Message from CEO

e-Jan Networks aims to get customers constantly saying 'e-Jan!' It is important that we look from the customers' point of view, and that our customers are satisfied with and continue to favor our products. 'e-Jan!' is Japanese for 'That's cool!' or 'I like it!' This is the key phrase that expresses our vision.

Shiro Sakamoto

In order to achieve this, we put priority on members' high level of moral, enthusiasm, and interpersonal respect at work. These will lead to a positive working environment where members appreciate each others' contributions, which effectively reaches out to our customers. This dynamic enables us to create a product that continues to gain 'e-Jan!'

We also place importance on diversity; members from different countries, races, ages and sexes, are continuously working hard together by concentrating their wisdom, in a proactive, enthusiastic, rational, creative, and flexible way. Diversity enables our products to constantly be creative and valuable in this quickly-changing IT business world.

Thanks to our customers, CACHATTO has evolved into the product that it is now. Through CACHATTO, our goal is to gain, on a global scale, 'e-Jan!' We strongly believe this coagulated energy of enthusiasm will lead us to a next-generation ideal organization that can contribute globally.

Shiro Sakamoto

e-Jan Networks Co, CEO
