Japanese Title: 「草迷宮」　-　「Kusa Meikyū」
Kusa in Japanese means grass. The kanji that makes up the word kusa is the first character of Motoko's family name, 草薙素子 or Kusanagi Motoko. Similar to the word anime being short for animation, Japanese words can be abbreviated in this manner because the meaning of the kanji is implied. Another example is the Japanese title for episode 7 of 2nd GIG, "PU239/94". The first word of the title, 狂想, is kyōsō, which does not actually mean rhapsody as it translates to fantasy. Attaching 曲 to the word makes it kyōsōkyoku, which does mean rhapsody. In this instance, kyoku has been left off in order to give kyōsō a double meaning. It can mean fantasy and rhapsody.

Batou is drinking a beer labelled 激 or Geki which means 'Mighty'.

Kanji on bridge: 水上パス (Suijō Pass) - Waterway Pass. A more common name in English would be 'Pedestrian Bridge'.

The shop that Motoko visits is called 牢記物店 or Rōki Mono Tana. Literally, the translation is Memory Object Shop, but a better translation would be Nostalgia Shop.

Cyborgs and Alcohol: Ghost in the Shell
Togusa's explanation of a cyborg's ability to consume alcohol without getting drunk echoes the words spoken by Motoko in the boat scene with Batou in Mamoru Oshii's 1995 movie Ghost in the Shell.
