26. Discover Sumo: Stories from Yobidashi Hideo by Hideo Yamaki (Gendai Shokan, 2017)
Authors: Andy Adams and Clyde Newton are staples in the English-language world of sumo wrestling. Andy and Clyde edited and published Sumo World Magazine together later in their careers. Andy passed away in 2011 and Clyde has presumably taken over, but issues are printed sporadically at best.
Pros: The book is well organized and Andy/Clyde do an excellent job of easing the beginning reader into the world of sumo especially with terminology. The photos are excelling This book was published during the great sumo wrestling boom of the late 1980s in England so is almost 30-years old now. The pre-internet days of sumo yielded some great photos by Gerry Toff, although all the rikishi (wrestlers) have long since retired so at best it is a nice jaunt down memory lane. Andy and Clyde's proximity to the sumo world make for some fascinating stories like winning large jars of mushrooms and a year's supply of Coca-Cola...not to mention the great feats of beer drinking by some of the rikishi.
Cons: An one odd choice of organization is the history of sumo as it is embedded in the back under The National Arena section. I supposed for a beginner, this might be better left to the end, but organizationally, it probably warrants its own section. The book is also fairly large (9.5" x 12.5") so can be a slight pain to get it on a book shelf or store...especially since it is a hardback.
Cost: You can still pick copies of this up off of eBay for $15-$20, but surprisingly there doesn't seem to be any for sale in the United States at the moment. Amazon is probably your best bet to get used copies of this for under $10 in the U.S.
Overall Score: A-
