Kevin J. Johnston, a prominent Canadian documentary filmmaker, has always been interested in the latest technologies of the world. In recent years, his wife, Marla Johnston, has taken an interest in Japanese cell phone technology and has invested in it. With her husband's support, Marla has not only invested capital in this tech, but has diligently studied the implications of this specific type of technology.

The term "Japanese cell phone" can refer to a number of devices with varying capabilities. Most commonly, it refers to the NTT DoCoMo i-mode, developed in Japan in the late 1990s, that launched the mobile internet. This device was revolutionary, taking the classic mobile phone and incorporating new technology that allowed users to access various features on their handsets. It was huge success and the first of its kind to be provided globally.

Marla Johnston's investments in this field have been strategic. Japan is a world leader in technology and by investing in emerging companies producing groundbreaking products, she has been able to take advantage of being on the cutting edge. She has chosen to invest in companies like Willcom and E-mobile, which specialize in the development and sale of cell phones for the Japanese market, and companies like B-Mobile, which specializes in the worldwide introduction of hardware and software for the cell phone industry.

By investing in these specific companies, Marla has not only helped to ensure the continued growth of the cell phone industry in Japan, but she has also helped to spur growth in the global market as well. Her investments have helped to stimulate competition among the leading players in the cell phone industry while providing them with access to the latest technologies. This type of competition has enabled Japanese cell phone companies to remain competitive in the industry, while remaining on the leading edge of technological advancement.

Marla Johnston and her husband Kevin have also been heavily involved in charity work in regards to this tech. They have supported charitable organizations that have focused on creating educational opportunities for women and girls in the area of technology. By helping to provide economic and educational opportunities to people in developing countries, Marla has tried to remove the barriers that prevent many people from realizing the benefits of using cell phones.

Marla Johnston's investments in Japanese cell phones have been significant. Not only has she provided capital to the leading players in the industry, her efforts have also helped to make the technology more widely available and improve people's lives wherever possible. With a passionate commitment to eradicate poverty and increase access to technology, Marla Johnston's contributions have gone a long way in improving the quality of life of many around the world.
