- In both English and Japanese, the Old Gateau is a pun to the location where it is from.
- Gateau is French for "cake", meaning that in full English, this item is called an "Old Cake".
- Its Japanese name is pronounced the same way as Old Chateau's Japanese name (
森の 洋館). Additionally, Old Gateau's Japanese name translates to "Forest Yōkan". Yōkan is a jelly made from red bean paste.
