I didn’t mean to imply that nobody tries in Japanese university, of course, especially since I have no first-hand experience. I’d just heard that the culture is, in general, less rigorous than in Western universities.
The point about networking through professors is really interesting to me. Alongside other replies about the intensity of the job hunt for Japanese students, it does sound like the system is geared as a bit of a ‘hiring pipeline’—to an extent at least.
Note: I skipped out on attending university altogether, so I don’t have a strong sense for the extent to which Western universities differ in these regards.
- The rigor in most Japanese universities is in the entrance exam. It's quite tough and is a decent filter for intelligence and study skills. STEM degrees in Japan can sometimes be rigorous as well.
- I would humbly argue that most US degrees (not sure about Europe) are not terribly rigorous outside of STEM fields and STEM-wannabe fields like economics. I have two degrees from two Ivy schools and many professors as friends, so I think I have a decent feel for who has to study hard to graduate and who doesn't.
- The schools are definitely a hiring pipeline, with the main factor being gaining admission. There are two problems with this. First, the average quality of entering students has fallen rapidly in the past 25 or so years. As such, a degree from any school not called Tokyo University has decreased in value and prestige by quite a bit. While a big Japan megacorp may have been willing to hire 20 graduates from a second-tier national university in 1985 (because they were high value-add individuals), they may only see 5 graduates in 2017 from the same school with the same level of value add. Second, there are just fewer salaryman jobs available today. As such, schools that used to be a strong part of the hiring pipeline are now only mariginal parts of the pipeline. Many parents and students are very frustrated by this. Japanese megacorps have started leaning much more on low-prestige temporary workers to replace the missing warm bodies that they are not hiring (compared to the past). These temp jobs are terrible for Japanese society since they are relatively low wage jobs with low stability and low prestige -- it's almost like not having a job other than the fact that you have to be at work. As I have said in another reply, I hope the youth of Japan get sick of this and rebel -- the older generation is massively screwing the younger generation in a gaping societal generational divide.
Most Japanese high schools are ridiculously easy to graduate from.
That said, most of the _competitive_ Japanese high schools -- that is, the ones who send their students to the best schools -- require quite a bit of work to graduate from. There is a reason for this.
High schools are divided into tracks in Japan via entrance exams, so the competitive high schools get students who are largely on board with rigorous study. Their goal is to crush the college entrance exam, and the best schools are quite good at test prep (and often go beyond test prep into "proper" learning of the topic). The students know they will have to work hard, and they mostly do. I humbly suggest that the students in these high schools work about as hard as high school students in the US who are trying to get into highly competitive universities.
That said, most high schools in Japan are not terribly competitive to enter and don't have high academic ambitions for their graduates (and that's totally ok). These students often have a lot of fun in high school, much like American high school students who are aiming at low competitive universities or no university.
Having said that, high level high schools in Japan have a bigger curriculum than what I was familiar with (in Canada). They will cover quite a lot of the stuff that you'd cover in first year university. However, I'll agree that it probably isn't that much different than what students voluntarily cover if they are trying to get into competitive universities in the US, for instance.
Finally, I'd like to echo that students in low level high schools in Japan generally have a lot of fun. It was probably the best atmosphere of any place I've ever worked. Obviously there are some students that are having problems, but the vast majority really enjoy this time. You can see it on their faces -- smiling all day long.
I'm not planning on having kids, but if I were, I wouldn't hesitate to put them into the Japanese school system. Personally, I love it. There are advantages and disadvantages, but as long as the parents aren't pushing their kids into places they don't want to go it offers a lot more opportunity, IMHO.
Just one last point, since it was raised above: employers do spend a lot of time training. I had a friend who graduated from a prestigious university as an engineer. She went to work at a fibre optics company. She spent the first 2 years there building cables and studying. The company wanted to make sure that she understood everything about the business from top to bottom. Now nearly 10 years later, she's managing an engineering group. Very different environment.
I think you mean "graduation rates", but I completely agree.
That said, there are some majors at elite schools that are very tough. The catch is that the enrollment in these majors/programs decreases rapidly as the weaker students change majors to something that is easier and/or requires less work.
