Definition:
KameSame is a free, web-based Japanese spaced repetition application that drills English → Japanese vocabulary recall — the reverse direction of most SRS tools. Where WaniKani, Anki recognition cards, and most vocabulary apps test whether a learner can identify the Japanese word’s meaning when they see it, KameSame tests whether the learner can produce the Japanese word when they only see the English meaning. This active production mode builds a different — and often underdeveloped — side of vocabulary knowledge. KameSame is frequently used as a companion to WaniKani to cover the production gap that WaniKani’s recognition-only format leaves.
In-Depth Explanation
Vocabulary knowledge has two sides: receptive knowledge (recognizing a word when you encounter it in reading or listening) and productive knowledge (being able to produce the word yourself when speaking or writing). Most Japanese SRS tools default to receptive drills — show the Japanese, recall the English. KameSame deliberately targets the productive side.
How It Works
A KameSame review session presents an English meaning and asks the learner to type the corresponding Japanese word — either in hiragana, katakana, kanji, or a combination, depending on the word. The system accepts multiple valid answers (a word with both kanji and kana forms, for example) and uses a Japanese IME-compatible input field so learners type in the same way they would in real Japanese contexts.
Reviews are scheduled using standard SRS logic: words answered correctly are spaced further apart; words answered incorrectly are pushed back into frequent review rotation.
WaniKani Integration
KameSame has built-in WaniKani API integration. Learners who use WaniKani can connect their accounts and automatically load every vocabulary item they’ve unlocked in WaniKani into KameSame — so they’re drilling the English → Japanese reverse of exactly the same items WaniKani is teaching them Japanese → English. This pairing covers both directions of the same vocabulary set without duplication.
Vocabulary Sources
Beyond WaniKani integration, learners can add vocabulary to KameSame from:
- Custom word lists — manually add any Japanese vocabulary
- Pre-built JLPT lists — N5 through N1 vocabulary
- Community-shared lists
Why Production Matters
The production deficit is well documented in vocabulary acquisition research: learners who study only receptive vocabulary often find themselves unable to retrieve words actively when speaking or writing, even for items they recognize instantly in reading. This asymmetry is especially pronounced in Japanese, where learners frequently can read kanji compounds they couldn’t produce from memory. KameSame’s reverse-direction drills directly address this gap.
History
- KameSame was created as a community project to fill the production-recall gap left by WaniKani’s recognition-only format.
- The app is free, web-based, and has no paid tier — sustained by community support.
- It gained adoption through the WaniKani forums and Japanese learning communities who recognized the complementary role it plays alongside recognition-based tools.
Common Misconceptions
“KameSame replaces WaniKani.”
KameSame is a companion tool, not a replacement. It does not teach vocabulary from scratch — it assumes learners have already encountered and begun learning the vocabulary through another method (typically WaniKani or a similar tool). KameSame’s value is in adding the production direction to vocabulary items already partially learned.
“Testing English → Japanese isn’t useful for Japanese learners.”
While real Japanese output draws on a variety of cues (not just English translation), English-to-Japanese production drills build retrieval strength for vocabulary that receptive recognition alone does not. Learners who want to speak or write Japanese need to be able to access words from meaning, not just identify meaning from form. KameSame trains this direction explicitly.
Social Media Sentiment
- r/LearnJapanese: Recommended specifically in discussions about WaniKani limitations. Standard framing: “WaniKani + KameSame covers both directions.” Appreciated as free and low-overhead.
- WaniKani community forums: Mentioned positively as a production complement; links to KameSame appear in many “maximize WaniKani” guides.
- Discord Japanese servers: Niche but consistent presence in vocabulary-focused channels.

Summary: Shows that productive study produces stronger vocabulary knowledge than receptive-only study — directly supporting KameSame’s English-to-Japanese production approach.
