• In only 17 Episodes Hayama has managed to kiss, hug twice and touch the chest of Sana.
  • It took Sana 60 episodes to figure out she loves Hayama...and 6 Manga Volumes. (Well at least her density level isn't as high as Sakura...that girl it took 70 episodes and a movie!)
  • In the anime Sana and Naozumi actually go out in the NY episodes, contrast to the manga where Nao refuses to go out with her when he realizes she's sick.
  • Hayama has gotten jealous of Naozumi on more than one occasion…
  • Hayama has only kissed Sana 3 times in the entire series of Kodocha
  • Hayama and Fuka never kissed  at all. Neither did Sana and Naozumi.
  • In season 2 of Kodocha (ep. 50--102) Hayama will call Sana by her first name instead of "Kurata" like he did in season 1.
  • Naozumi blows long objects (horn, that thing you scoop up soup with..) to relieve stress...hmm…
  • Miho Obana shows up in almost every Kodocha episode….
  • A band member Mamo-chan from Tokio (the guys who did the first season OP 7 O'Clock news) shows up in the first episode of Kodocha.
  • In the Kodocha manga...there aren't any Babbits….but if you look one shows up in Vol. 6, and the other shows up on the cover of Volume 10.
  • Babbit has a lot of relatives…from various parts of the world!
  • I have never seen Sana be serious for more than 5 minutes except the time when she found out Hayama is dating Fuka.
  • In the last few eps of Kodocha….for some reason it corresponds to the end of Vol. 7 and the beginning of Vol. 8 of the manga.
  • In episode 102 at the end where all the parodies are….Rei finds a newspaper with an article on Asako getting married to the director of Mizu no Yakata.
  • In season 1, Zenjiro mentions more than once how much he hates this anime. ^_^;
  • In the Kodocha OVA, Sana's voice is played by the same Seiyuu as Sasami from Tenchi Muyo. Hayama's voice is played by the seiyuu who did Shinji from Evangelion, Haruka from Sailormoon, and Yukito from Card Captor Sakura.
  • In the Kodocha OVA Sana is overly developed for a 6th grader...and has blonde hair.
  • In the Kodocha OVA Mamma has 2 guys asking her for her essay instead of Onda from the TV series.
  • There have been more than 1 rumor of Sana & Naozumi...and yet people believed in every one of them...even Hayama.
  • In the NY episodes there's a guy named Brad who looks like Hayama with lighter hair, and he supposedly dates Naozumi's half sister Lucille. (Hen..)
  • In the Kodocha manga, Hayama and Sana almost have sex... ^o^;
  • They never do because Sana is ticklish and kept laughing…^^;;
  • Contrast to the manga, in the Anime SANA is the one who goes to America, NY...in the manga Hayama goes to NY to get surgery done on his lifeless arm. (Kawaiisou V_V)
  • There are 2 specials in each season of Kodocha, and in each one everyone portrays an animal or a weird object. In the first special everyone is a moth and then a caveman. In the season 2 special Sana is skunk, Fuuka is goat, Aya is an elephant, Tsuyoshi is a fish and Hayama is a buuta(a pig! ^_^)
