Suguru Koshigaya (越谷 卓 Koshigaya Suguru?) is one of the main characters of Non Non Biyori series. He is the older brother of Komari Koshigaya and Natsumi Koshigaya, and is the oldest student in their school.



Suguru Koshigaya

Suguru has black hair that has forelocks swept to the left, black eyes, black diamond-shaped glasses and looks more like Yukiko Koshigaya (Suguru's mother) than Komari Koshigaya and Natsumi Koshigaya (Suguru's younger sisters) do.


Suguru is a very quiet and smart person who mostly keeps to himself and doesn't share his thoughts with others. While he doesn't use his voice, he speaks through gestures and facial expressions. He's very talented in art, showing him being able to create a cat sculpture out of clay and being able to play the electric guitar. His artistic talent goes as far as to enable him to bend a wooden plank into the shape of a bowl before securing it with nails. He can run fast and has good grades. He also can spin a pencil really fast to show he is excited.


  • The name Suguru means "table, desk, high" (卓).


  • (Mini-Spoiler Alert): Suguru has a few "almost" speaking and one speaking part throughout the series; Two times he almost spoke to Renge Miyauchi (once when he was chewing grass and the other when they were in a convenience store). But, in both cases, Renge was surprised by the sight of him and ran off before he could say anything. The time he actually spoke was when he was speaking to Natsumi Koshigaya when she came to his room; we can't hear him, however, as he is jamming out loudly on his electric guitar. When Natsumi finally gets him to stop playing so she could hear what he was saying, they are interrupted by a boisterous Konomi Fujimiya busting through the front door yelling, "Konnichiwa!!"
  • Suguru was hit with two small fish and a larger fish.
  • Suguru is 171cm tall.
  • In the manga, Suguru is given many bizarre and hard to believe attributes, such as "has a secret super power to always win Sailor Moon show tickets".
