Writing a Letter to Your Japanese Grandparents
A letter to Japanese grandparents works best in simple, warm, polite Japanese: start by asking after their health, share news of your life with small everyday details, thank them for something specific, and end by wishing them well and saying you look forward to seeing or speaking to them. Write large and clear, avoid modern loanwords, and enclose photos if you can. It doesn’t need formal letter conventions; what matters to grandparents is hearing from you, in Japanese if possible.
Why a letter means so much
Many Japanese grandparents don’t use video calls or messaging apps comfortably, and some live alone in the countryside. A letter in the post is something they can hold, read again and show to friends. For families split between Japan and another country, it can also bridge a language gap that has grown between generations. See our guide for heritage learners if you’re working to close that gap yourself.
How polite should it be?
Grandchildren usually speak casually to their grandparents, but in writing, a gentle です・ます style reads naturally and shows care, especially if you don’t see each other often. You don’t need 拝啓 or formal seasonal phrases. A simple line about the season is still a nice touch, such as こちらはすっかり寒くなりました (“it has turned really cold here”).
How you address them depends on the family. Common forms are おじいちゃん and おばあちゃん (grandpa, grandma), but some families use other names. Use whatever they’re called at home. Our guide to Japanese family words explains the options.
What to write about
- Ask after their health first: お元気ですか (“how are you?”). Grandparents expect it, and it frames the rest of the letter.
- Your news: school, work, a new home, a hobby, a trip. Small details bring it to life: what you ate, the weather, something funny that happened.
- Family news, if you’re writing for the family: children’s milestones, a new baby, a pet.
- Thanks for a gift, a call, a visit, or simply for something they taught you as a child.
- A shared memory, like a dish they cooked or a place you went together.
- Looking forward: when you might visit or call next.
Close with 体に気をつけてね or the slightly more polite お体を大切にしてください (“please take care of yourself”).
Make it easy to read
- Write large and clearly, in dark ink.
- Avoid katakana loanwords where a simple Japanese word exists, and explain things from your country that they might not know.
- Vertical or horizontal both work. Vertical writing may feel more familiar to an older reader.
- Enclose printed photos with a short note on the back of each.
- Children can add a drawing or a few words in hiragana. Grandparents treasure these.
Regional dialects
Grandparents in some regions speak a strong local dialect, and may write more standard Japanese than they speak. You don’t need to write in dialect, but if you know a few words they use, including one can make them smile. See Kansai-ben and Japanese dialects.
Why not just use a translation app?
Apps translate words, not family relationships. They may produce stiff, formal Japanese that sounds like a stranger wrote it, or use casual phrasing that feels careless to an older reader. They also miss what a grandparent wants to hear between the lines. A native Japanese writer can keep your own voice, make the Japanese warm and natural, and adjust it for how your family actually talks.
