A subscriber commented that his こうきょ, meaning "Imperial Palace," was mistaken for とうきょう. I’m gonna guess what happened and tell you how you can prevent it.
I think he said こうきょ as こうきょう based on the romaji spelling "Koukyo," with the accent of "Tokyo" in English. the "o" as [ou].
You might think きょ and きょう sound the same, but they don’t. They sound very different to Japanese people. Romaji can be confusing. It’s best to learn hiragana and katakana for clear pronunciation.
Another thing is the pronunciation of きょ. This is きょ, not きよ. So こうきょ and こうきよ sound very different as well.
Specifically, きょ is one mora, きよ is two mora and きょう is two mora.
One mora and two mora sound very different.
It’s best to learn about Japanese mora as well.
