Japanese Text in game overviews

Is putting Japanese text in game information entries frowned upon or can it be added in brackets next to the english meaning on titles originally in Japanese?

For example in Katamari Damacy Tribute game entry in the soundtrack section I initially wrote several of the artists and songs in the original Japanese e.g.
大橋卓弥 (from スキマスイッチ)  -  塊オンザウィングス

before realising that for a lot of people (without Vista that is) the entry would come up as  a bunch of question marks and even if not wouldn't be able to read it anyway and I translated it to
Takuya Ohashi (from Sukima Switch)  -  Katamari On the Wings
but didn't put back the original Japanese next to it in case Japanese text isn't allowed.

Some things however don't translate as well, should they just be spelt out in english characters phoenetically only?
On Wikipedia for many games, music and movies, the original title or name of a character, song or artist is listed in brackets. A lot of the time, for reference, a Giant Bomb user may need the original Japanese to hunt down infomation, videos, music etc on particularly obscure or Japan only games.

Thanks

As Jeff once said, Giant Bomb is based in San Francisco, so it's called Indigo Prophecy and not Fahrenheit.

But isn't the internet and the Giant Bomb website for the whole world?

Oh yeah of course, I don't mean overriding the default, just adding information to the text

No Kanji. Please only use Romaji.

Well, there goes 90% of the help that I can give xD
