These are the notes found at the beginning of Sensei no Ojikan 05:

- <b>Burnt entirely white</b> can be thought of something similar to charcoal, where it turns white after being burned over an extended period of time.
- Hawaii, spelled backwards in Japanese is Iiwaha, but for your viewing pleasure, we've changed it to <b>Iiawah</b>, the way you'd spell Hawaii backwards in English.
- According to the <b>Japanese Labor Standards Act</b>, students are not generally allowed to work more than forty hours per week.
- A <b>Gugucci handbag</b> is a small parody of the famous Gucci handbags.
- Like many other words in Japanese, the word <b>shasei</b> is another one that has multiple meanings. In one context, as you’ll see later in the episode, it's referring to the <b>nature sketch excursion</b>, but in another, when Kudo is with Suetake, its meaning can be <b>ejaculation</b>.
- Marie-Henri Beyle, better known by his pen name <b>Stendhal</b>, is a French author born at Grenoble on the 23rd of January 1783. Stendhal is best known for his masterpieces Le Rouge et Le Noir (1830) and La Chartreuse De Parme (1839). Stendhal's subjects are often melodramatic, but they form a fascinating frame for his psychologically deep stories of selfishness and different paths towards self-discovery.
- <b>Ryuunosuke Akutagawa</b> was born in Tokyo on 1892. Akutagawa never wrote a full-length novel, but instead was a short-story writer, poet, and essayist. One of the first Japanese modernists to be translated into Englis, Akutagawa’s 'Rashomon' inspired Akira Kurosawa's classic film from 1950. In 1935, his friend Kikuchi Kan established the Akutagawa Prize, which is generally considered among the most prestigious Japanese literary awards for aspiring writers.
- Tsushima Shuji, also known as <b>Danzai Osamu</b>, was born in 1909. Danzai became ‘the literary voice of his generation’ and is known for works like Shayo (1947) and Ningen Shikkaku (1948).
