How do you write you name Ziza in japanese?

Answer 1

ジザ /ji za/. They don't have 'zi' syllable, however it still remains optional to create it yourself through knowing what to do with Katakana syllabery. If you insist on not using 'ji' for syllable 'zi' (it's the common way and comprehensible to a Japanese person), you can use ゼィ /zi/ instead, resulting in ゼィザ /zi za/; definitely comprehensible by Japanese and also readable, just much less common.
