Is there an anime?

No, there isn't according to wikipedias site. Thr tác giả has also đã đưa ý kiến that he was not planning to make it a anime either, Yotsubato isn't that type of manga that would look good on anime, it would lind of ruin the atmosphere. :<

Thats at least what the tác giả think, but i think it would be cute as a anime.
