Danchi Tomoo

Danchi Tomoo is based on a manga of the same name by Tobira Oda. The publication began in 2004 on Big Comic Spirits and is still ongoing.
Tomoo is a kid living in a complex apartment with his mother and big sister. His father is always away because of work. MyAnimeList tells you that Danchi Tomoo is a comedy. And it is a comedy, but what makes the anime and the manga really interesting and great are the bittersweet moments. Danchi Tomoo is filled with them.

It's a show about childhood and one can't avoid to feel nostalgic. The jokes are funny but takes you back, ... so there is always a few memories pressing your heart when you are laughing. Japanese childhood is very much alike childhood in many other places, after all.

Tomoo is the average kid with a good heart. He is not good in sports and his grades are not the best, but he is so spontaneous and his emotions come out so easily (specially about his father) that you can't avoid rooting for him and hope he will grow up to be a happy and fulfilled adult someday.
