Editing Ichitaro (word processor) (section)

=== Arrival of Microsoft Word ===
Microsoft released the first Japanese version of [[Microsoft Word]] for Windows in 1991. Four years passed before Ichitaro 5 was released for Japanese DOS platforms in April 1993. The next month, Microsoft released the Japanese [[Windows 3.1]] and the first Japanese version of [[Microsoft Office]], which included Word 5.0 and [[Microsoft Excel|Excel]] 4.0.<ref>{{Cite news|title=マイクロソフト、ウィンドウズ3.1対応ソフト―パッケージを投入|date=1993-06-17|work=[[Nikkei Sangyo Shimbun]]|page=6}}</ref> Its successors shipped 200,000 copies per month in late 1994.<ref>{{Cite news|title=マイクロソフト、「オフィス」「ワード」増産―倍の月20万本に。|date=1994-10-18|work=[[Nikkei Sangyo Shimbun]]|page=6}}</ref> JustSystems barely completed a Windows adaptation of Ichitaro in December 1993,<ref>{{Cite journal|year=1993|title=ジャストシステムが日本語Ｗｉｎｄｏｗｓ３．１用の一太郎を発表|journal=[[ASCII (magazine)|ASCII]]|volume=17|issue=11|issn=0386-5428}}</ref> but Microsoft took over the market dominated by Ichitaro and [[Lotus 1-2-3]].

As of 1997, a Japanese media website reported that 64% of readers using Microsoft Word, and the main reason was that they used it in offices and schools. The rest of 35% were using Ichitaro, and the main reason was that the IME of ATOK was convenient.<ref name="impress_19970326">{{Cite web|url=https://pc.watch.impress.co.jp/docs/article/970326/result.htm|title=プレゼント付き読者アンケート第16回「対決！？一太郎 VS Microsoft Word」集計結果発表|date=1997-03-26|website=Impress PC Watch|access-date=2019-04-24}}</ref>

In 1998, the [[Fair Trade Commission (Japan)|Japan Fair Trade Commission]] informed Microsoft of an [[Anti-competitive practices|unfair trade]] that they forced personal computer manufacturers to bundle with Excel and Word against the request of a bundle with Excel and Ichitaro.<ref>{{Cite web|url=https://pc.watch.impress.co.jp/docs/article/981124/koutori.htm|title=公正取引委員会、マイクロソフトへの勧告内容をPDFファイルで公開|date=1998-11-24|website=Impress PC watch|access-date=2019-03-31}}</ref>

Ichitaro Ver.5 was ported to the [[Apple Macintosh|Macintosh]] and to [[OS/2]]. In May 2003, the release of a [[Linux]] version was announced. Compact versions, "Ichitaro dash" and "Ichitaro lite" are produced for [[laptop PC]]s. As [[office suite]], "Just home" is also available. "Ichitaro smile" is targeted at elementary school students and "Ichitaro jump" at middle and high school students.

On 1 February 2005, sales and production of the software were frozen pending an appeal by the company against a ruling of the [[Tokyo District Court]] which states that there is a [[Patent infringement|breach of a patent]] owned by [[Matsushita Electric Industrial Co., Ltd.]]<ref>''The Yomiuri Shimbun'', pp.1 Tokyo morning edition, 2 February 2005.</ref> However, on 30 September 2005, [[Intellectual Property High Court|Intellectual Property High Court of Japan]], which was newly formed in April 2005, has granted JustSystems’ appeal. Because this judgement became a final decision in October 2005, the original decision sentenced by the Tokyo District Court was overturned.<ref>The decision of case 2005 (Ne) 10040, Intellectual Property High Court of Japan - 30 September 2005</ref>

In 2009, JustSystems became a subsidiary company of [[Keyence]]. In the 2010s, they focus on [[correspondence education]] and [[enterprise software]] although Ichitaro and ATOK continue to be developed.<ref>{{Cite web|url=https://toyokeizai.net/articles/-/160652|title=あのジャストシステムが大変貌を遂げていた―今や収益柱は｢一太郎｣｢ATOK｣ではない|last=島|first=大輔|date=2017-03-05|website=[[Toyo Keizai]]|access-date=2019-03-31}}</ref>
