In Japan, [[mobile phones]] became ubiquitous years before the phenomenon spread worldwide. In Japanese, mobile phones are called {{nihongo|''keitai denwa''|携帯電話}}, literally "portable [[telephones]]," and are often known simply as ''keitai'' (携帯).
==Market==
{{As of|2013}}, the Japanese mobile phone market is broadly divided into a high-end, consisting of [[smartphones]] ({{nihongo|スマートフォン|sumātofon}}, abbreviated as {{nihongo|スマフォ|sumafo}} or {{nihongo|スマホ|sumaho}}); mid-range, consisting of [[feature phone]]s ({{transltransliteration|ja|garakei}}); and a low-end, consisting of [[Personal Handy-phone System]] (PHS, {{nihongo|handy phone|ハンディフォン|handifon}} or {{nihongo||ピッチ|pitchi}}, from {{nihongo|PHS|ピーエッチエス|pīetchiesu}}). There is some overlap of market segments between low-end smartphones and high-end feature phones, and many shared features. PHS, which was initially developed as a cheaper alternative to 2G networks such as CDMA and [[GSM]], was initially deployed in 1995, but is now only offered by one carrier, [[Y!Mobile]] (part of [[SoftBank Group|SoftBank]]). As elsewhere in the world, smartphones have been growing rapidly.{{fact|date=October 2023}}
==In use==
The use of mobile phones to make calls on public transport is frowned upon, and messages asking passengers not to make calls and to switch their phones to silent mode ("public mode" or "manner mode" in Japanese) are played frequently. This, combined with the low per-message price and ample allowed length per message (10,000 characters), has increased the use of text messaging as an alternative to calls. Abbreviations are also widespread. '\' may be attached at the end of a sentence to show that they are not happy about the event described. A sentence like "I have a test today\" (translated) could be used to imply that the student didn'tdid not study enough, or that the test itself invites [[negative emotion]]. Some of these usages disappeared as suitable [[emoji]] were made, but these newly made icons also acquired a usage not originally intended. One example deals with the astrological symbol for [[Libra (astrology)|Libra]] (♎). It resembles a cooked and puffed [[Mochi (food)|mochi]], and is sometimes used in a happyHappy newNew yearYear's message as mochi are often eaten then. The symbol for [[Aquarius (astrology)|Aquarius]] (♒) resembles waves, so this would be used to mean 'sea'. The number of icons gradually increased and they are now coloured on most cell phones, to make them more distinct. [[ASCII art]] is also used widely and many of them are faces with expressionexpressions. ''(see also [[Shift JIS art]])''

A '''cell phone novel''', or {{nihongo|'''mobile phone novel'''|携帯小説|keitai shōsetsu|{{zh|t=手機小說|p=shǒujī xiǎoshuō}}|lead=yes}}, is a [[literary]] work originally written on a [[cellular phone]] via [[text messaging]]. This type of [[literature]] originated in Japan, where it has become a popular [[literary genre]]. However, its popularity has also spread to other [[countries]] internationally, especially to [[China]], the [[United States]], [[Germany]], and [[South Africa]]. Chapters usually consist of about 70–100 words each due to character limitations on cell phones.<ref name="Asahi News">{{Cite web |date=2007-02-11 |title=普通の若者が携帯小説 ベストセラーも続々 |trans-title=Ordinary young people are mobile novels, bestsellers one after another |url=http://book.asahi.com/clip/TKY200702100253.html |url-status=dead |archive-url=https://web.archive.org/web/20121021181206/http://book.asahi.com/clip/TKY200702100253.html |archive-date=2012-10-21 |access-date=2009-11-05 |website=book.asahi.com}}</ref>

==Decoration==
[[File:703shf3.jpg|thumb|Japanese cell phones are often decorated, as in this example.]]
Phone decorations are common, notably [[mobile phone charms]] and various stickers. The stickers are often in the [[maki-e]] style, and are advertised as such.
* ''8-8-9-1-9'' – ha-ya-ku-i-ku ("hurry up, let's go")
With the rapidly falling prices of cell phones in the mid -1990s, young people began experimenting with the [[SMS|short message service]] that the mobile phone companies started offering. When the [[i-mode]] service became available, the mobile phone culture began flourishing earnestly as this service offered an E-mail application. Magazines and television regularly make specials focusing on the current trend of how mobile phones are used by young people.
