Fun fact: the name "Miyazaki" comes from 宮 miya (shrine) + 﨑 saki (small peninsula). The saki becomes zaki due to rendaku, a sound change that often happens in Japanese compound words; there is also "Miyasaki" as a variant reading of the surname without rendaku.
In any case, this means that the surname Miyazaki is essentially identical in meaning to the surname Kirkness, and the toponym Kirkenes, if we treat churches and Shinto shrines as equivalents to one another in the respective cultures.
