About five or six years ago I was a member of a Japanese language and culture Meetup group. Once a month about five or six people would meet at a local chain restaurant for a couple of hours of Japan-related activities. One of those activities was reading through a couple of articles from NHK News Easy.
We would take turns, each reading a sentence and attempting to translate it. The group leader was fairly proficient, and would help the other members when words or sentences were hard to understand.
At the time, I had passed the JLPT N5, and had been studying (or, mostly ‘not studying’) Japanese for a number of years. I found that many or most of the sentences were difficult for me to understand.
Some of the difficulty was due to not knowing many kanji (I had made many attempts to learn kanji, but all of them had been ‘false starts’ - however I could read the furigana, which helped). Other difficulties involved unknown vocabulary (for example, there were lots of references to obscure Japanese government ministries, but there were also plenty of uncommon words including both verbs and nouns). A big difficulty for me was wrapping my brain around convoluted sentence structures and unknown grammar.
Fast forward a few years - I’ve been studying kanji on and off with WK, and at least by this point I’m no longer intimidated by kanji (even though I still have a long way to go as far as completing the WK journey), I’ve learned a lot more vocabulary, but I have not made very much progress in learning grammar.
I still find reading NHK News Easy to be ‘difficult’ - but without a doubt, it’s easier and more approachable than it used to be. I don’t read it every day, rather it’s more like one article a week. If I were to step things up and read it more often, I’m sure that it would help.
I’m reasonably sure that if I were to get my act together, restart WK, get through more of Genki II, and work at improving my reading comprehension by reading more level-appropriate content (such as on Natively), that reading NHK News Easy would become much less of a hurdle, and that it would help me in listening comprehension (when watching online news broadcasts).
FWIW, I do actually find a number of their articles to be at least “modestly interesting” - although many of them are not interesting at all (for example, reporting on economic or political trends or the latest actions by government ministries does not really grab my attention). I also find that many of the articles are unsatisfying both due to their brevity as well as their tendency to be very repetitive.
