I'm quite surprised that you can play Jap game without knowing Japanese
Did you choose the correct order to save ?
For example :
セーブしますか(Do you want to save ?)
はい(Yes) いええ(No)
Well , i don't have that game , you should post a screenshot that show the dialog
イナズマイレブンgo ストライカーズ 2013のデータセーブに失敗しました。 -> Fail to save Inazuma....2013 data
