* 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~. If you want it to be another
directory, you must re-set the variable. For example, if you install ~cmigemo~
using

#+BEGIN_SRC bash
  sudo apt-get install cmigemo
#+END_SRC

in ubuntu, you should add:

#+BEGIN_SRC emacs-lisp
  (eval-after-load "migemo"
    (setq migemo-dictionary "/usr/share/migemo/utf-8/migemo-dict"))
#+END_SRC

inside ~dotspacemacs/user-config~.

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

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

inside ~dotspacemacs/user-config~. 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
By default, you can use ~migemo~ for ~avy.el~. For ~ivy.el~, you should add:

#+BEGIN_SRC emacs-lisp
  (require 'avy-migemo-e.g.ivy)
#+END_SRC

inside ~dotspacemacs/user-config~. For ~swiper.el~, you should add:

#+BEGIN_SRC emacs-lisp
  (require 'avy-migemo-e.g.swiper)
#+END_SRC

inside ~dotspacemacs/user-config~. For ~counsel.el~, you should add:

#+BEGIN_SRC emacs-lisp
  (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 [[http://web.archive.org/web/20160719053620/http://openlab.ring.gr.jp/skk/doc.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~.
