How do these elements work in this sentence?

Question

for full context: http://www3.nhk.or.jp/news/easy/k10011218521000/k10011218521000.html

the sentence in question: このため、東京や大阪、京都以外にも泊まる人が増えるように、いろいろな観光地を紹介していくことにしています。

My attempt at translation:

"To achieve this (or: because of that?), it was decided that they (will?) present various tourist attractions, except for tokyo, oosaka and kyoto, so that the number of people taking sleepovers increases."

First, I translated both ように and ため in a final sense ("they did X, so that..."/"...in order to..." etc.). In previous questions about ように it often happened that ように didn't represent this, but here I wouldn't know which else case could apply. It seems odd though that there are two final clauses "sandwiched" into this sentence.^^

Second, 東京や大阪、京都 by itself is already a bit confusing, because first there is a connective や, and then 京都 follows without any particle. I guess it belongs to the other two, however, I'm not sure because I didn't encounter this case so far and I could also imagine that concerning 以外, maybe 京都 alone is the exception. However, in thise case I wouldn't know how to implement the other two 東京や大阪 because there wouldn't be any particle embedding them into the syntax of the sentence.

And finally, is 紹介する used in the meaning of some form of publicity/marketing?

Answer 1

Your translation attempt is okay except for the 東京や大阪、京都以外にも part. Don't ignore に and も. It adverbially modifies 泊まる and means "(to put up) also in places other than Tokyo, Osaka or Kyoto." Your translation would be much more natural just by moving this part right after "sleepover".

「東京や大阪、京都」 is a natural way to list things in Japanese. It could have been 「東京、大阪や京都」 (like you say this in English) or 「東京や大阪や京都」 (although this looks slightly clumsy). After all, the usage of comma is less strict in Japanese, as you may already know.

Your understanding of ように is perfect. It means "so that ～" or "in order to ～" here.

I think this このため is closer to "because of this", and can be simply translated as "Therefore."

Oh, where did "health" come from? Check the meaning of 観光地.

Answer 2

You're right that this このため is "in order to achieve [the increase in accommodations discussed in the previous sentence]".

東京や大阪、京都以外にも泊まる人

"People staying outside places like Tokyo, Osaka, and Kyoto..."

が増えるように

"...in order to increase [the number of those people]..."

いろいろな観光地を紹介していくことにしています。

"...we have decided to continue introducing various tourist attractions."

There is no mention of "health resorts." Perhaps you were confusing "観光" and "健康"?
