Encounter with a Cockroach

It was when I was leaving a fast food restaurant after I ate dinner, I found a cockroach in the outside.

It was very shocking to me.

I've never found cockroaches while living in Nagano Prefecture, and I met a cockroach for the first time in nine years.

For now, I've never found cockroach in my apartment, but my room doesn't clean very much.

I think that my kitchen is very clean (because I don't cook very much), but there are many cardboard boxes in my room.

Also, I heard that cockroaches like cardboard, and they often deposit their eggs in cardboard boxes.

In order to avoid cockroaches, I will do something with those cardboard boxes.

ゴキブリとの遭遇

昨夜、ファストフード店で夕食を食べて帰ろうとしたら、店の外でゴキブリを見つけました。

とても衝撃的でした。

長野県に住んでいたときは全く見なかったので、およそ9年ぶりにごきぶりと遭遇したことになります。

今のところ私のアパートにはまだゴキブリが出ていませんが、あまり綺麗でもありません。

私の部屋はキッチン回りは綺麗ですが（ほとんど料理をしないので）、ダンボールなどが多いです。

そしてゴキブリは、ダンボールが好きだそうで、ダンボール内に卵を産んだりするそうです。

ゴキブリが出ないように、しっかりと部屋をダンボールを片付けようと思います。

• It was when I was leaving a fast food restaurant after I ate dinner, I found a cockroach in the outside.
• I was leaving a fast food restaurant right after I ate dinner, and I saw a cockroach outside.

  I removed "it was" because it seemed un-needed.
  
  I corrected it to "right after" to show how quickly you would have spotted the cockroach, as if it were right outside the door.

• It was very shocking to me.
• This sentence is perfect! No correction needed!

• I've never found cockroaches while living in Nagano Prefecture, and I met a cockroach for the first time in nine years.
• I've never seen cockroaches while living in Nagano Prefecture, and today I saw a cockroach for the first time in nine years.

  I corrected it to saw a cockroach as I wasn't sure if you were actually MEETING a cockroach, as if it were in front of you, or saw as in it was crawling up a wall.

• For now, I've never found cockroach in my apartment, but my room doesn't clean very much.
• For now, I've never found cockroach in my apartment, but I don't clean my room much.

  I removed "my room doesn't clean very much," as your room isn't a thing that can clean itself. You're the one who would clean it.
