Over 90% of cellphones sold in Japan are waterproof because many Japanese people like to use them in the shower or bath. Bathing is an important Japanese daily routine that is thought to provide health benefits such as relaxation and self-reflection. Despite cramped living spaces, Japanese bathtubs called furo are typically larger and deeper than American bathtubs. Many furo are deep enough to cover the bathing person's shoulders when sitting. Since so many people are using their cellphones while in the bath, waterproof cellphones began to rise in popularity. This has also given the rise in popularity for waterproof televisions.
