Frequency lists can be deceptive. The word "Shinbun" (newspaper) appears very high in frequency lists because news articles repeat the word constantly. However, in daily conversation, you might use it rarely. Kaishi 15K balances "book frequency" with "anime/drama frequency," ensuring you learn words you will actually hear and use in real life.
Kaishi 15K (short for Kaishi 15,000) is a pre-made Anki deck containing roughly 15,000 Japanese words. It was created by a user named "Kaishi" and optimized based on frequency data and modern corpus linguistics.
Unlike older decks (such as the famous "Core 10k" series), Kaishi 15K is not just a raw dump of newspaper frequencies from the 1990s. It is curated to reflect modern Japanese usage, balancing frequency with actual utility for learners.
The deck utilizes a clean, minimalist card design. anki kaishi 15k
It avoids the clutter of example sentences on the front of the card, which can lead to "memory hacking" (guessing the word based on the sentence context rather than actually reading the Kanji).
The deck is ordered specifically to maximize efficiency:
Mistake #1: Treating it like a 15k deck. Do not try to "unlock" all 1,500 cards at once. Anki’s algorithm fails when you have 300 new cards pending. Be consistent. Frequency lists can be deceptive
Mistake #2: Ignoring pitch accent. Kaishi includes pitch graphs for a reason. Do not skip them. Spend 3 seconds per card looking at the pitch pattern. Your speaking will be unrecognizably better in 6 months.
Mistake #3: Not adjusting the template. The default card styling is beautiful, but you may want to move the audio button to the front or add a "notes" field. Learn basic Anki HTML/CSS – it takes 10 minutes.
Mistake #4: Relying solely on Kaishi for grammar. Vocabulary is useless without grammar. Use Tae Kim's Guide, Cure Dolly (YouTube), or Bunpro alongside the deck. Kaishi sentences are best understood with N5 grammar. It avoids the clutter of example sentences on
Anki Kaishi 15k (often stylized as Kaishi 1.5k) is a pre-made Anki deck designed to teach the most frequent 1,500 words in the Japanese language. Released in roughly 2022, it has rapidly become the "gold standard" for beginner-to-intermediate learners, effectively superseding older decks like Core 2k/6k.
Its rise to prominence is due to its modern formatting, optimized vocabulary selection based on recent corpus data, and compatibility with modern learning philosophies (Immersion-Based Learning). It serves as the foundational vocabulary bridge for learners moving from absolute beginner to consuming native content.
