How do Japanese last names work?
The surname comes first: in print, in speech, in the phone book. Tanaka Haruki is Haruki of the Tanaka household, family name leading.
And each family's writing is fixed. The household, not the individual, settles the kanji: one family line, one writing of the name, passed down as-is. Two Tanakas may write the name the same way and share no relation. The convention is about the family unit, not a shared ancestor.
Readings shift, too. The 山 in Yamada and Yamazaki is the same character read two ways, and common kanji carry uncommon readings. Families sometimes hold a private one for generations. The everyday word for the family name is myoji: one name, first position, fixed writing.
What do Japanese last names mean?
Mostly places and terrain: rice fields, mountains, rivers, villages. A surname is a receipt for where a household lived or what it worked, written in kanji compounds. Read the parts and you read the place. Here's the trick worth knowing: four of Japan's commonest surnames (Sato, Ito, Kato, Saito) share the wisteria morpheme 藤 in their endings. That naming fashion swept the aristocratic era and never left. The same grouping runs through the whole list, so the facets below slice the master table by morpheme family.

The given-name side of the system, what the first name's kanji assert, is a different animal: Japanese names and their meanings tables it A to Z.
