Update: so after being called out of using racist slang "Oriental", the questioner had changed the word "oriental" to "Asian". OK, thank you. But still, there's no such thing as "typical Asian" city. There's no such thing as "good Asian name", just like there's no typical European name, or typical North American name. Everything else I said in my original answer still applies. It goes beyond the word "oriental", since the questioner still takes "Asian" as a whole, and refuse to recognize the huge diversity with in Asia.
Hello aspiring writer who want to write about "oriental" styled fantasy works, I'm someone who grow up in an exotic "oriental" city, of an exotic "oriental" country. And let me tell you something about our "oriental" culture, so you can whitewash it and fit in your basically western fantasy story.
First of all, please don't use the word oriental, it is insulting. It's like asking "what would be a good nigger name for this fake black story I write that features black and African American subculture I know nothing about".
No. there's no such thing as "oriental". There's China, Japan, Korea, India, Thailand, Vietnam, Cambodia, Indonesia, Philippine, Singapore, and many many other Asian countries and culture. While some part of our culture might over lap, for example, many Asian people use chop sticks to eat food, each of these cultures are vastly different from another, even within the same country, each city would has its own flavor and local micro-culture, depend on its history, location, weather, people...
You wouldn't go around asking "what would be a good "white people" town name", because there's no such thing as "white town". There're American town, British town, French town, German town, and all of them are different, depending on the language, their name would be different.
What is the context of this city? what is its history? how did it end up having a wall in the middle? What is the different between the different sides of the wall? Are the two halves friendly to each other or they're hostile? All of these plays into the naming of your town. Town names don't come out of the vacuum. And it certainly don't come from asking internet about a "good oriental name".
If you want to write about a location inspired by an Asian city, PICK A CITY AND DO YOUR DAMN RESEARCH!
There's no "blank boring oriental city" that can be located in China, Japan, Korea, Indonesia or India.
Writing shouldn't be this careless. Something so important as a town name, a town with such unique feature, shouldn't come from asking internet. And for fuck sake, don't use "oriental" because you want to be fucking exotic! Asian people are people, we're not some exotic birds you can go watch and be amused in our exotic habitat!See Questions On Quora
