Dopperugengâ (2003) by Kiyoshi Kurosawa
aka: Doppelgänger

There he is. Suddenly and without any warning nor invitation. He is unwanted, obtrusively annoying and makes no attempts at all to leave. Far from it! He decided to come, and with you he is going to stay. He belongs to you, and you belong to him. He is your exact double from the outside, but the executive devil of your innerst thoughts and your suppressed will. He’s come to help you. Open yourself and let him in!
