+# Today's _Asahi Evening News_ (page 4) reports that Japan had
+# daylight saving between 1948 and 1951, but ``the system was discontinued
+# because the public believed it would lead to longer working hours.''
+# Shanks writes that daylight saving in Japan during those years was as follows:
+# Rule NAME FROM TO TYPE IN ON AT SAVE LETTER/S
+#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
+# but the only locations using it were US military bases.
+# We go with Shanks and omit daylight saving in those years for Asia/Tokyo.
+#
+# The same news article also reports that Japan is likely to go on DST in 1996
+# as follows, where I've guessed the AT and LETTER/S columns:
+# Rule NAME FROM TO TYPE IN ON AT SAVE LETTER/S
+#Rule Japan 1996 max - Apr Sun>=1 2:00 1:00 D
