The newer JIS X 0213 standard defines an extended variant of Shift_JIS referred to as Shift_JISx0213 (in a previous version of the standard) or Shift_JIS-2004. It is a superset of standard Shift JIS.[15]

In order to represent the allocated rows on both planes of JIS X 0213, Shift_JIS-2004 uses the following method of mapping codepoints.[16]

In the above, is a two-byte Shift_JIS-2004 sequence, is the {{Nihongo|plane|面|men|surface}} number (1 or 2), is the {{Nihongo|row|区|ku|ward}} number (1-94) and is the {{Nihongo|cell|点|ten|point}} number (1-94). The ku and ten numbers are equivalent to and respectively, where is a two-byte JIS sequence referencing a given plane.

The same set of characters can represented by EUC-JIS-2004, the EUC-JP based counterpart.

Some of the additions collide with popular Shift JIS extensions, including Windows codepage 932 which is used in web standards (see above). For example, compare plane 1 row 89 in JIS X 0213 (beginning 硃, 硎, 硏…)[17] to row 89 in the JIS X 0208 variant defined in web standards (beginning 纊, 褜, 鍈…).[18] In addition, some of the characters map to Unicode characters beyond the BMP.

Other variants

The space with lead bytes 0xF5 to 0xF9 (beyond the region used for JIS X 0208) is used by Japanese mobile phone operators for pictographs for use in E-mail.[19] KDDI goes further and defines hundreds more in the space with lead bytes 0xF3 and 0xF4.[20]

Beyond even this, there have been numerous minor variations made on Shift JIS, with individual characters here and there altered. Most of these extensions and variants have no IANA registration, so there is much scope for confusion, if the extensions are used.

A variant is the one that must be used if wanting to encode Shift JIS in source code strings of C and similar programming languages. This variant doubles the byte 0x5C if it appears as second byte of a two-byte character, but not if it appears as a single "¥" (ASCII: "\\") character, because 0x5C is the beginning of an escape sequence. The best way of handling this is a special editor which encodes Shift JIS this way.

Shift JIS byte map

As defined in JIS X 0208:1997

The chart below gives the detailed meaning of each byte in a stream encoded in standard Shift JIS (conforming to JIS X 0208:1997).

With vendor or JIS X 0213 extensions

Some of the bytes which are not used for single-byte codes or initial bytes in JIS X 0208:1997 are used by certain extensions, resulting in the layout detailed in the chart below.
