When you want something, sometimes you just have to go ahead and take it.

On his formidable debut album, ¡°Passport & Garcon,¡± South Korea-born rapper Moment Joon lays claim to his present home in suburban Osaka with unusual specificity. When he reps his eponymous neighborhood on the track ¡°Iguchidou,¡± he even gives his apartment number, telling listeners: ¡°If you¡¯ve got a problem with me, come and talk.¡±

The invitation ¡ª delivered, like nearly all his lyrics, in Japanese ¡ª is sincere. But there¡¯s also a sense of a spot being staked out. It¡¯s a declaration that the self-styled ¡°immigrant rapper,¡± real name Kim Beom Joon, isn¡¯t going anywhere.
