Barakamon was a manga that was recommended when I was looking for stuff similar to Yotsuba&, and is likely the manga I've most enjoyed reading so far. It follows the MC who is working towards becoming a calligrapher, following in the footsteps of his famous father. After a failed show, Handa Seishu moves to a remote island to attempt to seclude himself in his studies. There, Handa begins to open up to the community around him, and his experiences bleed into his work, bringing more life and flavor to his work as a calligrapher. The easiest manga for me to recommend to anyone. Story and castare both fantastic, it does a great job of staying funny while instilling the lessons it wants to teach both the characters and the readers, and has a lovely light-hearted tone throughout the entire manga.
