Are surnames only written with kanji?


I wondered about this. I know the first name can be written in Hiragana,
Katakata, Kanji (and maybe a mix of it?) but how is it with family names? I
think I've never seen one which was mixed, Hiragana or Katakana unless it was
a stage or foreign name. Do surnames not only with Kanji exist?




Quite a few **_family names_** contain kana in them. There is no law
restricting the use of kana in family names, either.

I have personally met people with family names like:

[一ノ瀬]{いちのせ}、[二ノ宮]{にのみや}、[一ツ松]{ひとつまつ}、[藤ヶ崎]{ふじがさき}, [城ケ崎]{じょうがさき}, etc.

A quick search on the internet will give you these as well:
