Fifteen fundamental concepts of Japanese thought, fifteen emblematic places of the Japanese country and a single objective: to immerse yourself in the essential principles of Japanese philosophy, spirituality, culture and society. Le Yen Mai, a writer of Vietnamese origin born and raised in Switzerland, brings us closer to fifteen key ideas of Japanese thought, from the best known in the West, such as the wabisabi (praise of imperfection) or the ikigai (the reason for existence) , even others as attractive as hanasaki (the Japanese art of living longer) or Y?gen (being part of the universe). From the beauty of the landscapes that she evokes and the clarity of a person accustomed to building bridges between East and West, she immerses us in the essence of Japanese wisdom, resorting to simple examples with which the reader will identify. A metaphorical tour of the land of the rising sun, especially recommended for those who want to integrate Zen into their life, their home and their way of thinking.
