Seeing as we’re all pretty much required to wear bicycle helmets here in Japan after the introduction of the new cycling helmet rules here this month, I figured I’d start to pull apart (and curate for now) some of the best advice regarding choosing a good helmet here in Japan, including the best bike helmets list for kids.

A lifelong cyclist myself, and triathlon official, I certainly know the importance of a helmet. Plus, I major fall when I was a kid head first over the handlebars (with a helmet on, thankfully!) cemented my belief in their importance for safety. And, heck… they can kinda look pretty darn cool… even when people make fun of you—like they did when I was in college. Now everyone wears one without even giving it a second though. Time for us here in Japan to pick up the pace a bit, no?

This is a beginning guide, and I’ll flesh it out over the coming weeks. Enjoy for now! Cheers, Doc
