In simple terms, my degree is in Japanese and Spanish language and culture. This means I’m not qualified to write much about sociology, psychology, physics, or statistics. Thus, I offer some possible research papers for people looking for ideas.
Game Center Physics: Gravity, Friction, and Other Factors that Keep People P(l)aying
Umbrella Theft: The Psychology of Rainy-Day Petty Crime
Tachiyomi: Condoned Loitering
Priority, Courtesy, and Alacrity: A Study of Train Seating Convention
Xenophobia vs. Allophilia in the Tokyo Metropolis
Japanese Language and the Slow Influx of English
Maid Cafés, Pachinko Parlors, and Host Clubs: Japan’s Niche Nightlife
… you’re welcome. I expect at least footnote credit.
