My Strengths

My strengths go beyond simply reviewing and supervising keyboard products.

Through the continuous operation of “Greenkeys,” a media specializing in keyboards, as a performance-based business, we have cultivated a perspective that, when looking at a product, includes “who is it suitable for,” “which appeals stick,” “where does it cause disengagement,” and “where should CV points be placed?

Therefore, I am uniquely qualified to consult with you not only on product specifications, layout, and keycap supervision, but also on the design of the product’s appeal in the Japanese market and how it will look when sold.

In 2026, through an advance review of the Keychron x Gizmodo Japan “Nape Pro,” on-site coverage and analysis of the Lofree Tokyo Pop-up, and hands-on coverage of the Vortex M50, we will go beyond mere reviews to provide advice on appeal design and exhibition context in the Japanese market, We provide not only reviews, but also advice on how to design the appeal, exhibition context, and brand presentation in the Japanese market.

We also continue to receive consultation on keycaps and sequence supervision, and are involved not only in confirming product specifications, but also from the perspective of how the product will be delivered to users and how it will look as a product.
