I recently got a copy of this book, How to Read Japanese Poetry (New York; Columbia University Press, 2019) ISBN 978-0231186834, and have been enjoying it thoroughly. Steven Carter is the author of several books translating Japanese poetry into English, and his Traditional Japanese Poetry: An Anthology (Stanford; Stanford University Press, 1993) ISBN 978-0804722124 is usually the first book I recommend to people who want to explore Japanese poetry. This book is a little more intimate, where Carter presents poems in a variety of styles, with translation notes and historical background. Less poems than his earlier book, but he digs down into further detail. If you are at all interested in Japanese poetry, definitely add this book to your library. https://www.amazon.com/Read-Japanese-Poem-Steven-Carter/dp/0231186835
