Why I Created Tokyo Erotic Insider
Field notes on the side of Japan that lives after dark.
When I lived in a shared house in Japan, friends from overseas kept asking me the same kinds of questions about Japanese nightlife and adult entertainment.
They’d heard names like hostess club and girls’ bar, along with the many other kinds of adult venue Japan is known for — but they didn’t understand how the services differed, what to expect, or what unspoken rules and etiquette applied.
I saw the same confusion around adult products. At stores like Don Quijote, visitors could browse a huge range of Japanese adult goods, but it was rarely clear what each one was designed for, how they differed, or which ones suited beginners. People asked me directly, more than once.
Those questions pointed to something bigger. Japan’s adult culture is visible all over the world, but the context behind it usually isn’t. International readers can easily find explicit content, stereotypes, and sales-driven rankings. What’s genuinely hard to find is clear English writing that explains the culture, the laws, the etiquette, the privacy considerations, and what these products and services are actually for.
Who I Am — Sensei
I write under the name Sensei. Not a title I claim, but the role I kept ending up in — the person friends turned to when they wanted Japan’s night world explained honestly, without judgment and without a sales pitch. I keep my real name out of it on purpose: it lets me write candidly about a subject many people still treat as taboo, and it keeps the focus where it belongs — on the culture, not on me.
