 "Japanese input method by Roman transliteration and Kana-Kanji conversion.

When you use this input method, text entry proceeds in two stages:
Roman-Kana transliteration and Kana-Kanji conversion.  When you start
to enter text, you are in the first stage, Roman-Kana transliteration.
Type SPC to proceed to the next stage, Kana-Kanji conversion.

:: Roman-Kana transliteration ::

You can input any Hiragana character as a sequence of lower-case
letters, Japanese punctuation characters by typing punctuation keys,
Japanese symbols by typing `z' followed by another key.  See below for
a list of all available sequences.  The characters you input are
underlined.

In addition, the following keys provide special effects:

K	Change Hiragana to Katakana or Katakana to Hiragana.
qq	Toggle between this input method and the input method `japanese-ascii'.
qz	Shift to the input method `japanese-zenkaku'.
	Typing \"qh\" will put you back to this input method.
RET	Accept the current character sequence.
SPC	Proceed to the next stage, Kana-Kanji conversion.

The input method `japanese-ascii' is used to enter ASCII characters.
This is almost the same as turning off the input method.  The only
difference is that typing `qq' will put you back into the Japanese
input method.

The input method `japanese-zenkaku' is used to enter full width
JISX0208 characters corresponding to typed ASCII characters.

List of the all key sequences for Roman-Kana transliteration is shown
at the tail.

:: Kana-Kanji conversion ::

You can convert the current Japanese characters (underlined) to
Kana-Kanji mixed text.  In this stage, the converted text is divided
into two parts, the current phrase (highlighted) and the remaining
input (underlined).  The following commands can be used on the
current phrase.

SPC, C-n	kkc-next
	Show the next candidate for the current phrase.
	If successively typed `kkc-show-conversion-list-count' times,
	conversion candidates are shown in the echo area.
C-p		kkc-prev
	Show the previous candidate for the current phrase.
	If successively typed `kkc-show-conversion-list-count' times,
	conversion candidates are shown in the echo area.
l		kkc-show-conversion-list-or-next-group
	Show at most 10 candidates for the current phrase in echo area.
	If typed repeatedly, show the next 10 candidates.
L		kkc-show-conversion-list-or-prev-group
	Show at most 10 candidates for the current phrase in echo area.
	If typed repeatedly, show the previous 10 candidates.
0..9		kkc-select-from-list
	Select a candidate corresponding to the typed number.
H		kkc-hiragana
	Convert the current phrase to Hiragana
K		kkc-katakana
	Convert the current phrase to Katakana
C-o		kkc-longer
	Extend the current phrase; pull in the first character of
	the remaining input.
C-i		kkc-shorter
	Contract the current phrase; drop its last character
	back into the remaining input.
C-f		kkc-next-phrase
	Accept the current phrase.  If there remains input, select
	the first phrase as the current one, and show the first
	candidate for the conversion.
DEL, C-c	kkc-cancel
	Cancel the conversion, shift back to the Roman-Kana
	transliteration.
return		kkc-terminate
	Accept the whole conversion.
C-SPC, C-@	kkc-first-char-only
	Accept the first character of the current conversion,
	delete the remaining input.
C-h		kkc-help
	List these key bindings.
