Meaning
The kanji 后 (コウ, きさき) primarily means an empress, a queen, or a sovereign ruler. It specifically refers to a female monarch or the consort of an emperor or king. While in historical Chinese usage it could also imply 'behind' or 'after' (similar to 後), in modern Japanese, 后 is almost exclusively used for royalty and imperial positions, particularly for women.
Its etymology is ancient and somewhat debated, but common interpretations link it to a figure of authority. Some theories suggest it depicts a person giving orders or a figure with a distinctive head covering signifying leadership. The top part (丆) is sometimes related to 'command' or 'direction'. Meanwhile, the bottom part (卩) can represent a 'kneeling person' or a 'seal', suggesting reverence or power. Over time, it simplified and evolved. It's also seen as a variant of kanji like 司 (manage) or 嗣 (succeed), reinforcing the idea of leadership and succession. Though simplified to its current form, its essence as a symbol of supreme female authority remains.
This 6-stroke kanji is a Joyo kanji. However, it is not taught in standard elementary school grades (1-6) and is typically learned at higher levels or within specific historical/literary contexts. It is designated as an N1 level kanji in the JLPT system, reflecting its specialized usage.

Memory Tip
To remember 后, think of its meaning as 'empress' or 'queen'. Visually, imagine the top part of the kanji (丆) as a stylized crown or a commanding gesture, symbolizing authority and leadership. The bottom part (卩) resembles a person kneeling or a seal, suggesting reverence or power. Together, the kanji depicts a figure with a crown or authority who commands respect—the empress. You could also think of the top part as 'one' (一) under a 'roof' or 'cover', and the bottom as a 'seal' (卩), forming the 'one who holds the imperial seal' – the empress.
