Gaming Mystery gift via code trouble

I was trying to get a mystery gift via code with a jpn X and a us 3ds Running homebrew channel's region free launcher and I get a message somewhat like this.

この ツリアルコードの おくうものほ

You need to redeem the code on a Japanese system, the game's region doesn't matter.
