Insider tip — Aki City on Kochi's Pacific coast is twinned with Helston, Cornwall (UK) — home of the ancient Furry Dance (Helston Floral Dance, held each May 8th since medieval times). This onsen bears the English sister city's name as a gesture of international friendship. Aki is also the birthplace of Iwasaki Yataro, founder of Mitsubishi (one of Japan's largest conglomerates); the city faces the Pacific Ocean and is known for fine seafood and the ancient Yasakani no Magatama sacred jewel displayed at the local shrine.
