“We’d love our child to go to Japanese Saturday school, but it’s too far.” “It eats the whole weekend.” “Our kid doesn’t want to go.” “The level doesn’t fit and they can’t keep up.” More and more families raising children overseas quietly share these worries — and yes, parents really do search for an online alternative to Japanese supplementary school. This guide lays out why supplementary school becomes hard to sustain, honestly compares the online options that can replace it, and shows how to choose without regret. The short version: what matters most is being able to keep going — and the biggest reason kids keep going is whether they have friends.
What is Japanese supplementary school — and why is it hard?
Japanese supplementary schools (hoshuko) teach Japanese school subjects “in Japanese,” usually on Saturdays, to children who attend local or international schools abroad. According to Japan’s MEXT, there were 242 schools across 51 countries and one region, with about 21,000 students, as of 2024. They’re a precious link to Japan — but most are run by parent-led groups, and these burdens increasingly make them hard to sustain:
- Commute & driving: 30 minutes each way is considered close; some travel 1–2 hours. It assumes a parent’s car, and where there’s no school nearby, attending is simply impossible.
- Saturdays disappear: It clashes with local sports, events and birthday parties, and many families drift away.
- The “5th-grade wall” — level mismatch: It follows Japan’s national curriculum at a fast pace, so children in permanent-resident or international-marriage families often stumble on grade-level kanji and drop out. Others find it too easy and get bored.
- Capacity & lotteries: Kindergarten and lower grades are popular; some schools run lotteries or waitlists.
- Cost: Tuition can run around US$3,000/year plus enrollment, facility and material fees — and the hours spent driving add up too.
The key point: leaving supplementary school does not mean giving up on Japanese. If it’s out of reach or a poor fit, you can simply switch to a place your child can actually keep going to.
Online options that can replace supplementary school
Online alternatives fall into roughly three types, differing in whether kids make friends, whether it’s built for children, and whether it lasts.
| Type | Format | Makes friends | Built for kids | Best for |
|---|---|---|---|---|
| Online supplementary schools | Small group, textbook-based | ○ (kids abroad together) | ○ | Wanting to keep up subject study |
| Tutor marketplaces (italki / Preply) | 1-on-1, pick a tutor | × | △ (general, adults to kids) | Fixing a clear weak point efficiently |
| Correspondence courses (Kumon, Z-kai, etc. overseas) | Self-study worksheets / tablet | × | ○ | Building basics at your own pace |
| TOMODACHI JAPAN | Small group, unlimited | ◎ (peers living in Japan) | ◎ | Having fun, lasting & making friends |
The crucial thing: most options can “teach,” but kids don’t make friends. Correspondence courses and 1-on-1 lessons tend to become “doing it alone,” so the urge to “do it again” fades. Online supplementary schools do build peer connections — but mostly among Japanese-heritage children living abroad.
The real test is “will it last?” — and friends are the key
The most common voices from families who left supplementary school: “alone, it didn’t last” and “it was boring, so they didn’t want to go.” In other words, whether a child keeps going is mostly decided by whether there are peers. Judge your options by these five:
- Low burden on parents (no driving, no material wrangling, works across time zones)
- Does the child think “this is fun — I want to see them again”? (= it lasts)
- Does it fit your child’s level? (mixed-heritage, advanced, or absolute beginner all have a place)
- Will they make friends in the same situation? (no isolation)
- Do the cost and the long-term value of a tie to Japan add up?
How TOMODACHI JAPAN solves the “hard parts” of supplementary school
1. A group — so they make friends and keep going
TOMODACHI JAPAN isn’t 1-on-1 or self-study — it’s a small group. Children talk, play and learn together. “I want to see my friends again” becomes the engine, so your child gets back the peers they lost — with zero driving. The more a child has quit an app or a tutor before, the better a group works.
2. The other side is “peers living in Japan” — the biggest difference
Most online supplementary schools connect Japanese-heritage kids abroad with each other. TOMODACHI JAPAN connects your child with real, same-age children living in Japan from our sister school, NIJIN Academy (1,000+ students). Kids abroad make friends in Japan; kids in Japan make new friends too. Japanese grows not because “it’s study,” but because “I want to talk to my friend.” When they visit Japan, talk to grandparents, or feel their roots — those friendships keep paying off.
3. Built for kids — so there’s no “level wall”
That “5th-grade wall” where kids stumble? TOMODACHI JAPAN doesn’t march everyone through Japan’s curriculum in lockstep. It’s built for children, with classes grouped by conversation level. A beginner who can’t read hiragana yet and a child who was bored because it was too easy can both start at their own level, and have fun. Progress is measured by “How many friends did you make?” — not test scores. And at about US$140/month, unlimited, the more your child joins, the lower the cost per session.
Frequently asked questions
If we leave supplementary school, will our child still learn Japanese?
Yes. What matters is lasting. Switching to a place they can enjoy and sustain grows Japanese more than burning out. Vocabulary and conversation develop naturally while talking with friends.
We live in a country with no supplementary school nearby. Can we join?
Yes. Because it’s online, you can join from anywhere in the world. As long as the time zones work, children in areas without a supplementary school can connect with peers in Japan.
Is it okay for a complete beginner or a shy child?
Absolutely. Classes are grouped by conversation level, so your child starts with peers at the same stage. Even just listening at first is fine — once they make a friend, they naturally want to talk.
Can we use it alongside supplementary school?
Of course. “Reading and writing at supplementary school + conversation and friends at TOMODACHI JAPAN” is an effective combination that fills each other’s gaps. If your child can read and write but can’t speak, a place for conversation and friends fits especially well.
