Survey Puts Numbers on Japan's Sleep Cancel Slang
1An online survey released in Japan on Oct. 8 found that 58.1 percent of young people sleep six hours or less a night. The survey, timed for World Mental Health Day on Oct. 10, covered 203 people aged 15 to 29. It was carried out by an app company from Sept. 30 to Oct. 5.
2News reports linked the results to suimin cancel kaiwai, a slang phrase that has spread on social media. Kaiwai is used online to mean a group of people who share a habit. The phrase belongs to a family of cancel kaiwai terms that describe people who skip or put off everyday tasks. People in the sleep version cut their sleep to enjoy social media, videos and games.
3The most common answer was five to six hours a night, chosen by 46.8 percent. Only 36.9 percent said they sleep seven to eight hours. More than one in 10 reported sleeping four hours or less.
4Many of the young people said they would like to sleep more. About 44 percent said they cannot find the time, while 22.2 percent said they have trouble falling asleep. Around 15 percent said sleeping feels like a waste of time. In total, 31.0 percent tended to put being awake or other activities ahead of sleep.
5When they stayed up, 57.6 percent watched videos and 57.1 percent checked or posted on social media. Japan's health ministry suggests that junior high and high school students get about eight to 10 hours of sleep. The survey was small, so its results may not reflect all young people in Japan.

全文訳
110月8日に日本で発表されたネット調査で、若い人の58.1％が一晩の睡眠が6時間以下だとわかりました。10月10日の世界メンタルヘルスデーに合わせたこの調査は、15〜29歳の203人を対象にしました。調査は、あるアプリの会社が9月30日から10月5日にかけて行いました。
2ニュースは、この結果を、SNSで広まっている言葉「睡眠キャンセル界隈」と結びつけて伝えました。「界隈」は、ネットでは同じ習慣を持つ人たちの集まりという意味で使われます。この言葉は、毎日のことを省いたり後回しにしたりする人を表す「〇〇キャンセル界隈」という言葉の仲間です。睡眠版の人たちは、眠る時間を削ってSNSや動画、ゲームを楽しみます。
3いちばん多かった答えは一晩5〜6時間で、46.8％が選びました。7〜8時間眠ると答えたのは36.9％だけでした。10人に1人以上は、4時間以下だと答えました。
4若い人の多くは、もっと眠りたいと答えました。約44％は時間が取れないと答え、22.2％は寝つけないと答えました。約15％は、眠るのは時間がもったいないと感じると答えました。合わせて31.0％が、眠ることより起きている時間やほかのことを優先する傾向がありました。
5起きているとき、57.6％が動画を見て、57.1％がSNSを見たり投稿したりしていました。日本の厚生労働省は、中学生と高校生に8〜10時間くらいの睡眠をすすめています。この調査は小さいので、結果が日本の若い人全体に当てはまるとは限りません。
文法ポイント：過去分詞の後置修飾（名詞 + 過去分詞 ～）
過去分詞のかたまりが名詞を後ろから説明して「～された（名詞）」を表す。本文の An online survey released in Japan on Oct. 8 は「10月8日に日本で発表されたネット調査」、the most common answer ... chosen by 46.8 percent は「46.8％に選ばれた」。入試の長文で主語が長くなる形としてよく出る。
