There is usually no grammatical reason to use the article if the reference is to Japanese people in general, not to a specific group, even though it is sometimes used for reasons of sentence rhythm, for example. Japanese is an adjective in the collocation and people is a noun. The fact that Japanese refers to a nation is of no grammatical importance as far as the article is concerned. Similar collocations without an article:

Rich people have a lot of money.

Old people don't like to stand.

the Japanese = the people of Japan

The Japanese make excellent cars.

Yes, of course, but the original poster didn't ask about that. The + adjective usually produces a plural noun if the reference is to people: The Japanese make excellent cars. The young like different music than the old.

The deceased can be singular or plural: The deceased was/were buried yesterday.

My first reply: I've noticed the Japanese smile a lot.

The following complements the above reply.

the Japanese = the people of Japan

The Japanese make excellent cars.

The poster asked whether the artiicle 'the' is needed?

Am I not correct in my response to his query?

I get the impression that the poster is asking which is correct, Japanese people or the Japanese people. The Japanese isn't one of his options.
