Character Names & What they Mean

Serena Tsukino Usagi (Tsukino Usagi) Sera Muun (Sailor Moon)
Amy Mizuno Ami (Mizuno Ami) Sera Maakyuri (Sailor Mercury)
Raye Hino Rei (Hino Rei) Sera Masu (Sailor Mars)
Lita Kino Makoto (Kino Makoto) Sera Jupitaa (Sailor Jupiter)
Mina Aino Minako (Aino Minako) Sera Biinasu (Sailor Venus)

tsuki means "moon" and usagi means rabbit.  These words are a reference to the Japanese custom of seeing the shape of a rabbit in the face of the full moon.  In fact if you write out Serena's Japanese name tsuki no usagi using a different Japanese symbol for the no sound, it would mean "rabbit of the moon".  According to this legend, the rabbit lives on the moon and makes mochi (a sticky treat made by pounding sweet rice).  In the modern Japanese calender tsuki is also the symbol for Monday.

mizu or sui means "water".  sei means star or heavenly body.  suisei is the Japanese name for the planet Mercury. This symbol also means Tuesday.

hi or ka means "fire".  kasei means the planet Mars. This symbol also means Wednesday.

ki or moku means "tree".  mokusei means the planet Jupiter. This symbol also means Thursday.

  ai means "love".  mi or bi means "beautiful".  The name for the planet Venus in Japanese is kinsei (kin means "gold" and is also the symbol for Friday).  However, because Japanese symbols (kanji) can have more than one pronunciation, mi-na-ko can also be read as bi-na-subinasu is how Japanese would pronounce the word "Venus".

Sera (Sailor) is written phonetically.  These Japanese symbols are called katakana and they have no meaning except for their sound.  The Sailor Identities always use English planet names.

Furigana is mostly used in children's books; adults are expected to know the kanji from memory. However furigana is also used to specify the reading when kanji is used in an unusual or uncommon way.

The girl's names, birthdays, zodiac signs, personalities, and special powers are all related to the planet that they are the soldier of.  In ancient Roman mythology, Mercury was associated with science and commerce, Mars with war, Jupiter with thunder and lightning, and Venus with love. In ancient Japanese tradition there were considered to be five elements: air, water, fire, wood, and metal. The colors (white, blue, red, brown/green, and gold) and to some degree the superpowers of the girls correspond to these five elements.

How people are addressed in Japanese

Here is some vocabulary that you are likely to come across when reading about Japanese stories.

In Japanese and Chinese, the family name is written first and the given name is written second.  Japanese people don't usually have middle names.  Japanese names are almost always used with a title.  The title is a suffix like -san or -chan-san basically means Mr./Mrs./Miss/Ms.  Surnames (family names) are always used except when talking to personal friends or family.

Politeness Suffix Examples
Most Polite -sama The villians call Beryl, Queen Beryl-sama.  Sailor Moon calls Tuxedo Mask Tuxedo Kamen-sama.
Professionals -sensei Used for teachers, doctors, or anyone who is an expert or leader in their field.  Miss Haruna the schoolteacher is called Haruna-sensei or just Sensei.
Normal Politeness -san The "default" suffix for most situations.
Senior Students -senpai Title for an older schoolmate.  It implies someone you look up to or whose example you follow.  Although it's a formal term, it's also used amongst friends.  Sometimes used by girls even to address their own boyfriends if that boyfriend is in an upper grade.  Makoto (Lita) calls her "old boyfriend" senpai.
Less formal -kun Used to address a male who is a friend, or to address someone junior to yourself in a workplace/business setting.
Least Formal -chan A cute suffix indicating a close friendly relationship.  Usually, but not exclusively, used for girl's names.  In Sailor Moon, the girls call each other Usagi-chan, Mako-chan, Ami-chan, etc.
Pet Names -chan When they are together Usagi calls Mamoru Mamo-chan.  -chan can be used for anything cute like children, babies, or pets.
Pet Names -ko Mamoru calls Usagi Usako (-ko is a feminine ending)

Note: Not using any suffix indicates a close relationship which could include family, childhood friends, or adult lovers.  Sensei and Senpai can be used by themselves or as a suffix added to someone's name.
