Oh wow this looks great!! The sculpting on your Mt. Fuji looks very realistic, and man those cherry trees along the river are gorgeous <3 Your world definitely evokes the feeling of Tokyo, keep up the great work! I'll be so happy to watch this world evolve, I love all things Japanese :D you should share a bunch more pictures!!
Just a suggestion, if you're not opposed to using "custom" terrains (some are actually custom, some are pulled from EA worlds), they can really add some realistic touches to a world! Modthesims and Nilxis's website have some really pretty terrains to download! Especially for rock and grass, they look much more realistic than the stock EA terrains :)
