Uchujin (with guest vocalist Mariko Goto) is a Japanese music credit centered on a collaboration between Uchujin and guest vocalist Mariko Goto. It is not presented as a standard solo release; instead, the featured vocal performance by Mariko Goto defines the identity of the credit and distinguishes it from other Uchujin-related entries.
For listeners cataloging Uchujin releases, this version is the clearest reference point for the Mariko Goto collaboration. Guest-vocal credits like this are commonly used to identify a specific performance or arrangement, and this entry makes that relationship explicit by naming the pairing directly.
