ヒントはタクシーの一人辺りの台数は「観光地か交通の便が悪く、かつ大都市であること 」が多くなる条件です。

I changed koto strings now,in the morning.

It requires skill to change koto strings,but i've been get the hang of it,so it took only 15 minuts.

The intersting story I listened from taxi driver in kyoto. kyoto is the second largest number of taxis because it's most popular tourist destination in Japan.

So,which prefecture is the largest do you think?

I'll answer the next diary lol

The hint is the number of taxis increases where the place of popular tourist site, or where train or bus transportation net does not developed and capital large city.
