Ichitaro continues to be upgraded: Where will 41 years of evolution in Japanese word processing software lead?

Ichitaro, the Japanese word processor, has reached its 41st year and continues annual updates with a focus on Japanese-language publishing workflows.

The latest version adds generative-AI text rewriting, alongside stronger support for novel writing and self-publishing.

Its long-running appeal comes from features like vertical writing and ruby text that mainstream tools such as Microsoft Word and Google Docs do not emphasize.

By refining publishing- and creative-writing-oriented functions, Ichitaro remains a niche but durable choice in education, government, and the literary community.
