on the date read.
The costume guidance on that page is a notice headed “Wearing Costumes During Disney Halloween” and dated 15 September through 31 October 2026. The only restriction it states is narrower: for 1 October through 15 October 2026, guests are asked not to wear costumes when visiting the parks. The notice prints no rule for the rest of its own window.
The resort outside the two parks is counted separately
Three figures on the profile page describe the parts of the resort that need no park ticket. Ikspiari, the shopping and dining complex, is described as composed of 140 shops and restaurants together with a 16-screen cinema complex. The MAIHAMA Amphitheater is given a seating area of 2,170 seats surrounding the stage. The Disney Resort Line is described as a monorail system running within the resort, with no figure for its length, its station count or its fares on the pages read here.
One ticket admits the holder to one park
The two parks are priced and admitted separately, and the park page carries no price figures at all: it links to a ticket search instead, which is consistent with admission being sold at prices that move by date. For that reason this article prints no ticket price. How the single-park rule works in practice, and what it means for a visitor trying to see both, is set out in Tokyo Disneyland and DisneySea tickets each admit the holder to one park.
What the figures above add up to is a park that covers more ground than its older neighbour while listing fewer things on it: 100,000 square metres more area, four fewer attractions and entertainment facilities, one more themed area, and 23 years between its opening and its newest port. The ground it stands on was reclaimed before the licence to build on it was signed.
