Since July 2021, it is operated by PT Taman Wisata Candi Borobudur, Prambanan, dan Ratu Boko, a subsidiary of the state-owned tourism holding company Injourney.

The park is a synopsis of Indonesian culture, with virtually all aspects of daily life in Indonesia's 26 (in 1975) provinces encapsulated in separate pavilions with the collections of rumah adat as the example of Indonesian vernacular architecture, clothing, dances and traditions are all depicted impeccably.

Apart from that, there is a lake with a miniature of the archipelago in the middle of it, cable cars, museums, Keong Emas IMAX cinema (Indonesia's only IMAX cinema until the 2010s), a theater called the Theatre of My Homeland (Theater Tanah Airku) and other recreational facilities which make TMII one of the most popular tourist destinations in the city.

[3] The idea of presenting Indonesia on a small scale was conceived by first lady, Siti Hartinah, better known as Tien Suharto.

The concept of this culture-based recreational area was inspired by Indonesia's unparalleled natural riches and local folk diversity.

[4] In January 2022, the revitalization of TMII was started to support the side event of the 2022 G20 Bali summit in Jakarta, with its new concept named "Indonesia Opera", designed by Urban+.

[8] Apart from that, visitors are no longer allowed to explore the complex using personal cars or motorcycles, because the park is designated as a low-emission zone.

The team claimed the advantage of utilizing this uneven terrain was the ability to create interesting and diverse landscapes and enclosures, as well as reflecting the various characteristics of the Indonesian environment.

[2] TMII currently has 33 pavilions of the provinces of Indonesia, 7 places of worship, 24 parks/open spaces, 17 museums, and 18 amusement rides and other facilities.

TMII attempted not only to reconstruct the homes, but also to create a realistic model of the environment and shelters of the various people of Indonesia.

Since 1975 until the 2000s, the original design of TMII consisted of a model of the traditional houses (rumah adat) from the 27 provinces of Indonesia, including East Timor.

Since Indonesia consists of 33 provinces (in 2004), the new province pavilions of Bangka Belitung, Banten, West Sulawesi, North Maluku, Gorontalo, Riau Islands, and West Papua have been built in northeast part of the park, although the size and area of these pavilions is much smaller than the previous ones.

The religious buildings are: There are about ten gardens spread within TMII complex, but most are located primarily on the north and northeast side of the main lake: Taman Burung is divided into five exhibits: Kubah barat (West dome) which include birds from the Greater Sunda Islands (Except Sulawesi) and the Lesser Sunda Islands, kubah timur (East dome) which include birds from Sulawesi, the Maluku Islands, and New Guinea, a free ranging river exhibit, raptor aviaries, and other aviaries and exhibits scattered around the park.

Visitors are diverted to use electric-powered shuttle microbus service called angkutan keliling or angling for free.
