How to Name a Japanese Character in Your Story: Era, Region, Realism

Surname first, given name second

A Japanese name has two parts: the surname, myōji, which comes first, and the given name, shita no namae, the lower name, which comes second. There are no middle names for most Japanese people. In Japanese text the full name is written surname first without a space or with a small space: 田中和子 or 田中 和子.

Inside your story, think about which part of the name each character will use. Narrators often use the surname for adults and the given name for children and close friends, and that choice tells the reader a lot about the relationship.

Myōji is written both 名字 and 苗字, and both are correct. On formal documents the full name is shimei (氏名).

Four characters, four eras

The fastest way to make a character feel real is to match the given name to the birth year. These four imaginary people show the shift over about a century. A Japanese reader would place each one in an era at a glance.

Treat the table as a feel, not a rule: every era has exceptions, and families with strong traditions keep old names. But if your 1950s housewife is called Himari, a Japanese reader will notice.

Surnames: common, regional and rare

Most Japanese surnames are built from landscape words, field, mountain, river, tree, village, which is why so many contain 田, 山, 川, 木 or 村. A handful of surnames are extremely common nationwide, and using them makes a character feel ordinary in a good way. For a minor character, an ordinary surname is almost always the right choice.

Some surnames suggest a region. Okinawa is the clearest case: surnames such as Higa, Kinjō and Ōshiro are especially common there, and a character with one of them will read as having Okinawan roots. Other regions have their typical surnames too, but the patterns are subtler; if regional realism matters, look up which surnames are common in your setting.

Notice the last two. Surnames like Ichinose and Kanzaki are real, but they appear so often for heroes and rivals in manga and games that some Japanese readers find them a little dramatic. Rare surnames can be fun for a main character; a whole cast of them feels like a fantasy.

The checks Japanese parents make, and you should too

Your character's parents would have checked a few things before choosing the name, and checking the same things yourself makes the name believable. Say the full name aloud, surname plus given name, and listen to the rhythm. Avoid accidental words: some sound combinations make a joke or an unfortunate word together with the surname. Check the name is not a well-known real person, especially a celebrity or a historical figure, unless you mean it.

Think about what the parents wished for. A name expresses a wish, and a character who knows their name's meaning has something to say about it. Japanese has two lovely expressions for the relationship between a name and a person.

Namaemake is a gentle, often joking word. A boy called Tsuyoshi (strong) who is scared of dogs is a classic case, and a character can tease another with it, or worry about it themselves. Na wa tai o arawasu is the opposite idea: the name fits the person perfectly.

How characters call each other

In Japanese stories, forms of address carry the relationship. Coworkers who are not close use the surname with -san. Childhood friends may use the given name bare, or a nickname. Girls are often called -chan by friends and family, boys -kun, though both are used flexibly. Nicknames are usually built from the first two syllables of the name plus -chan, or a doubled sound, as in Takkun for Takuya.

The moment one character starts using another's given name is a classic turning point in Japanese stories. Shita no namae de yonde mo ii?, can I call you by your first name?, is a line readers recognise.

Mini dialogue: a new transfer student

A short scene that shows how names and address work together. A transfer student introduces herself; a classmate tries a nickname.

Foreign and mixed-heritage characters

A character with a non-Japanese parent may have a Japanese surname and a given name that works in two languages, such as Emma or Ken, written in katakana or with kanji chosen for the sound. A foreign character living in Japan writes their name in katakana, and Japanese characters will usually call them by surname with -san at work and by given name among friends, often because the surname is harder to say.

Foreign names in katakana are usually kept in their own order, given name first, with a middle dot between the parts. That small detail shows care for realism.

Workshop your cast with Mocchi

Tell Mocchi about your story: "I'm writing a novel set in 1960s Osaka. Suggest names for a shopkeeper born in 1915, his daughter born in 1940 and her son born in 1962, and explain each choice." Mocchi suggests names with kanji and readings, explains why each fits, and remembers your story, so next time you can pick up the same cast.

Then send a few lines of dialogue with /correct to check that forms of address sound natural. To hear them, ask Sakura-sensei in AI Sensei to play one of your characters while you play another.

Mistakes that break a Japanese name's realism

• Mixing name orders in the same text. Choose surname-first or given-name-first and keep it.
• Giving an older character a name from today. A grandmother called Himari or a 1950s salaryman called Haruto will jar Japanese readers.
• Filling the cast with rare or dramatic surnames. Most people around your hero should be ordinary Tanakas, Satōs and Suzukis.
• Writing -san in the narration for everyone. Narrators usually drop honorifics; characters use them in dialogue.
• Using a famous real person's full name by accident. Search the name before you commit to it.
• Choosing kanji for meaning alone and never checking the reading. If you are unsure how a name is read, the reader will be too.
