幾人も or 一杯? Kanji or hiragana?


I am writing the following sentence:

サン・パウロに日本人がいっぱいいるから。。。よかったですね！

And I'd like to know if 幾人も could be a more respectful/more natural
replacement for 一杯, and whether I should be using kanji.




> 「サン・パウロ **に** 日本人がいっぱいいるから。。。よかったですね！」

This sentence is OK. The only thing I would change to make it more natural
would be the 「に」. Using 「には」 would make it far more natural.

> And I'd like to know if 幾人{いくにん}も could be a more respectful/more natural
> replacement for 一杯{いっぱい}, and whether I should be using kanji.

Using 「幾人も」 in this context would be a bad idea. Why? Because it only means
"many" mostly when the number is a dozen or two **_at the most_**. São Paulo
has about a million Japanese and Japanese Brazilians, correct? That is
definitely **_way_** too many to call 幾人も.

I would not worry about writing 「いっぱい」 using kanji. Your sentence is already
very informal with the use of 「から」 and 「よかったですね！」. 「から」 is more informal than
many J-learners seem to think.
