How to say and write domain in Japanese?

LS, you all speak very well.

If it is an ordinary Japanese conversation, it is really a commonly used "ぶんや wenya".

In addition, there is another saying: "ゾーン", which is a foreign word of zone.

For example: Tiezuka District in Tezuka, Tezuka Domain.

(I wonder if LZ wants to ask this? Hehe)
