Collocations

Mnemonic

Isshuukan (一週間) means "one week" — 一 (one) + 週 (week) + 間 (kan, duration). 間 marks duration in compounds: ichinenkan (a one-year span), ikkagetsukan (one month long), ichinichikan (one day long). The kanji 間 = 門 (gate) + 日 (sun) = "light coming through the gate" → "gap, interval, duration." Japan's vacation system: nenji yuukyuu kyuuka (annual paid leave) under labor law grants 10 days starting six months in and up to 20 days at 6.5 years tenure. Natsu yasumi (summer holidays) average 5–10 days; nenmatsu nenshi (year-end / New Year holidays) often run December 28 to January 4; Golden Week (late April to early May) chains Showa Day, Constitution Day, Greenery Day, and Children's Day into roughly seven days off. Japanese workers take only about 60 percent of their annual leave (versus Korea 80, Germany 95), though hatarakikata-kaikaku has been pushing improvement. JLPT N5 anchors isshuukan; the heijitsu / shuumatsu / kyuuka workplace cluster layers on top.
