Well, no, but “Yamaguchi” clearly is. And in a town like this with a substantial population of Asian descent, you rapidly adjust to seeming mismatches: see, for instance, tailor Laura Tran, or real-estate agent Wendy Chong.
“Zarina”, being a Central Asian female name, is also thought [in America] to mean “Tzarevna” (Царевна), i.e. Tzar’s daughter (compare to “Tzaritza” – Tzar’s wife).
The combo with “Yamaguchi” make it simply delightful.
Reminds me of a classmate in H.S., a Tartar girl who was called, in popular local fashion, Venera (=Venus) Ghazi-Mohamedova
