Please complete a Reproduction Request Form prior to reproducing any content that is labeled either "インターネット公開(裁定)" (licensed by the Commission of the Agency for Cultural Affairs) or "インターネット公開(許諾)" (used with permission of the copyright holder).

Please check "Access Restriction" with the following procedures:

First, make sure that the content (image) is displayed in the Content Area.

Second, check "インターネット公開(保護期間満了)"("Copyright expired" written in Japanese) in the "Access Restriction" of the Bibliographic Information Area.
Please note that even if when "インターネット公開(保護期間満了)"("Copyright expired" written in Japanese) is displayed in the "Access Restriction" of the Bibliographic Information Area, "Access Restriction" information can be different depending on each image.

Access restrictions for each volume or issue might differ from the access restrictions for aggregate titles, so please be sure to specify individual volumes or issues.

After selecting the volume or issue you wish, the image should appear in the content area.
