in contrast to the wide available space in the states have a look on the limited areas of parking lots in Japan.
This shows the parking lot of my apt. block and the cost per month ist abt. 500 bucks/parking lot And for a bicycle one has to pay 15 bucks, if you are lucky to get a free space. My "byce parking lot" is on floor 8 on the balcony of my apt.
Have also a look on my report about the BMW Club of Japan meeting under community, Treffen. Might be interesting for you.
