Japanese to English

するが (suruga) may be used to mean "I'll do it, but..." in Japanese.

Example: するが、好きじゃないですよ (suru ga, suki janai desu yo) - "I'll do it, but I'm not going to like it!"

Perfect.

硫黄島 or Iwo Jima (However, it should be properly transliterated from Japanese as "Iōjima") when translated literally means "Sulphur Island".

It's very interesting the first time you hear the proper pronunciation since we're accustomed to saying the 'w' when in actuality there is a long 'o' instead. As the previous poster wrote, it's said いおうじま ioujima。

"Omote", written 面, means face, surface, or mask.

Dialect, like Kansai-ben!

It means "My first" or "My number one"

Yes

It's a simple ratio.

Seeing as there is no character for 'k' in the Japanese language, I will assume you are talking about 'gyaku', which means reverse/opposite.

One mo' time.

This means "[You] are good at [something]!"

It means Euglena. I think.

"toda" means absolutely nothing unless you mean "touda" (pitching and batting).

'Little sister.'

That was very skillful!

konnichiwa is hello in japanese

tamashii

It can be translated as "I'll hang out with you again."

This translates to "who is in that room over there?"

"Chestnut."

I meant yubiwa which means ring. Therefore, it means how much is the ring?

夜の暗殺者 /yo ru no an sat su sha/ in Japanese means 'Assassin of the Night'.

The sentence 私はあなたがいないので、大変寂しい (watashi wa anata ga inai node, taihen sabishii) would be translated as "I'm incredibly lonely because you're not here".
