Sooner or later, a child learning Japanese asks for a Japanese pen pal: a real friend their own age in Japan to write to. It is a lovely idea, and it is exactly the right instinct. The questions parents type next are always practical: where do you actually find a Japanese pen pal for kids, which sites are safe, what are the age rules, and will it really help with Japanese?
We run an online Japanese school for children growing up outside Japan, and “I want a friend in Japan” is the most common reason our families give for learning in the first place. In October 2026 we read the current terms of the pen pal and language exchange services that parents are usually pointed to, and checked whether the sites in the popular lists still exist. Some of them do not. Here is the honest picture.
The short answer on a Japanese pen pal for kids

- The safest route for a child under 13 is through a school or a teacher, not an open website. Most children who have a pen pal in Japan got one because their class was paired with a class in Japan.
- Open pen pal and language exchange sites have age floors: InterPals 13, Tandem 16, HelloTalk 12 (with a parent’s approval under 18), Postcrossing 13 (younger only with a parent’s authorisation).
- Several sites still recommended in “best pen pal sites for kids” lists no longer exist. When we checked in October 2026, the domains of both Global Pen Pals and World Pen Pals were parked for sale.
- Your child will probably write in English more than Japanese. Children in Japan who sign up for pen pals are usually doing it to practise English. That is fine, but plan for it.
Want your child to have real friends in Japan?
TOMODACHI JAPAN is an online Japanese school for children growing up outside Japan. They talk with peers their own age in Japan every day, taught by teachers working at Japanese schools, in small classes of 8.

Why a Japanese pen pal is harder to find than it sounds
Search for a Japanese pen pal and you will find plenty of adults. Finding a child is different, for three reasons.
- Open sites are built for teenagers and adults. Their age floors start at 12 to 16, and the people your child would meet there are mostly older than they are.
- Children in Japan reach the outside world through their schools. School-to-school letter exchanges are common, and they are run by teachers. A child in Japan is far less likely to be on an international pen pal website on their own.
- The language runs the other way. A Japanese child of ten is learning English at school, so a pen pal exchange is often their English homework. Your child gets a friend and a window into daily life in Japan, but not necessarily much Japanese practice.
None of this is a reason not to do it. It is a reason to choose the route by your child’s age, and to be clear about what a pen pal will and will not give them.
Where to find a Japanese pen pal: the options, checked
1. Your child’s school, or a sister school in Japan
This is the route most children actually take. Schools that teach Japanese often have a partner school in Japan, and the two classes write letters to each other. Local news is full of examples: a high school in Washington State exchanging handwritten letters with a school in Fukuoka, primary schools in Australia writing to classes in Gifu, Wakayama and Kyoto, sometimes followed by a video call where the children finally meet.
What makes it work for a young child: a teacher sets it up, the letters are read before they go, and the pen pal is a real classmate of a real class. If your child’s school teaches Japanese and has no exchange, it is worth asking. If they attend a Japanese Saturday school (hoshuko), ask there too. Postal letters are slow; one Australian class reported that its parcel took about three weeks to reach Japan, so expect a handful of letters a year rather than a weekly conversation.
2. PenPal Schools (classrooms only)
PenPal Schools is a free platform that matches students in different countries, organised by teachers. The teacher creates a class and shares a code, students are matched with a pen pal, and each week they answer discussion questions and exchange written or recorded replies. Teachers can see every message, and the site says messages are also screened by AI for safety. Its focus is practising English, and a parent cannot sign a child up alone: it has to come through a class.
3. Students of the World
A long-running free site (since 1995) with a separate pen pal area for children and students up to 24. Its rules are strict and sensible for a child: no family name, no full birthday (birth year only), no address and no phone number on the profile, and adults over 15 are not allowed to contact children. It says it is moderated every day. It is a reasonable starting point for an older child with a parent beside them, but it does not tell you how many members are in Japan, so do not count on a Japanese match.
4. Postcrossing (postcards, not pen pals)
Postcrossing sends your postcard to a random member somewhere in the world, and someone else sends one back to you. Its terms open the site to people 13 and over, and to younger children only when a parent or guardian authorises it, with the adult responsible for how the child uses it. It is not a pen pal in the sense of one ongoing friend, and you cannot choose Japan, but a postcard from Japan arriving in the letterbox is a real thrill for a young child.
5. Language exchange apps: InterPals, Tandem, HelloTalk
These are where most Japanese pen pals are found online, and they are where parents need to read the small print.
- InterPals: its terms prohibit users under 13. There is no separate section for minors; members can filter who contacts them by age, sex and location.
- Tandem: its terms require users to be 16 or older.
- HelloTalk: children under 12 are not allowed, anyone under 18 needs a parent’s approval, and minors can only search for other minors. We have gone through all of HelloTalk’s age rules in detail here: Is HelloTalk safe for kids?
For a teenager with a parent’s agreement, these can be a good way to practise. For a child of eight or ten, they are not designed for them.
A warning about old “best pen pal sites” lists
Many articles still recommend Global Pen Pals and World Pen Pals for children. In October 2026 the Global Pen Pals domain showed a “domain for sale” page and the World Pen Pals domain redirected to a domain marketplace. Before you hand your child’s details to any pen pal site, open it yourself and check that it is still run by the organisation the article describes.

A safety checklist before your child writes to anyone
- Match the route to the age. Under 13: school or teacher-run exchanges, or postcards with you. Teenagers: a moderated site or exchange app, with your agreement.
- Read the site’s own terms, not a summary. Look for the minimum age and what it says about minors.
- Keep personal details out. No full name, school name, address, phone number or photos that show where you live. For postal letters, use a school or a PO box where you can.
- Read the first letters together. Agree in advance that you will see messages, and why.
- Keep conversations on the platform. A request to move to another app, or to send photos, is a reason to stop.
- Check the site still exists and is run by who it claims to be.
What a Japanese pen pal will, and will not, do for your child’s Japanese

A pen pal is wonderful for motivation. A letter from a real child in Japan, with a drawing, a sticker and a photo of their school lunch, makes Japanese feel like a language people actually live in. Many children who stop practising at home start again when they have someone to write to.
What it does not give is regular speaking practice. Letters are slow, often half in English, and depend on the other child keeping up. If what your child really wants is to talk with Japanese children their own age, week after week, a pen pal on its own will not get them there. The two work best together: a pen pal for the friendship and the letters, and something live for the conversation.
If your family lives in Japan and the problem is the opposite one, a child surrounded by Japanese but without Japanese friends, we wrote about that separately: Living in Japan but your child has no Japanese friends?
Where TOMODACHI JAPAN fits
TOMODACHI JAPAN (tomodachi means “friend”) is an online Japanese school built around the thing a pen pal promises: real friends in Japan. Children growing up outside Japan learn in live classes of up to 8, taught by teachers from Japanese schools, and they talk with children their own age in Japan as part of the programme. The conversation is supervised by teachers, in a class, rather than one-to-one with a stranger.
It does not replace a good pen pal. If your child’s class already has a sister school in Japan, keep writing those letters. What we add is the speaking: a place where your child uses Japanese with Japanese peers every week, so that the next letter they write is in more Japanese than the last one.
Frequently asked questions
How can my child get a Japanese pen pal?
For a younger child, ask their school, their Japanese teacher or their Saturday school whether they have a partner class in Japan. That is how most children find one. Teenagers can use moderated sites or language exchange apps with a parent’s agreement, after checking the minimum age.
Is there a free Japanese pen pal site for kids?
PenPal Schools is free but only works through a teacher’s class. Students of the World is free and has a children’s area with strict profile rules, though it does not say how many members are in Japan. School exchanges usually cost nothing beyond postage.
What age can you use InterPals or Tandem?
InterPals’ terms prohibit users under 13. Tandem’s terms require users to be 16 or older. HelloTalk does not allow children under 12 and requires a parent’s approval for anyone under 18.
Will a pen pal help my child speak Japanese?
It helps with motivation, reading and writing, and a little vocabulary. It rarely helps with speaking, because letters are slow and Japanese children often write in English to practise. For speaking, pair it with live conversation.
In short
The best Japanese pen pal for a child usually comes through a school, not a website. Open sites start at 12 to 16 and are mostly used by older people, and some sites still on popular lists have closed. Choose the route by age, read the first letters together, and pair the letters with a place where your child actually speaks Japanese with children in Japan.
