Chapter 2 — Essential Tools Setup

You need a small set of tools. Install them, configure them, and then stop tinkering. The biggest trap at this stage is spending hours optimizing your setup instead of actually using Japanese. Get through this chapter in one sitting, then go immerse.

Yomitan — Browser Popup Dictionary

What it is: A browser extension that lets you hover over Japanese text on any webpage and instantly see definitions, readings, and pitch accent information. It is the successor to the now-discontinued Yomichan.

Setup:

  1. Install Yomitan from yomitan.wiki.
  2. Download and import the Jitendex dictionary — it is a well-maintained, free Japanese-English dictionary optimized for Yomitan.
  3. Optionally add a pitch accent dictionary (you will care more about this later, but it costs nothing to install now).

Once installed, you can read Japanese text on any website and look up words by holding Shift and hovering. This single tool will transform your reading ability overnight.

Vocabulary Practice — Productive Recall and Cloze

What it is: Your daily vocabulary practice should prioritize producing Japanese, not just recognizing it. The research is clear: productive recall (seeing a meaning and producing the word) and cloze deletions (filling in a blanked word within a sentence) outperform standard recognition flashcards. See The 2026 Learning Stack chapter for the full evidence.

The primary approach:

  1. For new words, create productive recall cards — the English meaning or a picture on the front, and you produce the Japanese word (type it or say it aloud).
  2. For mined sentences, use cloze deletion format — a real Japanese sentence with the target word blanked out. Fill in the blank from memory.
  3. Run a weekly cumulative quiz — mix all vocabulary from the past 1-2 weeks in a single test. This is 2-3x more effective than daily item-by-item review.

You can use any tool for this: a simple spreadsheet, a notes app with self-testing, or a dedicated flashcard app.

If you prefer Anki: Anki works fine as the vehicle for this approach. Install it from apps.ankiweb.net. Switch to the FSRS scheduler (built into recent versions — it reduces review count by 20-30%). Download the Kaishi 1.5k deck as a starting vocabulary base. Then add productive recall and cloze cards as you mine sentences from immersion.

The overuse warning still applies: Whatever tool you use, cap vocabulary practice at 15-20 minutes per day. If reviews are ballooning past that, reduce new cards. Vocabulary practice is supplementary — immersion is the main event.

Kanji Handwriting — Notebook and Pen

What it is: Brief daily handwriting practice for new kanji. Neuroscience research (2024 EEG studies) shows handwriting activates deep encoding networks that typing does not.

Setup: A notebook and a pen. That is it.

How to use it: When you encounter a new kanji, write it 3-5 times with correct stroke order. Combine with radical decomposition — learn the component radicals and their spatial relationships. Five minutes per day is enough. This is not calligraphy practice; it is a memory encoding tool.

jpdb.io — Difficulty Ratings

What it is: A database that rates the difficulty of Japanese media — anime, visual novels, novels, and more — on a 0-100 scale based on vocabulary frequency.

How to use it: Before starting a new anime or visual novel, look it up on jpdb.io. A show rated 30 will be significantly more approachable than one rated 70. At your level, aim for content rated below 50, but do not treat the number as a hard rule. If a show rated 60 is the only thing that interests you, watch it anyway. Interest beats difficulty every time.

Natively — Book and Manga Difficulty

What it is: A community-driven site that assigns Elo-based difficulty ratings to Japanese books and manga. Think of it as a matchmaking system between you and reading material.

How to use it: Create a free account at learnnatively.com. Browse manga and books, check their difficulty level, and read reviews from other learners. As you finish books, you can rate their difficulty yourself and refine your profile. Natively is especially useful once you start reading native material in Stage 2 and beyond.

jiten.moe — Frequency Dictionaries

What it is: A site offering frequency-sorted word lists and pre-made Anki decks. Useful for targeted vocabulary building when you want to prepare for specific content.

How to use it: Visit jiten.moe and browse the available decks. You do not need anything from here right now — Kaishi 1.5k is sufficient for Stage 1 — but bookmark it. It becomes more relevant when you start mining vocabulary from specific shows or books later.

asbplayer — Subtitle-Based Learning

What it is: A browser-based tool that lets you load Japanese subtitles alongside anime or other video content, look up words with Yomitan directly from the subtitles, and create Anki cards from what you watch.

How to use it: You will get more use out of this tool once you reach Stage 2 and begin active anime study. For now, know that it exists and that it pairs powerfully with Yomitan.

AI Language Tools — A Brief Note

Large language models like Claude and ChatGPT can be useful supplements for language learning. At this stage, you do not need them — your tools above are sufficient. But as you progress, AI tools become genuinely helpful for getting grammar explanations in context, asking "why did this sentence use X instead of Y," getting writing corrections, and low-stakes conversation practice. Stage 4 has a dedicated chapter on AI-assisted immersion. For now, just know they exist and that they work best as a supplement to immersion, not a replacement — the same principle as Anki.

Now Close This Chapter

You have your tools. Yomitan is installed. Your vocabulary practice system is set up — productive recall and cloze cards, capped at a reasonable pace. You have a notebook for kanji. You know where to check difficulty ratings. That is everything you need. Do not spend another hour optimizing your setup. Go listen to something in Japanese.

Main Textbook Reference The main textbook's vocabulary and kanji sections align with the Kaishi 1.5k deck's most common words. Use both in parallel — textbook for structured learning, productive recall for retention, immersion for everything else.
