True... Actually I wonder how I have to read the zic files in this case.
It says:

Rule    Japan    1948    only    -    May    Sun>=1    2:00    1:00    D
Rule    Japan    1948    1951    -    Sep    Sat>=8    2:00    0    S
Rule    Japan    1949    only    -    Apr    Sun>=1    2:00    1:00    D
Rule    Japan    1950    1951    -    May    Sun>=1    2:00    1:00    D

Zone    Asia/Tokyo    9:18:59    -    LMT    1887 Dec 31 15:00u        9:00    -    JST    1896        9:00    -    CJT
  1938        9:00    Japan    J%sT
 

The last column of the rules tell us what to put in for %s, but why is there
no

Rule    Japan    19xx    max    ....                                    S

rule? I.e. a rule saying that after some date we should always replace %s
by S? What am I missing here?
