Japanese Mobile Phone Culture
Japanese mobile phone culture is a unique and fascinating phenomenon. Pagers, also known as beepers, were the precursors to mobile phones and were widely used by teenagers in the late 1980s and early 1990s.
These early pagers could only display numbers, but teenagers quickly found creative ways to use them to communicate with each other. They developed numeric messages that could be read in Japanese, such as "4-6-4-9" which means "hello" or "best regards".
Teenagers used these numeric messages to express everyday emotions and greetings. For example, "3-3-4-1" means "I feel lonely" and "8-8-9-1-9" means "hurry up, let's go".
The popularity of mobile phones among teenagers grew rapidly in the mid-1990s as prices fell. With the introduction of short message service (SMS), young people began experimenting with sending text messages to each other.
Here are some examples of numeric messages used by teenagers in Japan:
- 4-6-4-9 – yo-ro-shi-ku ("hello", "best regards")
- 3-3-4-1 – sa-mi-shi-i ("I feel lonely")
- 8-8-9-1-9 – ha-ya-ku-i-ku ("hurry up, let's go")
Mobile Phone Use in Japan
Mobile phones have been a staple in Japan for decades, with a unique culture surrounding their use. Pagers, which predated mobile phones, were used by teenagers in the late 1980s and early 1990s to communicate with each other.
Teenagers were creative in using numeric messages to convey emotions and greetings, often based on ways numbers could be read in Japanese. For example, the number 4-6-4-9 could mean "hello" or "best regards", while 3-3-4-1 could mean "I feel lonely".
The rise of mobile phones in the mid-1990s led to the popularity of short message service (SMS) and email applications, with the i-mode service being a significant contributor to the flourishing mobile phone culture.
Japanese culture places a strong emphasis on public etiquette, which extends to mobile phone use. To avoid being annoying to others, many people put their phones in "manner mode" to silence the ringtone, and it's considered rude to answer a cell phone in certain public places, such as on a train.

Teenagers and Phones
Teenagers and phones have a special history in Japan, dating back to the late 1980s when paging devices first became popular among young people. These early devices could only display numbers, but teens quickly found creative ways to use them, such as numeric messages that could be read in Japanese.
For example, the number 4-6-4-9 was used to say "hello" or "best regards", while 3-3-4-1 meant "I feel lonely". The number 8-8-9-1-9 was used to say "hurry up, let's go".
As mobile phones became more affordable in the mid-1990s, young people began experimenting with short message service (SMS). The i-mode service, which offered an email application, further fueled the growth of mobile phone culture among teenagers.
It's still considered impolite to answer a cell phone in certain public places, such as on the train. However, writing emails or playing games on a cell phone while on the train has become a normal part of Japanese culture.

Unique Features of Japanese Phones
Japanese phones are renowned for their advanced features, many of which are unique to the country. Japan was a leader in mobile phone technology, with the first commercial camera phone, the Kyocera Visual Phone VP-210, released in May 1999.
Some of the notable features of Japanese phones include email, configurable databases, phone and address books, and alarm clocks and stopwatches. Many phones also come with live video feed via Piconet, mobile games, and image enhancement capabilities.
Here are some of the advanced features found in many Japanese phones:
- E-money service and various certification functions through Untouched IC card (FeliCa etc.)
- Various services with NTT DoCoMo’s ‘Osaifu-Keitai (mobile phone with wallet function)’
- E-money service e.g. ‘Edy’
- Function as ‘Mobile Suica,’ which can be used for a season ticket and a train ticket
- Cmode: vending machines which can be used with QR Code and ‘Osaifu-Keitai’ of a mobile phone
These features have led to the term "Galápagos syndrome", as these resulting phones were dominant in Japan but unsuccessful abroad.

Gyaru Moji
Gyaru Moji is a unique form of writing used by some Japanese phone users.
It involves replacing Latin characters with hiragana or katakana, making it difficult to decipher the original message. For example, the letter 'L' and 't' are replaced with the hiragana character け ('ke'), which looks similar when written.
This style of writing is often used to hide the meaning of words or to extend the length of a message due to character limits. Japanese phones have a character limit of 160 Latin characters, but only 70 Unicode characters, including kanji.
Gyaru Moji is similar to the 1337 language used in English hacking culture, where characters are replaced with similar-looking alphanumeric characters to conceal meaning. This unique writing style has become a distinct feature of Japanese phone culture.

Mobile Phone Technology in Japan
Mobile phone technology in Japan is incredibly advanced, with a popular trend of using special barcodes called QR codes to read information from mobile phone handsets.
These QR codes are a form of 2D barcode that can be scanned using a phone's camera or other input, and can contain links to web site addresses, email addresses, or even address and telephone numbers.
All over Japan, you can find posters with QR codes on them, as well as in magazines and even on some people's business cards.
Sony, working with NTT DoCoMo, has been spearheading the mobile phone wallet technology, commonly known as 'FeliCa', which uses an RFID chip inside the handset to communicate with reading devices.
This technology allows users to pay for goods using their phones at convenience stores and even some vending machines, by 'charging up' their accounts with credits beforehand.
Some locations in Japan are now using mobile phones as a purchase system for virtual shops and smart shops, and even as an authentication system in the medical field.
Gracenote and Media Socket have a service where users can hold their phone up to a source of music and, by dialing a certain phone number, find the song in a database and have it identified within seconds.
Users can then use this information to search the mobile internet to find that song.
Mobile Phone Etiquette in Japan
Mobile phone etiquette in Japan is a crucial aspect of communication, and it's essential to adhere to certain rules to show respect to the person on the other end of the line.
In Japan, it's customary to answer the phone with "moshi moshi", a common greeting used when answering the phone and a sign of respect. Introducing yourself on the phone is also important, stating your name and the organisation you represent when answering the phone.
To be respectful, it's best to find a quiet location to take the call, as making noise while on the phone is considered impolite. Avoid eating, chewing gum, or typing while on the phone, as it can be considered disrespectful.
Here are some key phone etiquette rules to keep in mind:
- Use polite language and address people with their correct titles and honorifics.
- Respect privacy and only ask questions that you know the other person is likely to be comfortable with.
Japanese people generally have excellent phone manners on the train or elsewhere in public, and chatting on the phone on the train is considered extremely rude and generally isn’t tolerated.
People Have Good Manners in Public
Japanese people are generally very considerate of others when using their mobile phones in public. They tend to avoid chatting on the phone on the train, which is considered extremely rude and generally isn't tolerated.
In Japan, it's not uncommon to see people using headphones and holding their phone up to their mouth when making a call, as opposed to walking around talking to themselves like you might see in the US or UK.
Even the Top Gear guys got told off for using a phone on the Shinkansen during one episode, highlighting the importance of keeping mobile phone use to a minimum in public.
You can often spot Japanese people using their mobile phones in public, but they usually do so in a way that doesn't disturb others. They might be watching a video or playing a game, but they'll often be using headphones to keep the noise to a minimum.
Here are some key takeaways for mobile phone etiquette in public in Japan:
- Be mindful of your surroundings and avoid making noise on your phone.
- Use headphones or earbuds to keep the noise to a minimum.
- Be considerate of others and avoid using your phone in crowded areas or on public transportation.
By following these simple rules, you can blend in with the locals and avoid drawing attention to yourself.
Emoji
Emoji is a big part of mobile phone culture in Japan, and it's been around since 1997. The first phone to support a set of emojis was the SkyWalker DP-211SW, manufactured by J-Phone.
These early emojis were intended to help facilitate electronic communication and serve as a distinguishing feature from other services. Shigetaka Kurita created a highly influential set of 176 cellular emojis in 1999 for NTT DoCoMo's i-mode.
The Face with Tears of Joy emoji, which is now widely used worldwide, was part of this original set and represents a Japanese visual style commonly found in manga and anime. Kurita took inspiration from Japanese manga and weather pictograms when designing these emojis.
Taking a Bath
Taking a bath is a big part of Japanese culture, with many people indulging in hot dips at traditional onsen, sento, or private family baths.
In Japan, baths are a common place to relax and unwind, but they can also pose a problem for mobile phone users. You're faced with a tough decision: take a short bath and quickly get back to the internet, or risk your phone to its steamy depths.
This dilemma has led to a huge market for waterproof phones in Japan, with almost every manufacturer offering waterproofing on most of their models. You'll often see advertisements with models using their phone in the bath to highlight just how waterproof they are.
Bath time is a unique opportunity to try out your waterproof phone, but be sure to check the manufacturer's guidelines for proper use and maintenance.

Mobile Phone Market in Japan
The Japanese mobile phone market is a unique beast, with a clear division between high-end, mid-range, and low-end options. As of 2013, the market is broadly divided into these three segments.
Smartphones are the high-end option, with many Japanese consumers opting for these devices due to their advanced features and capabilities. In fact, smartphones have been growing rapidly in Japan, much like elsewhere in the world.

Market
The Japanese mobile phone market is divided into three main segments: high-end, mid-range, and low-end. The high-end segment consists of smartphones, which have been growing rapidly.
Smartphones in Japan are known as スマホ (sumaho) or スマフォ (sumafo), and they're extremely popular. In fact, Japan is the single largest market for mobile gaming in the world.
The mid-range segment consists of feature phones, also known as garakei. These phones are a great option for those who don't need the latest smartphone features but still want a reliable phone. With the prevalence of incredibly fast internet, even feature phones can offer a good gaming experience.
The low-end segment consists of Personal Handy-phone System (PHS) phones, also known as handy phone (ハンディフォン, handifon) or pitchi (ピッチ). PHS phones were initially developed as a cheaper alternative to 2G networks and were first deployed in 1995. Today, only one carrier, Y!Mobile (part of SoftBank), offers PHS phones.
Here's a brief overview of the Japanese mobile phone market:

The Japanese market is the largest for mobile games, generating $5.1 billion in 2013, more than traditional console games in the country.
Many adults in Japan play smartphone games, often during their long train commutes, making it a convenient way to pass the time.
The assumption that only kids play video games is narrow-minded, especially in a country with a huge industry built around smartphone games.
You'll notice plenty of adults of both genders playing handheld consoles on the train, too, showing that gaming is not just for kids.
Japan's compact living spaces mean that many people don't have room for gaming consoles or PCs, making their phones their primary source of entertainment.
Selfie Culture
Selfie culture has its roots in Japanese kawaii culture, which emphasizes beautifying self-representation in photographs.
The obsession with self-photography began among Japanese schoolgirls in the 1990s, who would take photos with friends and exchange copies to paste into kawaii albums.

Purikura, a Japanese photo sticker booth phenomenon, emerged in the 1990s and became a popular form of entertainment among youths in Japan and East Asia.
The first purikura was introduced by Sega and Atlus in February 1995, initially at game arcades and later expanding to other locations.
Japanese mobile phones began including front-facing cameras to capitalize on the purikura phenomenon, with the Kyocera Visual Phone VP-210 being the first front-facing camera phone, released in Japan in May 1999.
This phone could store up to 20 JPEG images, which could be sent over e-mail or sent over Japan's Personal Handy-phone System (PHS) wireless cellular network at a rate of up to two images per second.
Photographic features from purikura and smartphones were later adopted by apps like Instagram and Snapchat, allowing users to add features like graffiti, text, and photo editing options.

Sony is a particularly popular choice due to its Japanese roots, which gives it a natural edge in terms of popularity. Huawei phones are also widely available and sought after for their affordability and quality.
Interestingly, Samsung isn't as well-represented in Japan, largely due to historical tensions between Japan and South Korea. This has even led Samsung to rebrand itself as Galaxy for the Japanese market.
