This is an explanatory book for the Takaosan Iroha Haiku Karuta, published in 2015 at Yakuoin Temple on Mount Takao. I believe I received it as a thank you for donating to Yakuoin Temple. Before publishing this book, Yakuoin Temple created the "Takaosan Iroha Haiku Karuta" and distributed it to its parishioners. They created this book in 2015 to commemorate the 640th anniversary of the temple's reconstruction. Each haiku is explained, and the accompanying illustrations are lovely. The book size is 21cm x 30cm and about 0.7cm thick (please allow for some error). I have kept it in the bag I received it in, so there are no stains or blemishes on the book. I recommend it to those interested in Mount Takao or haiku. Thank you for looking.
