Raising Bilingual Children in Japan: Keeping Your Home Language Alive
Updated: 2026-09-17
Quick answer
Hi, I'm Miya, and I help newcomers settle into life in Japan. If your family speaks another language at home, you've probably wondered how to keep it going once your child spends most of the day in Japanese at nursery or school. This guide is about daily family life, not choosing a school, so it looks at routines, books, media, community classes and staying close to relatives. Every family's situation is different, and there's no single right way to do it.
The short version: decide roughly who speaks what and when, and keep it relaxed rather than strict. Make the home language fun and useful through stories, songs, games and calls with relatives. Look for books at your local library and connect with other parents who share your language. And if your child starts answering in Japanese, that's very common, so keep offering the home language warmly and patiently.
Setting up a family language routine
Many families find it helps to have a simple, predictable pattern for when the home language is used. Some choose one parent, one language, where each parent consistently speaks their own language with the child. Others speak the home language by everyone at home and leave Japanese to nursery, school and the neighbourhood. Some pick particular times, such as dinner, bath time or weekend mornings, as home-language time.
Whatever you choose, it usually works best when it feels natural for your family rather than like a rule to police. Talk with your partner about what's realistic, especially if one of you speaks Japanese as a first language or is still learning the home language. Routines can change as children grow, and adjusting them is perfectly fine. If you have questions about your child's speech or language development, your municipal health centre (hokenjo or hoken sentā, 保健センター) or your child's doctor is the place to ask.
Reading, songs and media at home
Reading together in the home language is one of the simplest habits to build, even for a few minutes before bed. Picture books, comics, songs and rhymes give children words they might not hear in everyday conversation in Japan. Letting your child choose what to read, or retelling a favourite story together, keeps it enjoyable. Older children may like keeping a simple diary, writing cards to relatives or cooking from a recipe in the home language.
Videos, films and audio stories in your language can add variety, especially when you watch or listen together and chat about them afterwards. It's worth setting screen-time limits that suit your family, just as you would for any media. Many families also keep a small shelf or box of home-language books and games so they're easy to reach. Swapping books with other families is a friendly way to keep the collection fresh without buying more.
Finding books at your local library
Public libraries in Japan (toshokan, 図書館) are free to join for residents, and you can usually register with your residence card or another document showing your address. Many libraries have a children's section with regular story times, and some keep a shelf of foreign-language books. What's available varies a lot between municipalities, so ask at the counter which languages they hold.
If your branch doesn't have much, staff can often order books from other branches in the same city, and some areas have a central or prefectural library with a larger collection. Libraries sometimes host multilingual story events or know of local international associations (kokusai kōryū kyōkai, 国際交流協会) that run activities for families. Your municipal office or local international association can also tell you about support for foreign-resident families in your area.
Weekend classes and parent communities
In many parts of Japan, parents who share a language run weekend or after-school heritage-language classes, playgroups or reading circles. These are often volunteer-led and informal, meeting in community centres, churches, libraries or rented rooms. For children, simply seeing other kids speak the same language at home can make it feel normal and worth using. Local international associations, community centres and embassies or cultural associations of your country may know what exists near you.
Parent groups online and in person are also a good way to share books, swap tips and find playmates. Classes differ a lot in size, style and cost, so it's a good idea to visit or ask questions before joining. If there's nothing nearby, a few families meeting regularly at a park or someone's home can work just as well. Keep it light, because the aim is for your child to enjoy the language.
Staying close to grandparents and family abroad
Relatives back home are often the most motivating reason for a child to use the home language. Regular video calls with grandparents, aunts, uncles and cousins give children a real person to talk to, not just a lesson. Short, frequent calls tend to work better for young children than long ones, and showing a drawing, a toy or something from the day gives them something to talk about. Keep time zones in mind and find a slot that suits both sides.
Between calls, children can send voice messages, photos or short videos through a messaging app, which is easy for small children who aren't writing yet. Grandparents can read a bedtime story over video or send books and letters by post. Trips home, when they're possible, can give a big boost too. Even simple routines, like a weekly call on the same day, help children feel connected to both sides of their family.
When your child starts preferring Japanese
It's very common for children in Japan to start answering in Japanese, especially once they spend long days at nursery or school with Japanese-speaking friends. This doesn't mean the effort has failed, and many families go through phases like this. Children often understand much more of the home language than they speak. Try not to scold or force it, since pressure can make the language feel like a chore.
Instead, you can keep speaking the home language yourself, gently repeat what they said in your language, or ask a playful question that invites an answer in it. Activities they already enjoy, such as games, cooking, sport or a favourite series, can be done in the home language. Celebrate small moments, and let the language be part of warm family time. If you have concerns, talking with your child's doctor, the municipal health centre or other parents can help you find what fits your family.
Keeping family calls and home-language resources at hand
Here's something that's easy to overlook: so much of keeping a home language alive now runs on your phone. Video calls with grandparents, home-language stories and videos, parent group chats and messages about weekend classes all depend on having a Japanese phone number and data that work wherever you are, whether that's the park, the library or the train home. A local number also makes it easier for nursery, school and community groups to reach you. Setting one up is simple: you apply online with your residence card, verify with a quick eKYC, and eSIM-capable phones can often connect the same day in about fifteen minutes.

Keep your routines relaxed, fill your home with stories and voices from family, and be patient when Japanese takes the lead for a while. Your home language is a gift you can keep sharing.
