上面差班说的对。日本领馆网页上明确说明，绿卡持有者也必须办理签证。

办理旅游签证时带以下文件：

A valid passport with atleast 6 months validity remaining

One 2"x2" passport-type photo (taken within 6 months)

One visa application form fully compelted and signed

An alien registration card (i.e. U.S. green card) if you are a permanent resident of the U.S.

An I-20 form if you are a foreign student in the U.S.

Proof of long-term resident status in the U.S. if you are neither a permanent resident nor a foreign student

Airline tickets to and from Japan or flight confirmation
