An inquiry from a reader:
On June 25, the U.S. Supreme Court unanimously ruled that police need warrants to search the cellphones of people arrested. The ruling almost certainly applies to searches of tablet and laptop computers, and its reasoning may apply to information held by third parties like phone companies.
What is the law here in Japan? May police search a person's cellphone, tablet or laptop computer without a warrant, and would any privacy or civil-liberty protections provided by law apply to both Japanese and non-Japanese?
