A circle centered on a flag draws the eye instantly, which is exactly why so many countries have built their entire design around one. Suns, moons, wheels, and seals all fall into this category, and while the shape is the same across each of these flags, what’s inside that circle tends to carry very different meaning from country to country.
Japan
A plain red disc on white, representing the sun, and giving the country its name, Land of the Rising Sun.
Bangladesh
A red disc set slightly off-center on green, symbolizing the sun rising over the nation and the blood of its 1971 independence struggle.
Palau
A pale gold, off-center full moon on blue, chosen for its association with peace, unity, and traditional Palauan beliefs around the lunar calendar.
Laos
A white disc representing the moon, centered on a wide blue band, standing for unity and the country’s future.
South Korea
The Taegeuk, a red-and-blue circle split in an S-curve, representing balance between opposing forces, surrounded by four black trigrams drawn from the I Ching.
India
The Ashoka Chakra, a navy blue wheel with 24 spokes, centered on the white stripe, representing law, progress, and the wheel of time.

Argentina
The Sun of May, a golden sun with a human face, centered on the white stripe, commemorating the 1810 revolution against Spanish rule.
