The same year, Ichitaro was released as its definite successor. Ichitaro's system disk contained [[ATOK]] 4 and a runtime version of [[MS-DOS]] 2.11. It allowed users to use other MS-DOS applications with Japanese language support.<ref name="monthlymicom_199202" /> The biggest competitor, {{Nihongo|Matsu|松}}, was released in 1983 by {{Nihongo|Kanri Kōgaku Kenkyūjo|管理工学研究所}}. It gained speed from being written in [[assembly language]] and natively ran on PC-9801, but Matsu's Japanese input method couldn't be used for other applications. Ichitaro had plenty of typesettings options, but Matsu did not. Also, Matsu was priced at ¥128,000 before Ichitaro came out.<ref name="katakai_1988">{{Cite book|title=パソコン驚異の10年史―その誕生から近未来まで|last1=片貝|first1=孝夫|last2=平川|first2=敬子|publisher=[[Kodansha]]|year=1988|isbn=4-06-132721-6|pages=55–85|language=ja|chapter=日本語ワードプロセッサの歴史}}</ref>

The first version of Ichitaro has shipped 29,000 copies. Ichitaro Ver.2 has shipped 80,000 copies. Ichitaro Ver.3 was the first version ported for other Japanese DOS platforms. It has shipped more than 300,000 copies until 1991. Total shipments of Ichitaro reached one million in November 1991.<ref name="monthlymicom_199202" /> Contrary to the Japanese personal computer market expanding into beginners, Matsu oriented for power users, so Ichitaro overtook it.<ref name="katakai_1988" />

Ichitaro Ver.4 was released in April 1989. It had a proprietary [[operating environment]] called {{Nihongo|Just Window|ジャストウィンドウ}}, like [[Lotus Symphony (MS-DOS)|Lotus Symphony]]. Three minor versions were released because it was buggy. The stable version was 4.3 released in December 1989.<ref name="ichitaro_hist" /><ref name=":0">{{Cite web|url=http://www.ichitaro.com/history/tw04.html|title=一太郎Web：一太郎ヒストリー 一太郎Ver.４|date=2010-09-01|website=一太郎Web|publisher=JustSystems|access-date=2019-03-31}}</ref> ATOK 7 was bundled with Ichitaro 4, and was available as a standalone product in 1992.<ref>{{Cite web|url=http://www.justsystem.co.jp/atok/story/index.html|title=先進の日本語システム「ATOK」の進化|date=1998-10-23|publisher=JustSystems|archive-url=https://web.archive.org/web/19990202014635/http://www.justsystem.co.jp/atok/story/index.html|archive-date=2 February 1999|access-date=2019-04-22|url-status=dead}}</ref>
