On April 1, 2026, GravaStar Japan announced the domestic launch of the Mercury V60 Pro, a 60% magnetic keyboard with a Japanese layout, via their official X account.
The official X post highlights features such as original UFO magnetic switches, an 8KHz polling rate, and a 0.005mm rapid trigger. The official store lists the “Mercury V60 Pro Deluxe Edition / Dual Keycap Gift Set (Japanese Layout)” for 34,980 yen (tax included).

The product page states that it uses GravaStar’s proprietary UFO magnetic gaming switches, achieving 0.001mm actuation and a lifespan of over 100 million keystrokes through Hall effect technology and N52H magnets.
The key takeaway of this news is that while emphasizing the high-speed input performance typical of magnetic keyboards, a dedicated sales channel for the Japanese layout model has been established in Japan.
The PCB-based width is 15u. Looking at the bottom row layout, you can see that keys corresponding to Henkan and Muhenkan are provided on both sides of the space bar.
By visual estimation, the space bar size appears to be approximately 3u.

What makes this product interesting is that a brand with such a strong design identity like GravaStar has entered the 60% magnetic keyboard market, where Japanese layout models are still scarce.
With the online shop even featuring a dedicated “Japanese Layout Keyboard” category, it seems that understanding of Japan’s unique layout requirements is gradually progressing.
