# Keio University

Keio University (慶應義塾大学, Keiō Gijuku Daigaku), abbreviated as Keio (慶應) or Keidai (慶大), is a private research university located in Minato, Tokyo, Japan. It was originally established as a school for Western studies in 1858 in Edo. It was granted university status in 1920, becoming one of the first private universities in the country.
The university is one of the members of the Top Global University Project (Top Type), funded by the Japanese Ministry of Education, Culture, Sports, Science and Technology. Keio University is also one of the member universities of RU11 and APRU, and it is one of two Japanese universities (alongside the University of Tokyo) to be a member of the World Economic Forum's Global University Leaders Forum.

## Overview

Keio traces its history to 1858 when Fukuzawa Yukichi, who had studied the Western educational system at Brown University in the United States, started to teach Dutch while he was a guest of the Okudaira family. In 1868 he changed the name of the school to Keio Gijuku and devoted his time to education. While Keio's initial identity was that of a private school of Western studies, it expanded and established its first university faculty in 1890.
Keio has approximately 30 Research Centres located on its five main campuses and at other facilities for advanced research in Japan. Keio University Research Institute at SFC (KRIS) has joined the MIT and the French INRIA in hosting the international W3C.
As of June 2022, Keio University holds the largest endowment fund among all Japanese universities, with ¥78 billion. This is followed by Waseda University at ¥29 billion, Kyoto University at ¥20 billion and the University of Tokyo at ¥15 billion.

## History

Keio University (慶應義塾大学, Keiō Gijuku Daigaku) was first established in 1858 as a School of Western studies located in one of the mansion houses at Tsukiji by founder Fukuzawa Yukichi. "Shinshu Kan" was the original name of Keio University. Keio University's root is considered to be the Han school for Kokugaku studies, named Shinshu Kan established in 1796. It later changed its name to "Keio Gijuku" in 1868, which originated from the era name "Keio", with "Gijuku" as the translation of Private school. It moved to its current location in 1871, established a Medical school in 1873, along with the university department of Economics, Law and Literacy studies in 1890.

## Student life
### Societies

In Japanese universities, student societies are known as "circles". There are over 410 circles at Keio University by estimate, including both official and unofficial circles.

### Athletics

The interest of Keio's students in baseball stretches back to the early years of the 20th century. In 1913, an American touring team of players from the New York Giants and the Chicago White Sox played an exhibition game against the Keio team. In a 1932 exhibition game, the Keio team beat the University of Michigan team, which was then touring Japan. Keio's baseball team plays in the Tokyo Big6 Baseball League.

#### Kei-So rivalry

Traditionally, there has been a strong rivalry between Keio and Waseda University. There are annually many matches between the two universities in several sports, such as baseball, rowing, rugby, lacrosse, track and field, American football, association football, aikido, karate, basketball, tennis, swimming, fencing, figure skating, ice hockey, and field hockey. These games are called "Kei–So Sen (慶早戦)" or, more generally, "So–Kei Sen (早慶戦)".
The Kei-So baseball rivalry, which dates back more than a century, is especially famous because of its importance in Japanese baseball history. The most famous Kei-So baseball game, which was played on October 16, 1943, was made into a movie titled "The Last Game – the Final So-Kei Sen -" in 2008.

#### American football
### Scandals

In October 2016, six male students from Keio Advertisement Society, a long-standing student club known for its organisation of the Miss Keio pageant contest, were investigated for gang rape during a club activity. An out-of-court settlement was reached and the students were not prosecuted. In May 2018, another three students were arrested for sexual assaults.
In March 2017, a student tennis club was disbanded after a student died of alcohol poisoning during a club activity. Two other Keio students died due to over-drinking in 2012 and 2013.
In June 2017, the school's election committee unconventionally selected Haseyama Akira, a legal history professor who won second place at the general election among teachers and staff, to be the school's new president, breaking a 50-year convention.
In late 2019, both the American football team and the cheerleading club suspended club activities for "inappropriate behaviours".
In January 2020, it was reported that a former member of the school president's secretarial staff had installed a camera in a female toilet stall on the Mita campus, filming over a thousand videos over 3 months.
