Uranohoshi Girls' High School

Uranohoshi Girls' High School, also known as Uranohoshi Girls' Academy (浦の星女学院), was a Catholic high school located in Japan. This was the school where the idol group, Aqours, went to. Just like Otonokizaka High School, it has been determined to be closed down. At the end of the series, the school officially closed.

Description
Uranohoshi was a school located near Shizuoka Prefecture, Numazu City, in a small seaside town named Uchiura. It is located at the tip of a cape, surrounded by fields of orange plantations. There were less than 100 students studying in the school. The school was headed by Mari Ohara who is also a third-year student (now graduated).

Uniform
The school's summer uniform was designed after a classic white sailor uniform, with a gray collar over a white shirt, and a gray skirt. The rims of the collar, sleeves and shirt are patterned with a double white line running across them. In winter, a long-sleeved cream-colored sweater is added over the shirt. Similar to Otonokizaka, the students appear to be free to customize their uniforms as we see Hanamaru wear a yellow cardigan and black tights, as well as Yohane wearing thigh high socks instead of the knee-highs, and Mari wearing white thigh high socks with small pastel blue bows, this also says that in the summer school uniform, she wore the usual uniform with a bluish green vest, and white knee-highs instead of black.

The students wear ties to differentiate their years, with the first years wearing orange, the second years wearing red, and the third years wearing teal. During winter, the first and second years wear ribbons instead, while the third years continue wearing ties.

During the transition period when they change from summer to winter uniforms (November-December), the school briefly switches to a black sailor uniform with a triple white line along the rims of the collar and sleeves. The years are not differentiated in this uniform, with everyone wearing the same white tie. This uniform was the old winter uniform for Uranohoshi Girls' before the new one was designed to better combat the cold weather, and is retained out of a sense of legacy.

Trivia

 * Based on the Kimi no Kokoro wa Kagayaiteru kai? PV, the exterior of the school is likely modeled after Nagaisaki Junior High School. The exterior of the school and its pool as shown in the PV can be seen here.
