四 in real context
四 is a N5-level word in Japanese meaning "four; 4" in this vocabulary set. Every word on LangOria comes with a real example sentence, so you meet 四 the way native speakers actually use it — not as an isolated dictionary entry, but inside a living Japanese sentence.
The example sentence for 四 is: "日本は四方を海に囲まれた国である。" (日本是个四面环海的国家。). Learning 四 through example sentences helps you internalize Japanese word order and collocations, so 四 is ready the first time you actually need it.
Add 四 to your N5 spaced-repetition review and it will resurface right before you are about to forget it — tomorrow, in three days, in a week. Combined with the rest of the Japanese N5 vocabulary set, a daily 45–65 minute loop is the fastest proven path from first exposure to confident, natural use of 四.
About Japanese N5
N5 is the entry-level tier of the Japanese Language Proficiency Test (JLPT) — the certification Japanese learners and employers actually recognise. N5 covers roughly 800 vocabulary words and 100 kanji, which is the minimum needed to read simple sentences, introduce yourself, and get by in everyday situations in Japan. Every word in LangOria's N5 deck is paired with kanji readings, an English translation, and a real example sentence from the Tatoeba corpus. Mastering N5 is the foundation for N4, N3, and beyond.
How to learn Japanese N5
Spend your first 3-4 months on N5. The 45–65-minute daily loop is enough — review the N5 deck with spaced repetition until your recall rate is above 90%, then start adding N4 vocabulary. Pair the deck with a structured textbook (Genki I or Minna no Nihongo) for grammar depth, and practice writing the kanji by hand at least once per day — handwriting builds character recognition that passive reading cannot. By the end of N5 you should be able to read simple Japanese sentences and hold a basic conversation.
Common questions about 四 in Japanese
What level is 四 in Japanese?
In LangOria's Japanese deck, 四 sits at the N5 level of the language's recognized ability ladder (CEFR for most languages, JLPT for Japanese, HSK for Chinese). At this level you learn 四 alongside the highest-frequency words you actually need.
How do I memorize 四?
Rote repetition rarely sticks on its own. Learn 四 inside its example sentence, say it out loud, and let spaced repetition bring it back at the right moments. The 45–65-minute daily loop is usually enough to anchor 四 in long-term memory.
Where does the example for 四 come from?
Every word — including 四 — carries a real example drawn from the community-built Tatoeba sentence corpus: sentences written by native speakers, not synthetic textbook filler. That context is what makes 四 memorable.
What should I learn after 四?
Cover the remaining words at the N5 level, then move up. LangOria schedules spaced reviews and frequency-ordered decks, so 四 reinforces the rest of your N5 Japanese vocabulary instead of standing alone.
