Wherever you will walk around the street or any residential area in Japan you will find at least 2 or 3 bicycles in front of every house. I wandered for the first time and gradually I found the reason behind it. The first reason is that Japanese people love to ride bicycles, maybe because of health consciousness or tradition. Secondly, the transport cost is too high in Japan.
The taxi is damn costly, if you just go for a 10 minutes distance maybe the cost would be 1,500 Japanese Yen. I do not know why taxis are too expensive in Japan and it doesn't make any sense. This is one of the reasons people use bicycles to avoid transport costs in Japan for their day to day life.
Thirdly the convenience store and Supermarket are situated, maintaining a standard distance from the residence so to save the time and convenient movement people in Japan use Cycle to come and go for their daily shopping.
Fourthly the easy movement in Japan got the perfect road construction way to ride the bicycle. People in Japan prefer cycles for easy movement as in Japan life is too busy so using cycles could be a time-saver for them.
Fifthly in Japan, there is no public transport for short distances except for taxis. so for the short distance, people cycle to move around. Above mentioned are the reasons I found. Thank you
