• Why do you have 2 instance of Vue, both mounting on #app? You can remove the first one and move your data to the one with the translations. – thefallen Commented Apr 11, 2018 at 13:08

You have to specify i18n in any Vue instance you want vue-i18n to work.

The first instance you have has no i18n specified.

Besides, you have two Vue instances, they don't work together, so what you probably need is just one (with i18n specified).

<div id="app">
  <p>{{ $t("message.hello")}}</p>
</div>
<script src="https://unpkg./vue"></script>
<script src="https://unpkg./vue-i18n/dist/vue-i18n.js"></script>
<script>
  // Ready translated locale messages
  const messages = {
    en: {
      message: {
        hello: 'hello world'
      }
    },
    ja: {
      message: {
        hello: 'こんにちは、世界'
      }
    }
  }
  // Create VueI18n instance with options
  const i18n = new VueI18n({
    locale: 'ja', // set locale
    messages, // set locale messages
  })
  // Create a Vue instance with `i18n` option
  const app = new Vue({
    el: '#app',
    i18n, // this is equivalent to `i18n: i18n,` (without quotes, naturally)
    data: {
      products: [
        'Boots',
      ]
    },
  })
  // Now the app has started!
</script>
