I don't think that's right? Thinking of other solo artists on last.fm, I can't think of a precedent where the first and last name are separated - 椎名林檎, 平沢進, 友川かずき, to give the most listened ones from my library as examples. There is no reason for Ryutaro to be an exception, even his wikipedia page doesn't use a space.

Ah... nevermind, someone took the time to correct me by showing me examples of this spelling used in his social media. Sorry

The official site its with space, channel in youtube with space, twitter official too. The cover from regular edition is with space and 「デも/demo」 this too. Its so obvious to u understand that no space its wrong Tag. Anyway use what u like.
