（総務課回答823）About the question you sent to Information Center
This is Information Center for ''Immigration Services Agency''.
In regards to your inquiry, we have received an answer from the General Affairs Division as follows.
Regarding the content of inquiries, first of all, regarding the restriction of the scope of action, it is under the jurisdiction of the Ministry of Health, Labor and Welfare, so please ask the Quarantine station of the Ministry of Health, Labor and Welfare.
Next, regarding whether the media who entered the country as a person involved in the Olympics and Paralympics could conduct interviews and photographs that had nothing to do with the Games, the fact that they were engaged in activities that had nothing to do with the purpose of entry declared when they entered Japan. If it becomes clear objectively, they may be asked to confirm the purpose of entry in detail the next time they enter Japan.
Lastly, how long they can stay after the end of the Olympic Games is until the expiration date for which they have been granted permission, but if it becomes objectively clear that they have stayed beyond the planned stay period declared at the time of entry. Similar to the above, the next time they enter Japan, they may be asked to confirm the purpose of entry in detail.
We hope you’ll be able to understand the immigration administration in the future.
