This is the second model with an original button layout tailored to the player's hand shape and play style, adopting a layout that makes it easy to use all five fingers including the thumb.

This model is available for pre-order from June 7, 2026 (Sunday) on the GRAPHT official EC site (GRAPHT OFFICIAL STORE). Other arcade controller parts can also be ordered at the same time. As a pre-order bonus, a special sticker featuring a newly shot photo of Dogura is included.

'iO Dogura Edition' An original layout with 8 buttons + thumb button that fulfills Dogura's wishes

'iO Dogura Edition' is a special model that incorporates Dogura's attention to detail for users who continue to play with a joystick. It adopts the easy-to-carry 24φ model ('iO' M size) and, at Dogura's request, has an original layout with 8 buttons plus an additional button at the right thumb position.

The arcade controller that Dogura aimed for: 'An arcade controller that won't be an excuse in matches'

This model was fully supervised by Dogura based on his desire to 'make an arcade controller that won't be an excuse in matches.' Aiming to leave as little regret as possible—'I wish I had this' or 'I wish I could do that'—he pursued an operating environment that can be used with peace of mind from daily practice to actual matches.

Why Dogura chose 'iO'

Dogura sees 'iO' as having a balance of stability that barely moves even under intense key presses and a weight that makes it portable. The ability to confidently press keys and easy movement at venues—both qualities are why he chose 'iO'.

Second original button layout model tailored to play style

'iO' is an arcade controller that can be optimized according to each player's hand shape and operation habits. 'iO Dogura Edition' is the second model with an original button layout tailored to a player's personal play style. Going forward, 'iO' will continue to pursue such customization, shaping user feedback and contributing to creating an environment where players can win more easily.

'iO Dogura Edition' is available only in M size, lever model (panel only: 13,200 yen including tax).

The case-only set starts at 30,580 yen including tax, and the case + parts set, which includes basic arcade controller components such as Brook PCBs, cables, Sanwa Denshi buttons, and levers, is 52,888 yen including tax. Existing M size users can adopt the 'iO Dogura Edition' layout by replacing the panel.
