Editing Hepburn romanization (section)

=== Extended katakana ===
These combinations are used mainly to represent the sounds in words in other languages.

Digraphs with <span style="background:#fc9;">orange</span> backgrounds are the general ones used for loanwords or foreign places or names, and those with <span style="background:#9cf;">blue</span> backgrounds are used for more accurate transliterations of foreign sounds, suggested by the [[Cabinet of Japan]]'s [[Ministry of Education, Culture, Sports, Science and Technology]].<ref>{{cite web|url=http://www.mext.go.jp/b_menu/hakusho/nc/k19910628002/k19910628002.html|title=平成3年6月28日内閣告示第2号:外来語の表記|trans-title=Japanese cabinet order No.2 (June 28, 1991):The notation of loanword|author=Cabinet of Japan|publisher=[[Ministry of Education, Culture, Sports, Science and Technology]]|access-date=May 25, 2011|author-link=Cabinet of Japan|archive-url=https://web.archive.org/web/20190106125953/http://www.mext.go.jp/b_menu/hakusho/nc/k19910628002/k19910628002.html|archive-date=January 6, 2019|url-status=dead}}</ref> Katakana combinations with <span style="background:#eee8aa;">beige</span> backgrounds are suggested by the [[American National Standards Institute]]<ref name="ansi">{{cite web |url=http://www.ab.cyberhome.ne.jp/~kaizu/roomazi/doc/ansiz3911.html |title=米国規格(ANSI Z39.11-1972)―要約 |access-date=February 27, 2016 |archive-date=March 3, 2016 |archive-url=https://web.archive.org/web/20160303215902/http://www.ab.cyberhome.ne.jp/~kaizu/roomazi/doc/ansiz3911.html |url-status=live }}{{self-published source|date=February 2016}}</ref> and the [[BSI Group|British Standards Institution]] as possible uses.<ref name="bs">{{cite web |url=http://www.ab.cyberhome.ne.jp/~kaizu/roomazi/doc/bs4812.html |title=英国規格(BS 4812 : 1972)―要約 |access-date=February 27, 2016 |archive-date=March 3, 2016 |archive-url=https://web.archive.org/web/20160303224521/http://www.ab.cyberhome.ne.jp/~kaizu/roomazi/doc/bs4812.html |url-status=live }}{{self-published source|date=February 2016}}</ref> Ones with <span style="background:#e1a1ff;">purple</span> backgrounds appear on the 1974 version of the Hyōjun-shiki formatting.<ref name="hyouzyunC"/>

* * — The use of {{nihongo2|ウ}} in these two cases to represent ''w'' is rare in modern Japanese except for Internet slang and transcription of the Latin sound {{IPA|[w]}} into katakana. E.g.: [[w:ja:ミネルウァ|ミネル'''ウァ''']] (''Mineru'''wa''''' "[[Minerva]]", from Latin ''MINER'''VA''''' {{IPA|[mɪˈnɛr'''wa''']}}); [[w:ja:ウゥルカーヌス|'''ウゥ'''ルカーヌス]] ('''''Wu'''rukānusu'' "[[Vulcan (mythology)|Vulcan]]", from Latin '''''VV'''LCANVS'', '''''Vu'''lcānus'' {{IPA|['''wʊ'''lˈkaːnʊs]}}). The ''wa''-type of foreign sounds (as in ''watt'' or ''white'') is usually transcribed to ワ (''wa''), while the ''wu''-type (as in ''wood'' or ''woman'') is usually to ウ (''u'') or ウー (''ū'').
* ⁑ — {{nihongo2|ヴ}} has a rarely used [[hiragana]] form in {{nihongo2|ゔ}} that is also ''vu'' in Hepburn romanization systems.
* ⁂ — The characters in {{green|green}} are obsolete in modern Japanese and very rarely used.<ref name="usage1946"/><ref name="usage1986"/>
