Seven models will be available: two ivory limited edition models of RC1, one ivory limited edition model of R4, and four new color models of R4.

Both are available in limited quantities and the release date is announced as March 16, 2026.

The new lineup features new and expanded options in terms of color, while maintaining the capacitance non-contact method and hybrid connections that have been typical of REALFORCE in the past.

Ivory-type products, in particular, are likely to attract attention due to their recent retro orientation and compatibility with desk environments.

List of models announced

RC1 Ivory Limited Model Overview

The RC1 ivory limited edition model features a compact configuration with 82 keys arranged in Japanese, and is available in 45g model C1HJ51 and 30g model C1HJ53.

Both support Bluetooth 5.0 and USB connectivity and come in quiet, APC-compatible, PBT keycap, sublimation printing, and kana keycap configurations.

It measures 130 x 295 x 39 mm and weighs 0.6 kg.

R4 Ivory Limited Edition Overview

R4 Ivory Limited Edition R4HA51 is a full-size 112-key Japanese-language model with full-size keys, 45g, quiet, and APC-compatible

It supports Bluetooth 5.0 and USB hybrid connectivity and has an ivory body with ivory/gray keycaps.

It measures 146.5 x 452 x 39 mm and weighs 1.3 kg.

R4 new colors are blue and brown

Two new R4 colors will be available: a metallic blue body with a blue-gray keycap and a metallic brown body with a brown keycap.

Both are 45g, Japanese-language layouts, and are available in 112-key and 91-key versions.

All of the new color models also feature no kana printing.

Summary｜Some call for ANSI layout

This is to report on the news of the new color lineup for the REALFORCE R series.

This announcement can be noted as a move by REALFORCE to expand not only performance but also appearance options.

The new R4 color is likely to appeal to users who are looking for something a little different from the traditional REALFORCE, especially the ivory limited edition model, which is a good match for a more classic desk environment or a more relaxed workspace.

While the product specifications themselves maintain the solidity typical of REALFORCE, this is an additional line that strengthens the enjoyment of choosing from a variety of colors.

This is an arrangement based on official specifications and announcements, and the texture and color of the actual device may differ in impression between the photos and the actual product.

On the other hand, the comments that follow in the tree of the post in question called for an ANSI layout.

After all, REALFORCE has many programmers who are fans of the ANSI layout, and I have the impression that they are waiting for the new colors to appear.

We look forward to additional developments in the future.
