When I was a middle school student, one of my favorite Japanese authers was Morio Kita. He is a son of a famouse Japanese tanka, thirty-one syllabled verse, master and wrote lots of interesting books. I enjoyed his books especially essays. His essays are sprinkled with humor and have a lot of laughs.
My first book of his essay was どくとるマンボウ航海記, The Voyage of Dr. Manbo. He wrote in the book about his experience of a voyage as a ship's doctor. The episodes were silly and funny. It's hard to explain how funny the book is. He didn't write about nice tourist spots nor delisious foods. It was published in1960. It's an old one but I highly guarantee you'll enjoy reading it!
