How Japanese Names Work: Name Order, Kanji, and Naming Conventions

Japanese names may look simple at first: a family name, a given name, and usually two to four kanji. In practice, however, a single name can raise several questions. Which part comes first? Why can the same kanji have different readings? Should you call someone by their first name, family name, or family name plus -san?

This guide explains how Japanese names work, including Japanese name order, common naming conventions, kanji readings, honorifics, marriage, and the rules used when naming a child.

Japanese name order: family name first, given name second

The standard Japanese order is:

This order is used in Japanese conversation, school records, newspapers, official documents, and most Japanese-language media. It reflects the traditional structure of identifying the family or household before the individual.

Why do some Japanese names appear in Western order?

For many years, Japanese people often reversed their names in English and wrote the given name first—for example, Haruto Tanaka. This custom became established partly because Japanese names were adapted to Western conventions.

Japanese language policy has increasingly recommended preserving the native order in roman letters. Cultural Affairs guidance states that Japanese names are preferably written surname-first in romanization, with capitalization or a comma available when clarification is needed—for example, TANAKA Haruto or Tanaka, Haruto.

In real life, you should follow the form that the person uses on their passport, email signature, publication, or business card. A name is not a grammar exercise; it belongs to the person.

The two main parts of a Japanese name

1. Family name: 姓, 氏, or 名字

Japanese has several words for “surname”:

• 名字／苗字 (myōji): the everyday word for family name
• 姓 (sei): surname, often used in forms and linguistic explanations
• 氏 (shi): the legal term used for a family name in family-law contexts

Common family names include 佐藤 (Satō), 鈴木 (Suzuki), 高橋 (Takahashi), 田中 (Tanaka), and 山本 (Yamamoto).

2. Given name: 名 or 下の名前

The given name is called 名 (na) in formal language or 下の名前 (shita no namae, “the lower/second name”) in everyday speech. Examples include Haruto, Yui, Ren, Aoi, and Sakura.

Japanese people do not normally use a middle name in the domestic Japanese naming system. People with multinational backgrounds may have additional names, but those names do not always fit neatly into standard Japanese forms.

Why Japanese names are difficult to read

A Japanese name is not always pronounced according to the most common textbook reading of its kanji. The same character can have multiple readings, and parents may combine characters and sounds in different ways.

The exact reading is therefore part of the name itself. Even native Japanese speakers sometimes ask:

お名前は何とお読みしますか。
Onamae wa nan to oyomi shimasu ka?
“How is your name read?”

Since May 26, 2025, the pronunciation of names has been added to Japan’s family register system. The revised rules require newly registered readings to be generally recognized as readings of the characters used in the name. This does not make every name predictable, but it formally records the reading.

Kanji, hiragana, and katakana in Japanese names

Japanese names may be written in:

• Kanji: the most common choice, carrying visual and semantic associations
• Hiragana: often creates a soft, simple, or traditional impression
• Katakana: less common for Japanese given names, but used in some personal names and frequently for foreign names

For example, the name Sakura could be written as 桜, さくら, or with a different kanji combination chosen for the same or a similar reading. These spellings are not interchangeable on official documents.

How Japanese people address one another

Knowing the parts of a name is only half the problem. You also need to know which part to say.

Calling a new adult acquaintance by their given name without an honorific may sound unusually intimate. A reliable beginner rule is: use the family name plus -san until the person suggests something else.

What happens to surnames after marriage?

Under Japan’s current civil and family-register system, a married Japanese couple generally chooses one shared legal surname. The selected surname may be the husband’s or the wife’s, although in practice one pattern has historically been much more common.

People may also continue using a former surname professionally or have it shown alongside a current surname in some official and workplace contexts. Legal surname, professional name, stage name, and online name can therefore differ.

How parents choose Japanese baby names

Parents commonly consider several elements at once:

• the sound and rhythm of the name
• the meanings and images associated with the kanji
• how the characters look with the family name
• stroke-count traditions or family preferences
• whether the reading is easy to understand
• seasonal, natural, moral, or aspirational imagery

Japanese law does not allow every possible kanji in a child’s registered name. Names may use hiragana, katakana, and kanji from the legally permitted sets, which include the jōyō kanji and additional jinmeiyō kanji approved for personal names.

How to introduce a Japanese name naturally

田中陽翔です。たなか はるとです。
Tanaka Haruto desu. Tanaka Haruto desu.
“I’m Haruto Tanaka.”

In Japanese, a person normally gives the family name first. In an international setting, they may reverse it or clarify:

My name is Haruto Tanaka—Haruto is my given name.

Frequently asked questions

Do Japanese names always put the surname first?

In Japanese contexts, usually yes. In English contexts, both orders are encountered. Follow the individual’s own usage and official documents.

Do Japanese people have middle names?

The standard domestic naming pattern does not include a middle name. Multinational families and foreign residents may use more complex name structures.

Why do Japanese people use family names so often?

Family-name address maintains social distance and identifies a person within a group. Given-name use often suggests greater closeness, although workplaces and social groups differ.

Can two people have the same kanji name but different pronunciations?

Yes. A kanji or kanji combination can have multiple name readings. The registered or personally stated reading determines the pronunciation.

Should I write Shinzo Abe or Abe Shinzo?

Both have appeared historically in English. Surname-first reflects Japanese order, while the person’s established English usage and the style guide of the publication should also be respected.
