The portable yama rajio (mountain radio) was specifically made for use in remote areas. The company classified 117 Japanese mountains into 20 different areas. Hikers and climbers can listen to radio programs just by inputting the relevant area code.
Sony is targeting Japanese mountain climbers and hikers with the new device. The radio can receive analog FM/AM and comes with a mono speaker. Measuring just 58.3×91.7×15.1mm, its size is comparable to that of a business card.
The Japan-only radio will be priced at $120.
