Background context: white woman, Air Force baby, moved to to America with my dad when he got redeployed when I was 11, scrambled to learn English, polished up my English with shit like Magic the Gathering, Futurama, and later, Disco Elysium, and am lately struggling to maintain my Japanese so I don’t feel linguistically homeless.

That said: it mostly just depends on whether you want stylistic choices of picking more English loan words (very modern, funky-style) or if you’re more of a traditionalist. Sometimes I’d use ゼロ when giving driving directions, but I’d also use 零 when telling time.

So yeah, I don’t know.

Edit: using 丸 in both of these contexts is weird but sometimes I’d use 丸 in phone numbers. Fuck, who opened this can of worms?
