Natsuko is a beautiful and distinctively Japanese given name, derived from two kanji characters: "Natsu" (夏), meaning summer, and "Ko" (己), which refers to the sixth heavenly stem in the East Asian calendric system. This name holds significant cultural value, as it embodies the warmth and vibrancy of the summer season.
"Natsuko experienced a significant rise in popularity between 1915 and 1925, with a peak of 17 births in 1925. However, it seems to have fallen out of favor afterward, with fewer than 10 births per year from 1926 onwards, except for a brief spike in 1994."
