Tomio is of Japanese origin and means "sea" or "harbor". It's composed of two kanji characters: 'Tomi' meaning sea, and 'O', a suffix that indicates respect or honorifics. Therefore, Tomio can be interpreted as a name that signifies tranquility, depth, and perhaps a sense of protection or shelter, much like the calm waters of a harbor. It's a unisex name in Japanese culture, but it's more commonly used for males. Tomio is also found among other East Asian communities with significant Japanese influence, such as those in Korea and China, though its popularity may vary. In Western cultures, it remains relatively uncommon, offering uniqueness while still being familiar due to its oceanic inspiration.
The name Tomio was quite popular between 1915 and 1932, with a total of 102 babies named Tomio during this period. There were several years where the name was particularly common, notably in 1924 when it reached its peak with 14 births, and consistently around 5-7 births annually from 1915 to 1932. However, there is a notable gap in the data for the years 1916, 1921, and 1925-1927, which could indicate either a decrease in popularity or missing records during these periods.
