Kaishi 1.5k Deck Guide: Best Anki Setup for Japanese
Use a curated deck without creating a review backlog
TL;DR
Kaishi 1.5k is a strong early Japanese vocabulary deck when you already know kana and can review daily. It should be treated as a foundation, not a complete Japanese course. Flica fits beside it by turning your own reading, lessons, and videos into smaller personal cards.
Japanese learners often collect too many decks before the first one becomes useful. Kaishi 1.5k is attractive because it feels manageable, but even a small deck can become a backlog if you add too much too quickly.
This guide explains who should use Kaishi, how it compares with Core and JLPT decks, and how to combine a curated deck with personal AI-made cards without losing control.
What Kaishi 1.5k is best for
Kaishi 1.5k is popular because it focuses on a practical early Japanese base rather than overwhelming beginners with a huge deck. The search demand around kaishi deck terms in the Flica GSC snapshot suggests learners want a dedicated explanation, not just a mention inside a broad Japanese deck roundup.
Who should use it
Use Kaishi when you are past kana, want a structured vocabulary base, and can review daily. It is less useful if you are still learning hiragana and katakana, or if your main goal is kanji handwriting practice. The deck is a vocabulary foundation, not a full course.
Kaishi vs other Japanese decks
The right deck depends on your current study source.
| Deck | Best use | Main caution |
|---|---|---|
| Kaishi 1.5k | Early vocabulary base | Still needs reading practice |
| Core 2k/6k | Broad frequency vocabulary | Can feel large |
| Tango N5 | JLPT style sentences | Book alignment matters |
| Kanji decks | Character recognition | Not enough for usage alone |
How to review without drowning
Start with a low new-card count and let reviews stabilize. If you add too many cards on day one, the deck feels fine for a week and then turns into a backlog. A safer start is a small daily batch, sentence reading beside the deck, and immediate suspension of cards that are confusing rather than useful.
Where AI flashcards fit
Flica should not replace a curated deck like Kaishi when you need a fixed beginner sequence. It fits beside it: turn textbook sentences, YouTube transcripts, or class notes into extra cards that match what you actually encountered. That keeps the main deck stable while your personal deck captures context.
Setup checklist
Before you import anything, make the workflow sustainable.
- Finish kana first.
- Pick one main vocabulary deck.
- Keep new cards low for two weeks.
- Add personal sentence cards separately.
- Review before adding more material.
FAQ
Is Kaishi 1.5k good for beginners?
It is good for learners who already know kana and want a manageable vocabulary base. Absolute beginners should learn kana first.
Is Kaishi better than Core 2k?
Not universally. Kaishi is smaller and often easier to start. Core decks are broader but can feel heavier.
Can I use Flica with Kaishi?
Yes. Keep Kaishi as the structured base and use Flica for personal cards from lessons, videos, and reading notes.
How many new cards should I do?
Start low enough that reviews stay easy to finish. Consistency is more important than speed.
Let Kaishi be the base, not the whole system
Kaishi 1.5k works best as a controlled foundation. It gives you a starting vocabulary base, but real progress still needs reading, listening, and sentences you personally meet.
Use Flica for those personal materials so your extra cards stay connected to actual study instead of becoming another random deck.
