JIS X 0201, a Japanese Industrial Standard developed in 1969 (then called JIS C 6220 until the JIS category reform), was the first Japanese character encoding to become widely used. It is either 7-bit encoding or 8-bit encoding, although 8-bit encoding is dominant for modern use. The name of this standard is 7-bit and 8-bit coded character sets for information interchange (7ビット及び8ビットの情報交換用符号化文字集合).

For 7-bit encoding, it is 128 potential codes where two 96 graphic character sets selected with Shift Out and Shift In characters. For 8-bit encoding, it yields 256 potential codes combining two graphic character sets. The first 96 codes comprise a Japanese variant of ISO 646, or ASCII with backslash (\) and tilde (~) replaced by yen (¥) and overline (‾), while the second 96 codes consist mainly of katakana. Control characters are specified in JIS X 0211. Note that this standard does not define any means to encode kanji.

JIS X 0201 was supplanted by subsequent encodings such as Shift JIS (which combines this standard and JIS X 0208) and later Unicode.

The substitution of the yen symbol for backslash can make paths on DOS and Windows-based computers with Japanese support display strangely, like "C:¥Program Files¥", for example. Another similar problem is C programming language's control characters of string literals, like printf("Hello, world.¥n");.
