Ikimono Gakari Romanji: How do you write it?

Personally, I like to separate it out with a space, but how do you do it?

If I could read and write kana, I would just do that, but it's not really an option most of the time.

Going by Google search results, the most popular version is no space.

339,000 for ikimonogakari
334,000 for ikimono-gakari
223,000 for ikimono gakari

Wikipedia uses a hyphen and capitalizes the first letter: Ikimono-gakari

P.S. I think this has been mentioned before, but this forum is in the article (thanks to "Kiyoe Chan").

An image on their official website has it with a hyphen, but all lowercase.

I'm pretty sure I've seen it written on CDs with the hyphen too, but I'm too lazy to check right now.

im not sure about that myself... n i've been wondering bout the same question too... but i personally like to refer as Ikimonogakari...

not really knowledgeable bout japanese writings ...but most often "ikimonogakari" is the one that always gives a result in every search...but i prefer to use "ikimono gakari"

"Ikimonogakari" is better for me,,
and "Ikimonogakari" also used at cdjapan,

but at sakura saku machi monogatari cover,,
it's like this
"ikimono
gakari"

also when u searching "ikimonogakari" at google,,
Did you mean: ikimono gakari at the top page will show up...

so maybe ikimono gakari is the right one,,,
