Meaning
The kanji 江 (e, kō) primarily means an inlet, bay, creek, or a river. It often describes a natural waterway, such as a smaller arm of a larger body of water. More broadly, it can also refer to a large river itself. Historically, in China, 江 (jiāng) specifically referred to the Yangtze River. In Japan, however, while it can still denote a river, it is very commonly found in words referring to a bay, a cove, or an inlet—a small arm of the sea or a lake extending inland.
Its origin is a phono-semantic compound. The left-hand radical, 氵 (sanzui), is a variant of 水 (mizu), meaning “water.” This component clearly links the kanji's meaning to water. The right-hand component, 工 (kō), primarily serves as a phonetic element, giving it the “kō” sound. One can also playfully imagine it symbolizing “work” or “craft,” representing either nature's erosion carving a channel or human effort constructing a waterway. Therefore, 江 visually represents “water” flowing in a “channeled” or “worked” path.
Although classified as an N1 JLPT kanji, 江 is a relatively simple character with only 6 strokes. In fact, Japanese elementary school students learn it in Grade 3. The N1 classification for JLPT reflects its more specialized usage in place names and specific terms. It's less common in a wide range of everyday, general vocabulary, which means intermediate learners encounter it less frequently.

Memory Tip
To remember 江, consider its two components: 氵 (water radical) and 工 (craft/work). Imagine “water” (氵) that has been “worked” (工) upon. This 'work' could be nature's erosion, shaping a specific channel, inlet, or river, or human engineering creating a waterway. Visualize the 工 shape as a narrow, crafted channel through which water flows. This simple story connects the visual form of the kanji to its meaning: a body of water that follows a defined path, such as an inlet or a river.
