Questions & Answers about ryokou no junbi wa junchou ni susunde imasu node, anshin desu.

Why is の used in 旅行の準備?

の connects two nouns.

• 旅行 = trip, travel
• 準備 = preparation

So 旅行の準備 means the preparations for the trip or trip preparations.

This is a very common pattern in Japanese:

• 日本の文化 = Japanese culture / the culture of Japan
• 学校の先生 = school teacher / teacher at a school

Here, 旅行 tells us what kind of preparation it is.

Why is は used after 準備?

は marks 旅行の準備 as the topic of the sentence.

So the sentence is talking about as for the trip preparations...

This does not mean 準備 is the subject in exactly the same way English uses subjects. It means the speaker is setting up the topic and then saying something about it:

• 旅行の準備は = As for the trip preparations...
• 順調に進んでいます = they are progressing smoothly

Using は is very natural here because the sentence is about the state of the preparations.

What kind of word is 順調, and why does it become 順調に?
