の (NO) is used to express possession, often used to translate "my, your, his, her," etc.

The particle の (NO) is used very often in Japanese to provide further information about something. の links the two elements using this structure: "Additional information + の + main element."

Depending on the sentence, the nature of the additional information varies. Here are several examples:

Attribute, property of an object

• Plaid coat
  チェックのコート (chekku no kooto)
• Green plate
  緑色のお皿 (midori iro no osara)

Function, usage

• Cinema ticket (= for the cinema) 
  映画のチケット (eiga no chiketto)
• DIY tools
  日曜大工の道具 (nichiyou daiku no dougu)

Geographical position

• Churches in Germany
  ドイツの教会 (Doitsu no kyoukai)
• Japanese inn in Kyoto
  京都の旅館 (Kyouto no ryokan)

Temporal information

• The summer in two years
  再来年の夏 (sarainen no natsu)
• The old currency
  昔のお金 (mukashi no okane)

Material

• Leather gloves
  革の手袋 (kawa no tebukuro)
• A wooden shelf
  木の棚 (ki no tana)

The particle の (NO) can appear in a structure expressing position and location. Examples:

• ... の上に (NO UE NI) : on
• ... の中に (NO NAKA NI) : in
• etc.

の (NO) is used when a noun follows another noun, and when both grouped together express the same thing.

"Friend" and "Hanako" express the same idea (Hanako is my friend = my friend is Hanako).

の (NO) expresses the idea that something belongs to a category.

The particle が (GA) is used to indicate the subject in the sentence (not only). It can be replaced by の (NO) to form complex sentences with several clauses. This structure is often used to build sentences using "THAT". Mastering this usage of の is important to progress.
