Questions & Answers about ashita no ryokou no shitaku o hayame ni shite okimasu.

How do I break this sentence down piece by piece?

A natural breakdown is:

• 明日 = tomorrow
• の = links nouns, like for / of
• 旅行 = trip, यात्रा? no, in Japanese just trip / travel
• の = another noun-linking of / for
• 支度（したく）= preparations, getting ready
• を = marks the direct object
• 早めに = a bit early / earlier than usual
• して = do in て-form
• おきます = do in advance / do beforehand

So the structure is basically:

[tomorrow’s trip] + [preparations] + early + do in advance

A smooth English translation is something like:

• I’ll get ready early for tomorrow’s trip.
• I’ll make preparations early for tomorrow’s trip.
• I’ll get everything ready ahead of time for tomorrow’s trip.

Why are there two の particles in this sentence?

Because Japanese often chains nouns together.

Here:

• 明日の旅行 = tomorrow’s trip
• 明日の旅行の支度 = preparations for tomorrow’s trip

So each の connects one noun to the next:

1. 明日 の 旅行
   trip of tomorrow → tomorrow’s trip

2. 旅行 の 支度
   trip’s preparations → preparations for the trip

Put together, it becomes:

• 明日の旅行の支度 = the preparations for tomorrow’s trip

This kind of noun stacking is very common in Japanese.
