It shows that the second noun belongs to or is related to the first noun.
“の” is one of the most importantMeaning particles in Japanese because it allows you to build longer and more detailed sentences.
What You Can Express with “の”
• Possession (my book, her phone)
• Nationality description (Japanese student)
• Location/affiliation (school teacher)
• Multiple noun connections (my friend’s house)

※Long vowel note
You may wonder why 「とうきょう」 is written as “toukyou” in romaji but pronounced “tōkyō.”
In many cases, a long “o” sound is written using 「おう」 in hiragana.
