Teitan Elementary School
Teitan Elementary School is a coeducational school serving grades 1-5. It is affiliated with Teitan Middle School, Teitan High School, and Teitan University. Teitan Elementary School has been around for a long time, but the timeline is somewhat conflicted as to when it began. Agasa attended Teitan elementary which means it is as least 40 years old; however, the first graduating class based on Sumiko Kobayashi's history is 33-34 years ago. According to the anime, the new school building was constructed 30 years ago. Unlike Teitan High, Teitan Elementary does not currently require a uniform. However, it is worth noting that, in the anime, Shinichi referred to the classic "blue jacket over a white shirt with a red bowtie" outfit he first wore as Conan as his old primary school uniform, implying Teitan Elementary at one point did require uniforms.
 Layout and facilities
The main building containing the classrooms is arranged in a rough upside-down U shape. Additional facilities for students are located in the back of the building. Students pass through the front gate and walk across the main quad to reach the shoe lockers.
