Questions & Answers about shizen no ooi machi ni sumetara, petto o katte iru hito mo shiawase darou to omoimasu.

Why is it 自然の多い町 and not 自然が多い町?

Both 自然の多い町 and 自然が多い町 are grammatically correct and mean roughly “a town with a lot of nature.”

• X の 多い N is a very common pattern:

  • 自然の多い町 = “a town rich in nature” / “nature-rich town”
  • 問題の多い会社 = “a company with many problems”
  • 人の少ない場所 = “a place with few people”

• X が 多い N treats X が多い as a relative clause:

  • 自然が多い町 = “a town where there is a lot of nature”

In everyday conversation, the nuance difference is tiny. 自然の多い町 may sound a bit more like a fixed description (“nature-rich town”), but both are fine and natural.

What exactly does 住めたら mean, and how is it different from 住んだら?

住めたら is:

• the potential form 住める (“can live”)
• in its past form 住めた
• plus the conditional 〜たら → 住めたら

So 住めたら ≒ もし住むことができたら = “if (I/we/etc.) could live (there).”

住んだら is just “if/when (I) live (there)” and doesn’t include the idea of ability or possibility.

Nuance:

• 自然の多い町に住めたら
  “If I were able to live in a town with lots of nature (if I had that opportunity / if that were possible)…”

• 自然の多い町に住んだら
  “If/when I live in a town with lots of nature…” (more neutral condition, less about whether it’s possible)

Here, the speaker is imagining a situation that may or may not be realistic, so the potential 住めたら is natural.
