* Install
** Layer
To use this configuration layer, add it to your =~/.spacemacs=. You will need to
add =japanese= to the existing =dotspacemacs-configuration-layers= list in this
file.

** Configuration
For a basic configuration, add this to your =~/.spacemacs= inside ~dotspacemacs/user-config~:

*** evil-tutor-ja
By default, the variable ~evil-tutor-working-ja-directory~ is assigned =~/.emacs.d/.tutor-ja=.

*** migemo
By default, the variable ~migemo-dictionary~ is assigned
~/usr/local/share/migemo/utf-8/migemo-dict~ in MacOS, or ~/usr/local/cmigemo/utf-8/migemo-dict~ in linux.
If you want it to be another directory, you must re-set the variable.
For example, if you install [[https://www.kaoriya.net/software/cmigemo/][C/Migemo for Windows 64bit]] in the directory ~c:\app\cmigemo-default-win64~, you should add:

#+BEGIN_SRC emacs-lisp
  (with-eval-after-load "migemo"
    (setq migemo-dictionary "c:/app/cmigemo-default-win64/dict/utf-8/migemo-dict"))
#+END_SRC

inside ~dotspacemacs/user-config~, or

#+begin_src emacs-lisp
  (japanese :variables
            migemo-dictionary "c:/app/cmigemo-default-win64/dict/utf-8/migemo-dict")
#+end_src

inside ~dotspacemacs-configuration-layers~.

*** helm-with-migemo
If you want to use helm with migemo, you should add:

#+BEGIN_SRC emacs-lisp
  (with-eval-after-load "migemo"
    (helm-migemo-mode 1))
#+END_SRC

inside ~dotspacemacs/user-config~, or

#+begin_src emacs-lisp
  (japanese :variables
             helm-migemo-mode 1)
#+end_src

inside ~dotspacemacs-configuration-layers~. Note that you may find in a package called
~helm-migemo.el~ in MELPA. However, this package is deprecated and not supported
by helm.

*** avy-migemo
Note that ~avy-migemo~ in MELPA does not work
currently, so you had better use a [[https://github.com/tam17aki/avy-migemo][forked version]] alternatively.

By default, you can use ~avy-migemo~ for ~helm-mode~. For ~ivy-mode~, you should add:

#+BEGIN_SRC emacs-lisp
  (with-eval-after-load "migemo"
    (require 'avy-migemo-e.g.ivy)
    (require 'avy-migemo-e.g.swiper)
    (require 'avy-migemo-e.g.counsel))
#+END_SRC

inside ~dotspacemacs/user-config~.

*** ddskk
You can write a configuration file ~​~/.skk~. For detailed configuration, see
some [[https://skk-dev.github.io/ddskk/skk.html][documents]].

*** pangu-spacing
By default, ~pangu-spacing-mode~ is applied to ~text-mode~. If you prefer the
mode globally, add:

#+BEGIN_SRC emacs-lisp
  (global-pangu-spacing-mode 1)
#+END_SRC

inside ~dotspacemacs/user-config~.

* Key bindings
By default, ~C-x j~ toggles ~skk-mode~.
