GoogleMapsの住所のAutoCompleteの表記が英語順となる

GoogleMapsのGeoCodingを行っておりますが、AutoCompleteのフィールドに日本語の住所を入力しても英語での住所表記の順番になって見づらいです。
これはどこをどう直せばいいのかわからないので伺いたいです。

ちなみにRailsアプリです。

View

ruby
1    = form_for @restaurant, url: {action: 'create', locale: I18n.locale} do |r|
2      dl.field
3        dt = r.label (t :map)
4        dd = (t :map_description)
5        #map style="margin-top: 50px; width: 800px;"
6        span = r.label (t :lat)
7        span = r.text_field :lat
8        span = r.label (t :lng)
9        span = r.text_field :lng
10      dl.field
11        dt = r.label (t :deleted_at)
12        dd = r.text_field :deleted_at
13      div.submit_btn
14        = r.submit (t :send_btn), :class => "btn btn-primary", data: {disable_with: (t :confirming), confirm: (t :send_permit)}
15    form
16      = text_field_tag :geocomplete, nil, :size => 80, :style => "position: relative; bottom: 420px;"
