What makes G♯ Iwato different
Iwato uses five notes (1, ♭2, 4, ♭5, ♭7) and has neither a third nor a perfect fifth. Its two half steps, 1 to ♭2 and 4 to ♭5, sit next to two gaps of a major third, ♭2 to 4 and ♭5 to ♭7, which makes it sound sparse and unresolved. Every note belongs to Locrian on the same root; Iwato just leaves out the ♭3 and ♭6. With no fifth, the tonic never settles, which suits slow, meditative music. On G♯, G♯ Iwato is G♯ Locrian (G♯ A B C♯ D E F♯) without B and E.
