By age 6 or so, most Japanese children have mastered thousands of spoken words and can hold complex conversations about everything from their favourite foods to playground politics. They understand nuance, humour, and can navigate the intricate social hierarchy of Japanese politeness levels. Yet many of these same children can barely read a simple sentence or write their own name in kanji.

This isn't a learning disability, it's exactly how language acquisition is supposed to work. Japanese children naturally learn most of the vocabulary before they turn 6, and even if they don't know many kanji yet, they have no trouble communicating because they learned how to speak before they could read.

But as an adult learning Japanese as a second or third language, you don't have that luxury. And most apps pretend you do.

The Natural Order: Speech First, Everything Else Later

Here's how Japanese children actually acquire their language:

Ages 0-2: Sound recognition and basic words. Japanese children begin learning and using polite speech in basic forms from an early age, building an intuitive understanding of the language's social dynamics.

Ages 2-6: Vocabulary explosion. By age 6, children have acquired thousands of spoken Japanese words through constant immersion. They understand complex grammar patterns not through explicit instruction, but through patterns absorbed from millions of conversational examples.

Ages 6-12: Reading and writing introduction. Only after establishing this massive spoken vocabulary foundation do children begin learning kanji systematically in school. Even then, they often encounter words they can already say and understand, they're just learning how to represent familiar concepts in writing.

The crucial point: Japanese children have a 6-year head start on vocabulary acquisition before they worry about reading or writing. Their spoken foundation makes everything else possible.

Your Adult Learning Reality

As an non-native learning Japanese, you face a completely different challenge. You don't have the luxury of 6 years of immersive vocabulary building before tackling reading. You need to compress this process dramatically.

But here's what most language learning apps get wrong: they try to teach you like a Japanese child, but without giving you the vocabulary foundation that makes the child's approach work.

The Duolingo Problem

Apps like Duolingo throw you random sentences, "The turtle eats bread", while expecting you to absorb grammar patterns through repetition. This osmosis approach can work, but only if you already have the vocabulary base to make sense of the patterns. Children have this base, you don't.

The Textbook Problem

Traditional textbooks teach grammar rules explicitly, but often with artificial example sentences using limited vocabulary and usually feel outdated. You learn grammar structures but lack the word knowledge to use them with real Japanese content.

The Reading-First Problem

Many apps emphasise reading and writing from day one, putting you in the position of trying to decode written Japanese when you don't yet have the spoken vocabulary that would make those written words meaningful.

The Vocabulary-First Solution

Since you can't replicate a child's 6-year immersion experience, you need a different approach. Instead of speech-first learning, adult Japanese acquisition works better with vocabulary-first learning:

Step 1: Build Your Vocabulary Foundation

Before you worry about complex grammar or reading fluency, you need words. Lots of them. Not random words, but the high-frequency vocabulary that appears in 70% of Japanese communication.

The first 1000 most common Japanese words aren't just statistics, they're the building blocks that make everything else possible. When you know these words, Japanese sentences start making sense even when you don't understand every grammar pattern.

Step 2: Recognition Before Production

You need to recognise and understand Japanese words before you can use them confidently in speech. This is the opposite of how children learn (who speak words before they fully understand them), but it's more efficient for adults with limited study time.

Step 3: Context-Driven Learning

Instead of artificial textbook sentences, learn vocabulary within contexts you'll actually encounter. If you want to understand anime, learn anime vocabulary. If you need business Japanese, start with workplace terms. This gives your vocabulary immediate practical value.

Why Kann Understands This Difference

This is exactly why Kann takes a vocabulary-first approach rather than trying to replicate children's language acquisition:

Frequency-Based Foundation

We start with the 1000 most common Japanese words, the vocabulary base that Japanese children acquire naturally through immersion, but that you need to learn systematically and efficiently.

Topic-Specific Expansion

Once you have that foundation, you can expand into specific areas (Business, Anime, Technology, etc.) based on your actual needs and interests. This gives you context and motivation that pure textbook vocabulary lacks.

Recognition Mastery

Instead of stroke order practice or production exercises, Kann focuses on recognition and comprehension, the skills that directly transfer to understanding real Japanese content.

Multiple Question Types

We test your vocabulary knowledge from different angles ("What's the reading of …?", "What does … mean?", "What's the word for...?") to build robust recognition that works across different contexts.

The Practical Difference

Japanese Child's Path: Speech → Understanding → Reading → Writing → Advanced literacy

Your Path Should Be: Vocabulary recognition → Reading comprehension → Speech production → Writing

Ideal Path: Vocabulary recognition → Move to Japan → Struggle a bit → Reading → Speech production → Writing

What Most Apps Try to Do: Grammar rules → Random sentences → Everything at once → Confusion

The Bottom Line

Japanese children have a natural advantage: 6 years of vocabulary acquisition before formal language education begins. You don't have that luxury, but you do have advantages children lack: analytical thinking, pattern recognition, and the ability to learn systematically.

The key is using an approach designed for non-native learners rather than trying to replicate childhood acquisition. Focus on building vocabulary first, prioritise recognition over production, and choose words that match your actual goals and interests.

You won't learn like a Japanese child, and that's actually better. You can learn more efficiently, more purposefully, and with clearer progress markers. But only if you use methods designed for how we actually acquire second languages.

Speech is still the goal. But vocabulary is the foundation that makes everything else possible.
