How old toshiro and is there a episode when it's his b-day?If here is can u plz tell me.

Toshiro maybe about 90 or 80 years old even tho he looks maybe 12.
In the show when they went back 100 years he wasnt there.

Toshiro-chan may look like Karin's age but he's like 13 or 14 years old.

I'm not sure if this is the right answer but I'm going to guess and say he is 13 years old. but if I'm wrong you can look it up at absolute anime.com

I looked on google and it says its indeterminate.No one knows,but i found a website that said hes 10-13 in his physical age.

Toshiro is about 90 but appears about 12, his birthday is December 20th. I can't remember an episode of his birthday, but I think I remember a Shinigami Cup where Ukitake got the 12th squad to make a lifesize sculpture of Toshiro for Toshiro's birthday...
