They say a good sign of fluency is being able to read a newspaper in a foreign language. This might be more true in a language where reading doesn't require the acquirement of thousands of unique characters, but it's still a nice benchmark to use for your Japanese.
I must admit - when I was living in Japan, I didn't read Japanese newspapers. They were available where I worked, but they were just too much for my feeble comprehension level. These days I still don't read the papers so much, but I do read online articles now and then. That's a lot easier due to the magic of cut and paste plus the availability of online dictionaries.
There is one section of one paper that frequently grabs my attention, however. Here at my office, we get a daily edition of the Nikkei (that is the Nihon Keizai Shinbun; 日本経済新聞). A lot of the articles are still beyond me, though I can generally understand what they're talking about. Every Saturday, however, there's a section called プラス1 (Plus 1), which usually contains tidbits about pop culture, food, fashion, etc. There are also often survey results, like the little piece I'm about to talk about.
I was looking at an old paper from October of 2014 and saw this neat little piece about requests spouses have for their partners. The article starts off by saying that it can be difficult to ask some things of one's spouse, but understanding what's in each other's heart can help to build a stronger relationship. Heh, perhaps.
With that in mind, a research arm of NTT conducted a survey asking married respondents what changes they would ask their spouses to make. The results are interesting, though perhaps some not so surprising. Let's have a look.
