Great!
By you two standard. I can now claim to know all the Joyo kanji since I have read Japanese newspaper, even though I have no chance of passing Kanken 2.
Of course, reading newspaper is a more accurate test of one's Kanji ability than Kanji Kentei.
I never said that taking the test wasn't a BETTER way of testing a person's ability. But perhaps it would be good to consider how difficult those tests are.
The following information was collected from a tofugu.com article about the Kanji Kentei tests.
Kanji Kentei level 2 (there are 10 levels by the way, with 10 as the easiest and 1 as the hardest):
Covers all joyo kanji + the 284 kanji used in names.
You have to know on'yomi, kun'yomi, and stroke order
You have to be able to write them
You must be able to use them in sentences
You must know the names of the radicals
Must be able to identify antonyms
Must be able to identify synonyms
Must be able to differentiate between homonyms
You are tested on idiomatic expressions
You have to be able to read multiple-kanji compounds (up to about 4 characters in length)
Must know the radicals used to use a kanji dictionary
You are tested on special and unusual readings
You are tested on ateji
You are tested on complex radicals
And you are tested on special compound kanji words.
That is a ridiculous amount of information to have mastery over.
As I previously said, most Japanese people may not be able to detail all of this information, but in context, they will be able to recognize and read words which use them. The ability for Japanese people to write kanji is declining because of computers and cell phones, but they still tend to use the correct kanji because they can visually recognize it.
So okay, Japanese people probably "know" fewer than 2000 kanji in depth, but when it comes to reading (which is the whole point of written language), Japanese people can make use of several thousand kanji. I don't know all of the Latin/Greek/German/French etc. root words in English, yet I seem to be able to speak and read it quite well.
In my personal opinion, if you can read a newspaper or book in Japanese without having to constantly look up the kanji, then YES, you do know the joyo kanji. They have served their purpose as a writing system.
