The Sanyo Katana was a series of flip-style mobile phones manufactured by Sanyo Electric Co., Ltd. and primarily offered through Sprint Corporation in the United States during the mid-2000s. The name "Katana" was chosen to evoke the slim profile and sleek design of the traditional Japanese sword, reflecting the phones' emphasis on a thin form factor for the time.
Introduced in 2006, the original Sanyo Katana was notable for its relatively slim clamshell design, featuring both an external color display and an internal color screen. It was marketed as a stylish and compact device, appealing to users looking for a feature phone with a modern aesthetic. The series saw several subsequent iterations, including the Katana II, Katana DLX, and Katana Eclipse, each offering incremental improvements such as enhanced camera capabilities, larger displays, or minor design refinements, while maintaining the signature slim flip-phone form factor.
The Sanyo Katana line was part of a broader trend in mobile phone design during the 2000s where manufacturers focused on reducing device thickness. It was a popular series for Sprint customers, contributing significantly to Sanyo's presence in the North American mobile phone market before the widespread adoption of smartphones began to fundamentally shift consumer preferences. Sanyo's mobile phone division was later acquired by Kyocera.
