Exploring all the quirks of this anime never ceases to amaze me. You see commenting on Kurenai Sanshiro is like opening a Matryoshka, a Russian doll, every time you uncap a doll you find a smaller doll inside it and so on. Likewise for Kurenai Sanshiro, aka Judo Boy, each info leads to another and so on.

So this is no brief review but I humbly believe the anime deserves these clarifications.

First of all Kurenai Sanshiro was never licensed in USA, this might explain why English reviews about it are so scarce. However the anime aired in foreign countries under the name ...
