Otonokizaka High School

Otonokizaka High School, also known as National Otonokizaka High School/Academy (国立音ノ木坂学院), is a high school located in Japan. This is the school where the idol group, μ's, went to before all the members graduated.

Description
Otonokizaka is a school located between Tokyo's Akihabara, Kanda, and Jinbouchou neighborhoods. A traditional school with a long history dating back to 1896, it used to be the top school in the neighborhood with an eminent name, so well-known that even other prefectures were aware of it.

However, it has not adapted well to the changes of time, and gradually lost its students to emerging private schools in the area. Coupled with the falling birth rates, the student population decreased to the point where rumors spread that the school was facing risk of abolishment. The rumors only further fueled the decrease of students, which led to the decision that the school would be closed within three years. The efforts of the idol group, μ's, prevented this from happening. The school is currently headed by Director Minami.

The school possesses an auditorium, a gym, a running track, an archery dojo, and even a stable where alpacas are tamed. From the anime, it is known that the Student Council room is on the second floor overlooking the entrance to the school, while the Idol Research Clubroom is on the first floor. The rooftop is often used by μ's for practice.

The school is described as having no unique points, only an aging school building with ancient facilities.

Uniforms
The school's uniform design remains unchanged from its distant past, consisting of a dark blue blazer worn over a pale yellow sweater vest on top of a white collared shirt. The uniform is completed with black knee-high socks, brown loafers, a pleated blue striped skirt. One can tell a student’s grade by their ribbon. The first years wear blue ribbons, while the second years wear reddish maroon ribbons, and the third years wear greenish turquoise ribbons. The students appear to be free to customize their uniforms as we see with Hanayo wearing black tights, as well as Nozomi wearing thigh-high socks instead of the knee-highs, and Nico wearing a pink cardigan and Maki wearing a gray vest as opposed to the yellow one.

The summer uniform is a short sleeved white shirt with the students wearing the yellow vest over it.

Trivia

 * Based on the hint given by the Love Live! producer, Otonokizaka High School was likely modelled after Seikei University.
 * The hint translates as "The alma mater of someone who was Prime Minister just a while before". Seikei University was the alma mater of Shinzō Abe, who was Prime Minister both before and shortly after the first PV was made.
 * In the manga adaptation, Otonokizaka High School has an affiliated middle school which Honoka, Umi, Kotori, Hanayo and Rin attended. There are no details of such in the anime.
 * Prior to Sunshine!! and joining Aqours, Riko Sakurauchi was a first year student of Otonokizaka due to her old uniform.
 * In Gundam Build Fighters Try there is an off-screen team called "Love Live!" from the "Otonokizaka Academy" (韻木坂学院), being this the first animated cameo between the Gundam and Love Live! franchises.
