The appearance of Japanese mobile phones is indeed attractive, but the large body size is not something everyone can accept. It's not uncommon for Japanese phones to have large screens of around 3.5 inches, which inevitably results in a bulky design. When the phone becomes too large, it jiggles uncomfortably in the pockets of jeans, and the chest pocket of a shirt can no longer accommodate it. Moreover, many of these large Japanese mobile phones adopt a flip design, which causes a lot of inconvenience when using the phone.
