##The writing style changes a little when the model is related. It looks like the following. .. ..

  activerecord:
    models:
      user: "user"
      attributes:
        user:
        name: "name"

config/application.rb

config.i18n.default_locale = :ja #add to

• Pull the one defined in ja.yml.

homes/index.htmnl.erb

<h2><%= t '.title'%></h2>
<h2><%= t '.name'%></h2>
<h2><%= t '.text'%></h2>

that's all! !!
