## Background[[edit](/wiki/index.php?title=Ryujiro_Uematsu&action=edit&section=1 "Edit section: Background")]
Ryujiro Uematsu is the current principal of [Teitan Elementary School](/wiki/Teitan_Elementary_School "Teitan Elementary School"), which [Conan](/wiki/Conan_Edogawa "Conan Edogawa"), [Haibara](/wiki/Ai_Haibara "Ai Haibara"), and the [Detective Boys](/wiki/Detective_Boys "Detective Boys") attend. He has been serving with the school for at least thirty years, ever since the new school building was constructed. He softly admonishes [Genta](/wiki/Genta_Kojima "Genta Kojima") for committing abuse on the schoolhouse, when the latter vented his frustration about the strange night-time occurrences for the last few weeks. Some of these were actually committed by the vice-principal, after he had lost hairpiece when it got lost to a gust of wind in the teaching staff room. Uematsu had found and hid it.
## Personality[[edit](/wiki/index.php?title=Ryujiro_Uematsu&action=edit&section=2 "Edit section: Personality")]
He is a kind and also serious man. He has strong principles to show the school buildings respect, but he also has a mischieving side, showed when he hid his vice-principal's lost wig, so the poor man couldn't find it. He is a very easy-going and supportive person, who tries to encourage both his teaching staff and his student charges into following the right path. However, he is also a rather shrewd and eccentric person, as he likes to play jokes whenever the opportunity presents itself, especially on overly shy people. Part of this eccentricity is expressed by his notably overlong eyebrows, which droop down from the side of his temples.

## Different looks[[edit](/wiki/index.php?title=Ryujiro_Uematsu&action=edit&section=11 "Edit section: Different looks")]
* His looks don't change a lot between episode 112 and episode 606, although he becomes a bit more detailed and arranged. In episode 889, there is a major change that was done in his appearance, making him look younger and his hair paler. His eyelashes are a bit shortened and are less expressive. He is now also able to open one eye when he is talking, and only when he is serious and his creepy look compared to before, when his eyes were always shown closed.
* However, his look changed back to old one in episode 1170, as the animator in charge of his scenes didn't have access to the new one for references.
