I would characterize the tenor of reports I saw on NHK earlier as "visible concern" on the part of the anchor and "restrained professionalism" on the part of their expert guests
I've said this before, though: Japan is a big country and it's diversity is often underappreciated. There is largely not a monolithic Japanese viewpoint on this. The same goes for just about everything. (See also: the United States.)
Were there not repeated cooling system failure resulting cooling pumps running on batteries (that needed to be swapped every few hours)? This sounds to me less like "something working as designed" and more like scraping last fallback options. Releasing (lightly radioactive) steam to ease the pressure in a chamber they have no view or control over doesn't sound that much better either. Nor does the evacuation of 140,000 people "from the area around Fukushima".
All in all, based on the quotes of Japanese authorities that sip into the Reuters' feed - they did not have a situation under full control at several points. They handled it as professional as it's possible, no doubts about it, but it could've unfolded differently.
That'll probably go up with Fukushima out of commission.
