Tsugio, of Japanese origin, is derived from two kanji characters: 'Tsugu' meaning 'to continue' and 'Yo' meaning 'having'. Therefore, the name Tsugio translates to 'continuous existence', implying endurance and longevity. It is a unisex name but is more commonly given to boys. Tsugio is pronounced as 'TSU-gi-oh', with the emphasis on the first syllable.
"Tsugio experienced a steady increase in popularity during the early to mid-1920s, peaking at 13 births in 1920 and again at 12 births in 1922. However, it declined significantly afterwards, with only 5 births recorded in 1931."
