Naoki Hino is a 32-year-old Chanko restaurant owner. Chanko is a stew that's eaten in large amounts by sumo wrestlers to gain weight. Because of Sumo's popularity, Chanko restaurants are becoming extremely successful among the general public. But Naoki's restaurant has the advantage of being one of the few owned by a real sumo wrestler. Photograph: Reed Young

Konishiki Yasokichi is a 45-year-old one of Japan's most recognisable celebrities. Now that he's retired from the sport that made him so popular, he's become a hip-hop artist and host of his own children's television show. He was the heaviest sumo wrestler of all time weighing 580 pounds(264 kg). Two years ago he underwent gastric bypass surgery and has lost much of the weight that previously threatened his health.

Sanyutei Utamusashi is a 41-year-old retired sumo wrestler who practices the art of Rakugo, a form of entertainment that involves complicated yet comedic storytelling.

Yasuyuki Hirose is a 32-year-old retired sumo wrestler who's become famous in Japan for his part in a comedy trio that performs on TV. His obesity related difficulties are often the topic of the group's jokes. In particular he's known for being able to drink a two-litre bottle of orange Fanta in only ten seconds.

Yoshitoku Tashiro is a 33-year-old retired sumo wrestler who now works as a writer. He recently published a best-selling book about the real life of a sumo wrestler, including topics such as how to meet a girl, how wrestlers travel, what they eat, and what they do in their spare time. He originally wrote the book with the intent of teaching young wrestlers about the kind of life they might lead, but it ended up selling more to the masses out of curiosity for a sport that is rarely covered with a personal viewpoint.
