Questions & Answers about ashita no asagohan o yoru no uchi ni tsukutte oku.

Why is there a の in 明日の朝ご飯?

In 明日の朝ご飯, 明日 modifies 朝ご飯 through の.

So:

• 明日 = tomorrow
• 朝ご飯 = breakfast
• 明日の朝ご飯 = tomorrow’s breakfast

It does not mean tomorrow morning meal word-for-word in a strict English sense. It means the breakfast for tomorrow.

Japanese often uses の to connect nouns when one noun describes or belongs to another.

Why are there two の in 明日の朝ご飯を夜のうちに作っておく?

They are doing two separate jobs:

1. 明日 + の + 朝ご飯
   = tomorrow’s breakfast

2. 夜 + の + うち
   = during the night / while it is still night

So the sentence has two noun-linking phrases:

• 明日の朝ご飯
• 夜のうちに

This is very normal in Japanese.
