The surname Hirai (平) is a Japanese surname that comes from the Japanese system of hereditary surnames, known as "sei". The character "Hirai" consists of two kanji characters, "Hi" (平) and "Rai" (頼).
The character "Hi" means 'flat' or 'level', while "Rai" can mean 'reliance upon', 'trust in', or 'dependence on'. The name Hirai therefore broadly signifies a place that is flat, level ground one trusts or depends on.
In Japanese history, many families took their surname from the location where they lived, or the occupation of the family's ancestors. In this case, it is possible that the original bearer of the Hirai name lived in an area characterized by flat, level ground and relied on that land for their livelihood.
However, it's important to note that the specific origin of a Japanese surname can be difficult to trace due to the long history of Japan and the lack of written records before the Heian period (794-1185). Therefore, the above explanation is a general interpretation and not an exact account of the origin of the Hirai surname.

The meaning and origin of the last name Hirai
The surname Hirai is of Japanese origin, specifically from the Ryukyu Kingdom (now Okinawa, Japan). It is written as平 in Japanese Kanji characters, which can be translated literally as "flat" or "level."

Today, the Hirai family name is found across Japan and in various immigrant communities around the world.

It is written using different kanji characters in various regions, reflecting its long history within the island nation. One possible interpretation of the name "Hirai" includes the characters for "plow field" or "wide rice field," suggesting a connection to agriculture in ancient times.
Historical records show that the Hirai family traces their lineage back to the Heian Period (794-1185 AD), when Japan was under the rule of Emperor Kanmu. During this era, many noble families established themselves throughout the country, and some scholars believe the Hirai family might have descended from these noble houses.
The family gained prominence in feudal Japan during the Edo Period (1603-1867 AD), where they held important positions within the imperial court or served as regional samurai lords. Some branches of the Hirai family migrated to Hawaii during the late 19th and early 20th centuries, where their descendants continue to live today.
