If good quality sake and shochu are used then this can be a great drink. However, it lacks the alcoholic bite I associate with a true Martini, so I much...
I’ve made something similar before with Korean traditional distilled soju (over 40% ABV) and cheongju/yakju (clear rice wine). They’re somewhat similar to shochu and nihonshu. Still, the 1:1 combination made sense when I tried it that way.
