Meaning
The kanji 墨 (boku, sumi) primarily means ink. It specifically refers to the traditional solid Chinese ink stick used in East Asian calligraphy and ink wash painting. However, it can also refer to the liquid ink produced from grinding these sticks or generally to any dark, black ink. This meaning is deeply rooted in ancient East Asian writing and art practices.
The visual structure of 墨 offers clear insight into its meaning. It is composed of two main components: 黒 (kuro), meaning “black,” and 土 (tsuchi), meaning “earth” or “soil.” This combination beautifully illustrates the essence of ink production. Traditionally, high-quality ink was made by burning pine soot (a form of black carbon) or oil soot, mixing it with animal glue, and forming it into sticks. Thus, the “black earth” or “black soil” component directly alludes to the dark, carbonaceous material. This material, derived from the earth, forms the basis of black ink. The top part, 黒, establishes the characteristic color, while 土 suggests the raw material or solid form from which the ink is produced.
The kanji 墨 has a total of 15 strokes. As an N1-level kanji, it is considered advanced and is not taught in elementary school (grade 0).

Memory Tip
To remember the kanji 墨, simply think of "black earth." The kanji is composed of 黒 (kuro), meaning "black," and 土 (tsuchi), meaning "earth" or "soil." Imagine traditional ink sticks are literally made from the black remnants of burnt pine or oil—byproducts of the earth. So, when you see 墨, picture black (黒) earth (土), processed to create the rich, dark pigment we know as ink. This visual story connects the components directly to the meaning, helping you recall that 墨 refers to ink, especially ink derived from natural, black earth materials.
