German for Japanese speakers: what transfers and what does not

Almost every guide to learning German is written for an English speaker, which means it spends its energy on the things English speakers find surprising. If your first language is Japanese, a different set of things is easy and a different set is hard, and knowing which is which saves months.

What is easier than the guides assume

Pronunciation. German vowels are close to Japanese ones and, unlike English, they are written the way they sound. There is no th, no ambiguous a, and the spelling is close enough to phonetic that a word read aloud from the page is usually right. The genuine difficulties are short: the r, the ch in ich against the one in ach, and the three umlauts. That is a small list compared with what an English speaker has to unlearn.

The verb at the end. In a German subordinate clause the finite verb moves to the end: Ich weiß, dass er morgen kommt. English speakers find this disorienting because it never happens in English. For a Japanese speaker it is the ordinary order, and a clause that ends in a verb reads as normal rather than as a puzzle.

Compounds. German builds long nouns by sticking words together, exactly as Japanese does with kanji compounds. Geschwindigkeitsbegrenzung looks intimidating until you notice it is three words in a trench coat, which is a reflex Japanese readers already have.

Politeness has a grammatical form. German distinguishes du from Sie, and the choice carries social weight. This is a familiar idea, and Japanese speakers tend to handle it more carefully than learners whose language has no such distinction.

The one bridge nobody tells you about

German cases are usually explained as an abstract grammatical concept, and English speakers struggle because English marks almost nothing. Japanese marks it constantly, with particles.

• The subject particle ga does the job of the German Nominativ.
• The object particle o does the job of the Akkusativ.
• The particle ni, marking the recipient, covers much of the Dativ.

The analogy is not perfect and it breaks in places, most obviously because German marks the case on the article rather than after the noun, and because ni covers ground that German splits between the Dativ and several prepositions. But as a first mental model it is far better than the one an English speaker starts with, which is no model at all. Ich gebe dem Mann das Buch has the same three roles, marked in the same three ways, as the Japanese sentence you would write for it.

That means the hard part of German cases, for you, is not the concept. It is the table: four cases times three genders times singular and plural, marked on the article. That is memorisation, and memorisation has a known solution.

What is genuinely hard

Gender. Japanese has nothing like it. Every German noun is der, die or das, it is mostly not predictable from meaning, and the case table above only works once you know which of the three a noun is. There are useful patterns by ending, which we set out in the gender guide, but a large share simply has to be stored with the word.

Plurals. Five patterns, sometimes with an umlaut, not reliably predictable. Same answer: store it with the word rather than deriving it.

Articles at all. Japanese does without them. German requires one in almost every noun phrase and changes its form by case, so the article is doing two jobs at once and neither of them exists in your first language.

The words you already know, and the trap in them

Japanese borrowed heavily from German, mostly through medicine, mountaineering, music and philosophy. You already own a few hundred German words without having studied any: Arbeit, Karte, Thema, Energie, Allergie, Gaze, Hysterie, Rucksack, Gelände, Meister, Märchen, Baumkuchen, Bombe.

The trap is that borrowed words drift. In Japanese, arubaito means a part-time job; German Arbeit means work of any kind, including a full-time career. Karute, a patient's chart in a Japanese hospital, is just Karte, a card, in German. Gerende is a ski slope in Japanese and merely terrain in German.

So treat them as a head start on pronunciation and shape, not on meaning. A borrowed word is a word you can read on sight and must still check.

What to actually do

Learn by frequency, because the first thousand words carry most of an ordinary page. Learn every noun as article + noun + plural, one item rather than three, because that is the form the case table needs. Put the case tables themselves on a review schedule rather than reading them once, because they decay faster than anything else in the language. And read the word in a sentence, not as a gloss.

Where this site fits

We built it, so read accordingly. The vocabulary is in frequency order and every noun carries its article and plural; there are over 14,000 entries with example sentences and translations. The grammar library has 480 points from A1 to C2, each with an explanation and worked examples, and they go through the same review schedule as the words, which is the part most tools leave out. Everything is readable without an account; the placement test exists so that someone who already has German does not have to walk through A1 again.
