Is my explanation correct for why locations CAN be the direct object of motion verbs?
Both in English and Japanese, it is commonly agreed that LOCATIONS CANNOT MOVE, but instead we (as in ANIMATE BEINGS) move.
But, in Japanese it ISN'T necessary to have a word like "through" to describe the direct object of motion verbs, because LOCATIONS ARE STATIONARY, and it's just a superfluous step.
I'm paraphrasing this from "Tae Kim's Guide to Learning Japanese: Japanese Grammar Guide".
She writes, "Unlike the direct object we're familiar with in English, places can also be the direct object of motion verbs such as あるく and はしる. Since the motion verb is done to the location, the concept of direct object is the same in Japanese."
