The company is listed in the First Section of the Tokyo Stock Exchange (which is reserved for large corportations)http://www.nikkei.com/nkd/company/?scode=6916&ba=1. As  states, the consensus is that public listing by itself is not sufficient to establish notability, "However, sufficient independent sources almost always exist for such companies, so that notability can be established using the primary criterion....Editors coming across an article on such a company without such references are encouraged to search (or request that others search) prior to nominating for deletion, given the very high (but not certain) likelihood that a publicly traded company is actually notable according to the primary criterion." A search of Japanese business and IT news sites finds plenty of coverage of both the company and its products: http://www.itmedia.co.jp/pcuser/articles/1312/16/news006.html, https://www.weekly-economist.com/2015/06/30/%E7%B5%8C%E5%96%B6%E8%80%85-%E7%B7%A8%E9%9B%86%E9%95%B7%E3%82%A4%E3%83%B3%E3%82%BF%E3%83%93%E3%83%A5%E3%83%BC-%E7%B4%B0%E9%87%8E%E6%98%AD%E9%9B%84-%E3%82%A2%E3%82%A4-%E3%82%AA%E3%83%BC-%E3%83%87%E3%83%BC%E3%82%BF%E6%A9%9F%E5%99%A8%E7%A4%BE%E9%95%B7-%EF%BC%92%EF%BC%90%EF%BC%91%EF%BC%95%E5%B9%B4%EF%BC%96%E6%9C%88%EF%BC%93%EF%BC%90%E6%97%A5%E5%8F%B7/, https://www.advertimes.com/20150730/article199139/2/, https://www.nikkan-gendai.com/articles/view/life/159699, http://ascii.jp/elem/000/001/433/1433742/, http://pc.watch.impress.co.jp/docs/column/executive_dinner/1032660.html, http://internet.watch.impress.co.jp/docs/news/698060.html, http://www.itmedia.co.jp/pcuser/articles/1505/25/news002.html, http://www.stereosound.co.jp/news/article/2016/02/17/44212.html, http://mainichi.jp/articles/20161115/gnw/00m/040/005000c, http://itpro.nikkeibp.co.jp/atcl/news/16/110203247/?rt=nocnt, http://itpro.nikkeibp.co.jp/atcl/news/17/062801790/, http://itpro.nikkeibp.co.jp/atcl/news/17/062801790/, http://itpro.nikkeibp.co.jp/atcl/news/17/051701431/, http://www.excite.co.jp/News/market/20170626/Fisco_00093500_20170626_009.html, etc
