"conducted between March 27 and April 6" 

Interesting that the study was conducted in spring holidays. That should be somewhat taken into consideration, but ideally the time during the academic calendar, as in when students are at school, really needs to be included.

Also, you can't expect children, nor most adults for that matter, to responsibly manage their time. Structured hours and a routine are necessary ingredients to prevent the inevitable human inertia and addiction towards gaming, and the other war on us humans, the attention economy (i.e. time on the internet).

The economic climate in Japan is horrid. It should be no surprise they are only attracting people from poorer countries and regions. The number of residents from native English speaking countries has been declining rapidly over the last decade. This is because there is no money to be made in Japan. I’ve been living in Japan for nearly two decades and my current salary is 25% less than it was 15 years ago and I have a good salary compared to others. Add to this the costs of health insurance, city tax and that rip off pension they make people pay and Japan becomes a financial prison for foreigners. At present, over 80% of the public school ALTs in Tokyo are from non-English speaking countries with salaries ranging from ¥1.5-2M per year. It’s a joke! I’m leaving Japan next month and won’t be looking back.

The general theme of this is so on point.
