Okay kiddo, let me explain Japanese place names to you!
In Japan, people use a combination of kanji (Chinese characters) and hiragana (one of the Japanese writing systems) to write their place names. These names often describe the location, scenery, or history of the location.
For example, let's imagine there's a town called "Yamauchi." The kanji used to write this name mean "mountain inside." This could be because the town is located in a valley surrounded by mountains, or perhaps there is a prominent hill or mountain within the town's limits.
Another example is "Ryokuchi Kouen," a park in Osaka. The first part of this name means "green land" and the second part means "park." So you can imagine that this park is probably quite green and lush!
Sometimes, a Japanese place name will use hiragana to write out the pronunciation of the name in a way that isn't possible with only kanji. For instance, the city of Sapporo is written using hiragana "さっぽろ" instead of kanji. That's because the kanji for Sapporo would be difficult to read and pronounce correctly.
So, there you have it! Japanese place names use kanji and hiragana to describe the location, scenery, or history of the place.
