Later in his life he acquired Japanese citizenship. Due to early influence from his Marxist-Leninist father, he studied at the Chongryon-affiliated elementary school and middle school. Afterwards his father switched his affiliation for Mindan, he instead studied at Hozen High School (保善高等学校) in Tokyo Shibuya. He graduated in Law at Keio University. With the strong confusions with Chongryon, Mindan, and Japanese politics he wanted to promote an alternative "Korean-Japanese" (コリアン・ジャパニーズ) identity to overcome social obstacles, but later he abandoned this concept.
