Answer 1

For default foreign language (example Japanese)

STEP 1 Create a 'ja.yml' in config/locales/ (or whatever filename)

ja:
  devise:    
    mailer:
      confirmation_instructions:
        subject: '仮会員登録完了のお知らせ'
      reset_password_instructions:
        subject: 'パスワード再設定手順のお知らせ'

STEP 2 On config/environments/development.rb

config.i18n.default_locale = :ja

STEP 3 Restart server
