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 — delivered, like nearly all his lyrics, in Japanese — 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.
