Kanji cards that don't insult your intelligence

The most challenging part of Japanese is learning the 2136 Kanji characters one needs to be fluent. While it sounds like way too many characters, spaced repetition makes it possible to learn them efficiently.

But, in most resources, spaced repetition is synonymous with brute-forcing all Kanji into your brain with silly mnemonics.

Kanjideck is better. No silly mnemonics. A deck of cards tailored for understanding, not memorizing, with spaced repetition. Each Kanji can be immediately useful through verb and adjective readings, and compound examples which only use Kanji you've already seen. That, colored radicals, and etymological hints, make remembering and learning much easier.

How to study with Kanjideck

Put simply, studying Japanese using Kanjideck follows three simple steps:

Review cards you’ve already learned, according to the schedule,
And learn a couple of new cards (3-5),
Every day.

To review a card, pick it up with the colored side facing towards you and try to actively recall, from the Kanji in the center, its meanings and at least one of its readings. Then, practice conjugating verbs, adjectives, and examples.

Example

The kanji 「話」has meanings “tale, talk”.

The compound word「電話」is formed by the kanji for “electricity” (電) and the one for “talk” (話), and it means “telephone call”.

And the reading of 「話」with the trailing「す」hiragana character is the verb “to talk” 「話す」. The polite conjugation is 「話します」.

Studying each card means, foundationally, to learn the kanji in that card, but it also means to practice these many aspects of Japanese to contextualize the kanji while improving your fluency overall.
