In our previous post, we discussed the various words for ‘grandmother’ in Japanese. Accordingly, it is only right that we teach you how to say ‘grandfather’ in Japanese! 

We will also learn the term for the collective of the two, ‘grandparents’.

Ojiisan 

お爺さん

Grandfather

The standard word for ‘grandfather’ in Japanese is ojiisan (お爺さん / おじいさん). Variations of this term include ojiichan, jiichan and jiisan

These names are used when speaking directly to your own grandfather, and also when referring to someone else’s grandfather. 

Sofu

祖父

Grandfather (formal)

Sofu (祖父 / そふ) is a slightly more formal, polite term for ‘grandfather’ in Japanese. 

This term is used when talking to others about one’s own grandfather. If you use ojiisan or its variations in conversation with someone you are not close with, you may come across as brash and over casual.

Jiiji 

じいじ

Grandpa 

Jiiji (じいじ) is what children usually call their grandfathers as a child learning to talk, as naturally, jiiji rolls off the tongue easier than ojiisan!

Jiiji is an endearing nickname that can be used by children and adults alike, as it expresses a loving and close relationship with one’s grandfather.

How to refer to both grandparents 

To refer to both grandparents, you of course can use both words and simply say ‘grandfather and grandmother’ (おじいさんおばあさん)

However, if you combine the individual terms of sofu and sobo (‘grandmother’), you get sofubo (祖父母 / そふぼ) which means ‘grandparents’! 

Things to note

Similarly to the words we went over for ‘grandmother’, there are a couple of things to keep in mind with terminology related to ‘grandfather’ also.

  • Ojiisan, the standard word for ‘grandfather’, can also be used to refer to any elderly man. That’s why, in order to prevent confusion, sofu is used when you want to let it be known that you are in fact speaking about your own grandfather and not just a random old man!
  • The Japanese word for ‘uncle’ is ojisan (叔父さん / おじさん). It has a shorter ‘i’ sound, compared to the elongated i’ in ojiisan
  • The term for ‘great-grandfather’ is hii (pronounced hee) jiisan (曾祖父さん / ひいじいさん).  Additionally, when speaking about your great-grandfather to others, opt for the term sousofu (曽祖父 / そうそふ).
