Meaning
Today, we're exploring the N1 kanji 浄 (じょう), a character that signifies 'cleanliness' and 'purity.' While it shares some meaning with the more common kanji 清, 浄 often carries a stronger nuance of 'purification' or 'cleansing.' It frequently appears in contexts related to spiritual, ritualistic, or mechanical purification processes. It’s not just about being clean, but about the act or state of becoming clean, often from impurities or defilement.
Consider its visual components. The left side of 浄 is the familiar water radical (氵, さんずい), which, as you might guess, immediately hints at a connection to water, liquids, or washing. This is a common pattern in kanji related to cleanliness. The right side is 争 (あらそう), meaning 'to contend,' 'to dispute,' or 'to struggle.' This might seem a bit odd for 'purity' at first glance. However, in this context, 争 acts as both a phonetic component (guiding the sound) and a semantic hint. Think of it as water (氵) actively 'struggling' or 'striving' to remove impurities, to clear away dirt, or to achieve a state of perfect cleanliness. It represents the effort involved in purifying something—the active process of making something pristine. This kanji perfectly captures the essence of active cleansing or achieving a refined state.
This kanji has 9 strokes and is considered a grade 8 kanji. This means it's part of the extended set of Jōyō kanji (Supplemental Joyo) learned by advanced students or in specialized contexts, aligning perfectly with its JLPT N1 classification.
Readings
On'yomi (音読み) — Chinese-derived readings
The primary On'yomi for 浄 is ジョウ (JŌ). This reading is very common in compound words, especially those relating to purification, cleaning systems, or spiritual concepts.
- 浄化 (jōka) — purification, cleansing. This is a frequently used word, applied to purifying water, air, or even one's mind. For example, 空気の浄化 (kūki no jōka) means "air purification."
- 洗浄 (senjō) — washing, cleaning. Often refers to industrial or thorough cleaning, such as 機器の洗浄 (kiki no senjō) for "cleaning machinery."
- 清浄 (seijō) — purity, cleanliness. Often used in a more formal or spiritual context, implying a high degree of cleanliness or sacredness, such as 清浄な空気 (seijō na kūki) for "pure air."
- 浄水 (jōsui) — purified water. You'll often see this on water filters or bottled water, as in 浄水器 (jōsuiki) for "water purifier."
- 浄土 (jōdo) — Pure Land. This term is central to Pure Land Buddhism, referring to the pure land of Amitābha Buddha. An example is 浄土宗 (Jōdo shū), a well-known Buddhist sect.
Kun'yomi (訓読み) — Native Japanese readings
The Kun'yomi for 浄 are きよ.い (kiyo.i), きよ.める (kiyo.meru), and きよ.まる (kiyo.maru). These readings are used when the kanji is part of a native Japanese word, often as a verb or adjective stem. While 清い is more commonly used for general 'clean' or 'clear,' 浄い specifically implies a deeper, often spiritual or moral purity.
- 浄める (kiyomeru) — to purify, to cleanse (transitive verb). This refers to the act of making something pure or clean. For instance, 身を浄める (mi o kiyomeru) means "to purify oneself," often in a ritualistic sense before entering a shrine.
- 浄まる (kiyomaru) — to become pure, to be purified (intransitive verb). This describes a state where something becomes pure on its own or as a result of a process. An example is 心が浄まる (kokoro ga kiyomaru), meaning "one's heart becomes pure."
- 浄い (kiyoi) — pure, clean (adjective). While 清い is more common, 浄い emphasizes a deeper, often spiritual, or untainted purity, as in 浄い心 (kiyoi kokoro) for "a pure heart."

Memory Tip
Here's a simple story to help remember 浄: Imagine a stream of 水 (water) represented by the left radical 氵. This water has to 争 (struggle, contend) with dirt, leaves, and all sorts of impurities. It's working hard, fighting its way through obstacles, constantly moving and swirling—all with the goal of becoming perfectly 浄 (pure) and clean. So, 浄 is simply 'water' (氵) 'struggling' (争) to become 'pure.' This gives you a clear image of active purification!
