Working in Japan as a Project Manager Only to Find Out How Dreadful It Is

Six months in, and I still find no signs of hope in my own project.

First of all, members include: my boss and me.
My boss claimed to have all the knowledge surrounding developing a new business (I mean, he IS proving that with his current status), but he knows next to nothing in the technical aspects of developing a product for the market, which involves minds of international members in society beyond Japan. All he sees is Japanese news, Japanese media, and updates from closed Japanese-only communities. He loves to outsource, something that I find quite disagreeable at times.

First of all, he expects me to bridge the country I am from and Japan. To be honest, all I wanted was to work in peace, learn, and get used to making money.

To my horror and as expected, I've made zero yen contribution to this company. My boss accuses me in company sales meeting in front of everybody else that "the new project has not even started."

It made me furious. I have no members to manage, the developers are all busy with other projects, and I jumped in to code here and there (even though it is NOT in my job descriptions, and I have no clue how to code which made me start from zero), produced a website, a promotion video (even though the product for the consumers is still non-existent!!), and countless boss-only-on-demand power point presentations (which I hate; goddamn, who still uses powerpoint at this age?), only to get told "the new business has 0 users registered because it hasn't even started".

Why doesn't he try giving me the resources then? How does he expect to gain users if we don't build the project first? I understand he's a businessman at heart and that he doesn't develop projects, but I would like him to be aware that scolding me for studying programming due to lack of members doesn't justify his order to make me a project manager.

Japanese society and its human resource and human relation problems. I don't want to be a part of any of this anymore.
