Are ready-made Japanese flashcards enough?

They are enough when the library matches the Japanese you will actually meet this month and you will keep the daily load small. They stop being enough when most new words come from your reading, class, or job.

Should beginners make their own Anki deck?

Usually no. Building cards is a second skill. Learn kana, start a tiny prepared set or a tiny trusted deck, and add custom cards when you have sentences worth keeping.

Ready-made Japanese flashcards versus a deck you build

Prepared cards remove the curriculum job. Custom cards preserve your actual Japanese. Start with the smaller job, and switch only when the library no longer matches what you meet.

People argue about flashcard apps when they are really arguing about who chooses the words.

A ready-made library answers “what should I review?” for you. A deck you build answers “how do I keep this exact sentence?” Both can use spaced repetition. They are not interchangeable.

Prepared cards earn their keep early

Beginners often do not have a personal corpus. They have a script to learn, a first few hundred words, and a wish to hear those words. A checked library with audio removes a week of deck shopping.

That is the job Inku is built for on iPhone: kana, JLPT-labeled vocabulary, topic decks, and phrases, with bundled audio. The official site, checked 1 Sep 2026, publishes those catalog counts. It is still a library with edges. It does not become your textbook, your tutor, or your novel.

Inku’s public Japanese flashcards page is the product tour for that library. The independent decision pages here are Inku vs Anki and Japanese flashcards on iPhone.

Custom cards earn their keep later

Once you read, listen, or take a class, the useful items are no longer a publisher’s N5 list. They are the word you missed on a page, the grammar you keep recognizing too late, the name of the dish you actually order.

Anki exists for that moment. You can put the exact expression, reading, meaning, and audio you need on a note. You also inherit the maintenance: grading, suspending junk, and not importing 5,000 cards because a forum said so.

If most of your time is spent styling cards, you are not studying Japanese. You are studying Anki.

A simple switch rule

Stay on prepared cards while these stay true:

you can name the deck’s job in one sentence;
the items show up in the Japanese you already do;
reviews fit a weekday.

Move the new items to a personal deck when:

you keep skipping prepared cards because they are not your life;
you have a repeating source (textbook chapter, graded reader, tutor notes);
you care more about those sentences than about finishing someone else’s list.

You can keep a prepared iPhone loop for phrases and give Anki the mined sentences. You should not copy the same lemma into both queues. Inku vs Anki is the product-level version of this rule.

What this is not

This is not an argument that custom decks are more serious. Fluency does not award points for suffering through empty note types.

It is also not an argument that a prepared library is “beginner-only” as a moral rank. It is beginner-shaped because the first bottleneck is usually selection, not templates.

Pick the smaller job. Add the heavier tool when the Japanese in front of you demands it.
