Hi there. Quick question. Do japanese email addresses use the latin alphabet and numerals, or do they have hiragana, katakana, romaji, etc.?

There’s an international standard, so there is some unified set of characters that anyone can use no matter where they are. If they can, technically so can you.
I know that characters beyond the standard English alphabet are technically possible, but whether that extends to kana and kanji, I have no idea.
Though if you get your email through a provider, the provider might limit your options more than the standard does.
In practice, I’ve never seen a Japanese email address that didn’t have the same kinds of characters we use.
Romaji is usually just latin characters, btw… In most cases. Yes, some systems have special characters, but they’re not necessary for all romanization systems.
Whoops that was a typo. I meant kanji, not romaji.
Yeah, I was reading about how there is now an international standard that allows for non-latin characters in email addresses now as well as any Unicode, so even emoji can be used, but… most email services don’t support that yet. Wasn’t sure if Japan was ahead of the curve or something and already widely using email addresses with Japanese characters rather than latin text. Looks like the answer is not yet.
Thanks.
Yeah it seems like RFC 6532 allows international characters, but I think you’d be hard pressed to find a provider that allows it and I’ll bet more than a few sites would break with a non-ascii email

I didn’t know I wanted to know about this topic, but I secretly did. I guess it does make sense to still stick to the same ASCII-character set of the past standard.
In that sense, it’s like web addresses. Now you can make us of ö ä å, but I still can’t remember having seen a web address using them. Basically, most cities in Sweden already have domains by know, without them.
So the standard hasn’t really changed, even if the technological solution exists now.
Domain names are a bit different since the special characters are encoded in the URL using the xn-- prefix and the code of the character. Those addresses usually don’t look great so the main use of the URLs with the special characters is to redirect to the ‘clean’ version of the URL.

I see. I always thought they were similar. Thanks for clearing that up! ^>^
