Interesting question that deserves an answer. It's not a blog, but the television channel TV Japan is the best answer I can think of. My Japanese grandma loves this stuff and shows me her DVR recordings of it sometimes. The channel is mostly Japanese-language but some things are in English.
So yeah you get standard fare like NHK News and some movies/dramas/anime, but there are also some really nice daily-life programs. My grandma showed me stuff like a Japanese island populated with tons of cats that basically own the place, a subway lost-and-found desk and its back room so full of random crap it looks like department store warehouse, and a part of Tokyo with so many foreigners it's starting to feel like New York City. Also, there's another program called Cool Japan which keeps up on random stuff, anything from stationary shops to ridiculously real-looking sushi made from sugar.
https://en.wikipedia.org/wiki/TV_Japan shows the channel availability on various TV providers, you might have it already without realizing it.
