US Undergrad (Chinese Citizen) in CompE: Is a Japan Master’s worth it, or should I brave the US job market first?

Hi everyone,
I’m currently a sophomore undergraduate international student (Chinese citizen) in the US, majoring in Computer Engineering. I’m starting to map out my post-grad plans and would love some realistic perspectives on choosing between the US and Japan.

My Situation:
Background: I study at a large US public university with a very strong reputation in hardware and computer architecture (which is my main interest—specifically the intersection of hardware and software). My GPA is okay but not stellar (around 3.6).
Language: My English is fluent, but my Japanese is currently at zero. However, I am fully prepared to grind the language intensively. If I go to Japan for graduate school, I’d aim for English-taught Master's programs (like UTokyo).
Why Japan? Beyond the culture, safety and urban convenience, I am deeply invested in a specific niche Japanese entertainment subculture that has virtually no physical footprint in the US. Living near Tokyo/Yokohama would mean a massive boost to my personal well-being. I also deeply prefer the social boundaries and subtle communication style in Japan over the highly assertive culture in the US.

My Two Concrete Options:
Option 1: The Direct Route to Japan
Apply directly to English-taught Master's programs in Japan (e.g., UTokyo) right after undergrad. I would use the 2 years of grad school to pivot early, adapt to the society, and intensively grind my Japanese from zero to a professional/conversational level before hitting the local job market.
Option 2: The US Jumpstart
Stay at my current institution for a Master's degree, try to break into the US tech industry, and work there for 1–2 years to build strong technical depth, financial savings, and a big-name resume. After that, look for a lateral move, a internal transfer, or direct mid-career hire into Tokyo.

My Dilemma & Questions:
1 US Market Despair vs. Japan Master's: The current US tech job market for international New Grads is brutal. Many exceptionally talented seniors at my school are getting zero interviews. Because of this, I'm losing confidence in the "work in the US for 2 years then transfer to Japan" route. Would it be wiser to just pivot early and apply for a Japanese Master's degree directly?
2 Top-Tier Tech in Japan: My goal is to work exclusively for foreign tech companies (Woven, Google, NVIDIA, etc.) or top-tier globalized Japanese companies like Sony, focusing on architecture/systems. Given my US undergrad background, an English Master's from a top Japanese university, and conversational Japanese, how fiercely competitive are these specific slots?
3 The "No Way Back" Risk: As a Chinese national, if I commit to Japan right after undergrad, am I effectively closing the door on the US permanently? How difficult is it for an international student to pivot back to the US tech industry later in their career from Japan?
4 The Reality Check: For those who moved from the US tech/engineering ecosystem to Japan, what was your biggest "culture shock" or point of disillusionment? What are the things you miss most about the US that you didn't expect to miss?

I’m fortunate that my family can support my education financially, so I don't have immediate debt pressure, but I do want to be financially independent asap. I know Japan universities usually don’t offer fundings to grad students while my current university does.

Any candid advice, especially from international engineers who made a similar move, would be greatly appreciated. Thank you!
