諸説ありますがこれでいけました。
下記記載の各 RUN コマンドを実行しないとうまくいきませんでした。

Docker Imageはruby2.4.3(おそらくUbuntu16)。

# Japanese
RUN apt-get update \
    && apt-get install -y locales \
    && locale-gen ja_JP.UTF-8
ENV LANG ja_JP.UTF-8
ENV LANGUAGE ja_JP:ja
ENV LC_ALL=ja_JP.UTF-8
RUN localedef -f UTF-8 -i ja_JP ja_JP.utf8

おまけ

日本語環境の設定という点では、時刻をUTCからJST表示にするのも良いでしょう。

docker-composeを使用している場合はdocker-compose.ymlで

docker-compose.yml

web:
  environment:
    TZ: Japan

とすると、JST表示になります。
