Which district in Tokyo has the tightest supply-demand balance of parking lots?

A parking lot (British English: car park), also known as a car lot, is a cleared area that is intended for parking vehicles. Usually, the term refers to a dedicated area that has been provided with a durable or semi-durable surface. In most countries where cars are the dominant mode of transportation, parking lots are a feature of every city and suburban area.
