Yes, they happened in Japan.

XBlaze (year 2050) characters have their names written in kanji, with last name first. BE (year ~2080) characters have their last names written in kanji, while their first names are written in katakana, with last name first.

It is also worth noting that Japanese use katakana to write foreign names, which supports the theory that whatever language they speak in BlazBlue, it's not Japanese.
