The Season 2 premiere features American manifestations of otaku, the Japanese trope that combines cutting-edge pop culture with fetishistic obsession. Included: New York's first cat cafe; a Brooklyn izakaya run by a Frenchman in thrall to Japanese anime and manga; and a California suburban mom who's a star on the international bento-box circuit. Also: Danielle gets in the sumo ring with a 600-pound opponent and then helps him make chanko nabe, the sumo wrestler's staple meal.
