I did so, and confirmed that tcsh/csh can printenv '~' char in
environment variable with the new LC_CTYPE:
 +----------------------------------------
 |-r--r--r--  1 root wheel 4700 Dec  1 04:14
/usr/share/locale/ja_JP.SJIS/LC_CTYPE
 |MD5 (/usr/share/locale/ja_JP.SJIS/LC_CTYPE) =
13bb935e7ba1275a263cf0074ceaa352
 +----------------------------------------

 - * - * -

I analyzed your new map file by text processing
because I am not familiar with either KANJI-codes
or LC_CTYPE with multibyte chars.

Here are files used:
 +----------------------------------------
 |MD5 (map.SJIS.orig) = 5a3ff0eb3cf5efe1fa9d44dc6a494e57 ...of 14.0R...[A]
 |MD5 (map.SJIS.yuri) = 7adad9b105608e4fd16a5e9f00af7a43 ... yours  ...[B]
 +----------------------------------------

[A] has 11495 mappings, including 96 aliases for chars under 0x7f
                              and | <YEN_SIGN> \x5c
                                  | <OVERLINE> \x7e
[B] has  7166 mappings, including same 96 aliases for chars under 0x7f
                              and | <REVERSE_SOLIDUS>       \x5C
                                  | <TILDE>                 \x7E
So [B] has less 4329 mappings than [A].

The attached file: "www-disappeared.txt" (handle as [C]) is
the list of disappeared mappings from [A] to [B], sorted by code.
It has 4331 entries including <YEN_SIGN> and <OVERLINE>.

I am using this web page as (easy) reference about SJIS code.
  http://charset.7jp.net/sjis.html
Chars with light-blue-background in the bottom table are
not recommended to use by the author because
they can not be mapped to unicode,
including 'machine/OS dependent characters'.

I confirmed, by my eyes, disappeared mappings in [C] with the table,
they all are on light-blue-background.

So your [B] should be fine, I think.
