Details

The keyword for 丁 is street. This kanji originally referred to a block or section of a town, essentially a city street or district division. In Japanese addresses, it is used to denote numbered subsections within a neighborhood, functioning much like a block number. It can also carry the meaning of a counter for certain items or convey the sense of an even number or orderly arrangement.
