incidentally , taxis with doors that customers do not need to open themselves can rarely be seen overseas , and thus many foreign tourists visiting japan are surprised by the automatic door (the information on automatic taxi doors is often introduced in some guide books for foreigners to japan; in a contrasting situation , japanese should be careful when they take a taxi in foreign countries because the door does not open automatically ). なお、ドアを客があける必要の無いのは日本以外にはほとんどなく、日本を旅する外国人は驚くことが多い（日本旅行向けガイドブックに紹介されていることがある。逆に日本人が外国でタクシーに乗ろうとするときは、ドアは開かないので注意）。
