India, Nov. 22 -- She's known for "tidying up" and "sparking joy," but there is more to Marie Kondo than a fervent desire to help you better assess your mess. Across book tours and conferences, it became clear that her audience, while interested in how to keep their lives tidy, was also keen to learn about her and the culture so intrinsic to her methods. Some of the answers take shape in Letter from Japan. Written with Marie Iida, her interpreter on the Netflix series Tidying Up..., Kondo uses the book to reflect on some of the myriad questions she has received, by examining the Japanese customs she grew up with: tea ceremonies, the art of taking care of gardens, the power of the passing seasons. She does this with her trademark gentle wisdom. The book isn't only a response to her audience's wish to know more about Kondo. It is a testament for her three children: a documentation of the foundational elements of their culture, and an attempt to help them understand their world. With subtle and lyrical prose, Kondo embarks on her most personal and affirming book yet, unveiling for her readers the customs, traditions and practices that spark joy for her, and also helping to preserve them for future generations....
