Waterproof smartphones are becoming more common in Western markets, but they are hardly the norm. In Japan however, almost all phones are waterproof, and have been for nearly a decade now. According to statistics, 90% to 95% of phones in Japan are waterproof, because people need to be able to use them while they are showering.
Japanese users are apparently so attached to their phones that they even bring them into the shower. Manufacturers were aware of this unusual habit early on and realized that in order to succeed in japan, they had to make their devices water resistant. The world’s first waterproof mobile phone, the Casio Canu 502S, was release in 2005, and was soon followed by a series of Fujitsu waterproof handhelds. Before long, every company looking to enter Japanese market had to make their devices waterproof.
