- Title: Labyrinth of Civilization - Author: Mototaro Kagawa - Publisher: PHP Institute - Series: Over 2.4 million copies sold - Price: ¥1,300 Thank you for viewing. This is a valuable signed book by Mr. Mototaro Kagawa, left before his passing, and it is new. This item is currently difficult to obtain. I am still hesitant to list it, so please be aware that I may remove it suddenly. It was kept in a new, unopened state in a plastic bag with care. It was opened for the purpose of taking photos this time. The condition is extremely good, but as it is a signed book that has been in the author's hands once, please refrain from purchasing if you are looking for perfection.
