Sejong University (SJU; Korean: 세종대학교; Hanja: 世宗大學校; RR: Sejong Daehakgyo) is a private research university located in Seoul, South Korea, known for its standing in hospitality and tourism management, dancing, animation and rhythmic gymnastics.

Founded as the Kyung Sung Humanities Institute, it was renamed in 1978 to its present name in honor of Sejong the Great, the fourth king of the Joseon Dynasty and overseer of the creation of the Korean alphabet Hangul.

Over the years, the university expanded its academic programs and facilities, including the establishment of its main building in 1987 and the Sejong Museum in 1973.

The history of Sejong University began in May 1940 when the Kyung Sung Humanities Institute was founded by Dr. Youngha Choo and Dr. Okja Choi.

[3] In 1999, three new graduate schools were added: Software Engineering, Science and Technology, and Performance Art Administration.

In 2004, the Ministry of Education & Human Resources Development recognized Sejong University for excellence in promoting originality, innovation, and academic achievement.

Sejong University also houses the Daeyang Humanity College, a center dedicated to the core principles of liberal arts education.

The Yokohama 3+1 International Program allows students to study for a year in Japan, enhancing their proficiency in Japanese literature and culture.

In 2007, the October issue of Molecular Cell published the groundbreaking article by Dr. Soo-Jong Um and his research team entitled, “Active Regulator of SIRT1 Cooperates with SIRT1 and Facilitates Suppression of p53 Activity.” The article describes a nuclear protein and active regulator SIRT1 (AROS).

[40] The university will receive a funding of 10 billion won from the government to develop and train resource specialists.

[41] In October 2010, Sejong University signed an MOU with Syngenta AG, a leading global Swiss agribusiness company, to develop new innovative breeds and research talents.

The campus also includes the Sejong Elementary School building, Gwanggaeto-gwan, the Student Center, and the Athletics Field.

It also includes essential academic facilities like lecture halls, research laboratories, and the Dongcheon-gwan (University Library), which serves as a central resource hub.

[48] In addition to these academic and functional spaces, the campus provides various student amenities such as cafeterias, gyms, and open areas.

Green spaces, including gardens and walking paths, are integrated throughout the campus, offering students areas for relaxation.

The proximity of Sejong University to Seoul Children’s Grand Park provides additional space for leisure and outdoor activities.

Gwanggaeto Hall is a 15-story building above ground with 4 storeys underground, whose construction started on July 2, 2002, and finished on April 25, 2005.

[56] Basement floors host a café, a convenience store, an international language school, and a large convention hall; and on the rooftop is sited a helipad, plus a swimming pool.

Standing on a mild slope, Gwanggaeto Hall has 15th-floor views for a sweeping look out across Lotte World Tower, Jungnangcheon Stream, the Han River, and Yongmasan Mountain.

[57] It is operated by the Seoul Metropolitan Office of Education and is named after King Sejong, reflecting its focus on academic excellence and cultural heritage.

[58] The school offers primary education with a curriculum that includes a range of academic subjects and extracurricular activities.

The official opening ceremony took place on May 5, 1973, with former President Park Chung-hee and the First Lady Yuk Young-soo attending it.

[59] The museum was designed in the unique Baekje pagoda style and contains more than 5,000 relics, ranging from folk art to ceramics, royal court costumes, calligraphy, and paintings.

The collection includes royal regalia, court dresses, personal ornaments, pendants, Korean traditional ink paintings, calligraphies and pottery.

Student facilities include a 2,800-seat multi-purpose performance hall, main athletic field, sports complex, tennis courts, health clinic, restaurants, cafeteria, coffee shops, bank, post office, bookstore, stationery store, and travel agency.

Dae Dong Je is a university-wide festival held during the fourth week of May every year to celebrate the university's birthday.

The 2023 event, themed Happy Sejong Day, marked the return of in-person festivities after four years.

[64] Highlights included outdoor busking performances by individuals and teams, food trucks offering diverse options, and activity booths organized by external companies and student clubs.

Sejong University student clubs are classified into six categories: Performance, Sports, Service, Culture, Academic, and Religion.
