Japan Prime Minister Shinzo Abe feasted on bean soup and rice cakes at the humble home of Philippine President Rodrigo Duterte on Friday, and sampled the down-to-earth living of a volatile new friend who is shaking up the status quo in Asia.

With the backdrop of family photos, cups hanging from kitchen cabinets and clusters of used beer and wine bottles, Abe ate Duterte's favorite breakfast in Davao City and was given a tour of his creaky, two-storey house, including a bedroom featuring the mosquito net he sleeps under on most weekends.
