原稿 - 日本語 - Kakusenu iradchi to Tachitsukusu ...

this isn t finnish :s maybe japanese..

For sure it is not Finnish. I think it's Japanese.

Thanks tarinoidenkertoja and Freya, I edited with the Japanese flag, as I also think it is Japanese.

please write down the correct Japanese ,and maybe I can help you,I think there is something wrong with your Japanese,for example,"iradchi ",it's wrong.

I don't know whether you mean this "各せぬ 伊ラッチ と 質すくす 自分を 光迷い 悩み 長ら 悔み 長ら 決めらば いいさ。"?

隠せぬ　いらだちと　立ちつくす　自分を　見つ　迷いながら　悩みながら　悔やみながら　決めれば　いいさ。

maybe…　iradchi　→ iradachi
nagra 　→ nagara
　　　　kimeraba →　 kimereba

Well, I thought this is some sort of quote from lyrics of some song.
And This lyric is kind of geeky and Japanese.

Now, its easy to deduce , this is an anime song.

I searched the 隠せぬ苛立ちと 立ち尽くす自分 and found entire lyric in japanese as follwin:

隠せぬ苛立ちと 立ち尽くす自分 を 見つめ 迷いながら 悩みながら 悔やみながら 決めればいいさ

It is anime song from Xenogias or something.
