Spanish Ambassador Miguel Navarro is eager to turn the eyes of Japanese to the lesser known historical footnotes that connect Japan and his country as the 400th anniversary of bilateral exchanges is celebrated.

"The two countries have had a deep relationship for 400 years devoid of any conflict or confrontation," Navarro points out.

When Spanish Prime Minister Mariano Rajoy visited Japan last week to meet with Emperor Akihito and Prime Minister Shinzo Abe, he also went with the 64-year-old Navarro on a trip to Fukushima Prefecture.
