　　A young woman sits alone in café sipping tea and reading a book. She pauses briefly to write in a nearby notepad before showing her words to a passing café waiter: "Where are the toilets please?" This is a familiar scene in Tokyo's so-called "silent cafes", where customers are not allowed to speak, and only communicate by writing in notepads.

　　The concept rises by a desire to be alone among your Japanese, a situation brought by economic uncertainly, a shift in traditional family support structures and the growing social isolation.
