I know. Japense characters, like Ash または Edward from Full Metal Alchemist have insane years of age.Ash will forever remain 10(sue me if I'm wrong), but Edward, on the other hand, is growing. Not physically(he'd flip if he hears me say that), but in age. He was 12 when he became a state Alchesist, stayed 15 for the entire series, the shot up to 18 in the movie. Proof:" What, あなた thought I'd still be a runt when I'm 18 years old?!?"Lol. Saw the entire thing, plus the movie,from beginning to end.
Technically, he should be above drinking age によって now. If he was 10 at the beginning of the first season, and there are now 14 seasons. But if あなた count each journey around each region as one year, he should be at least 15 または 16 years old. No matter how あなた look at it, it doesn't make sense that he would still be 10.
For some reason, yes they do state that he is supposedly still ten years old even though he's been the same age since he first started out in the Kanto region. My answer as to why this is that it's silly! Ash was 10 in season 1. Now, about 15 seasons later, he's still 10?(If it's like that, then why did his voice deepen?) To answer the question, I think it's bcuz the producers want to keep Ash young in order for the new generation of Pokemon watchers to feel the same way that the first generation of Pokemon watchers felt. Its kind of like they're reinventing Ash for the new audiences, but keeping his original age for the sake of the viewers I suppose. Hope I helped! :)
U R right but in カートゥーン characters don't grow normally (even though in the battle frontier before ash's last battle with brandon ash told pikachu, charizard, squirttle and bulbasour that quote:"a lot has changed over the years.").
