Titty Twister is an SM and fetish bar in Kabukichō, Shinjuku, and part of the ARCADIA group, whose other venues are ARCADIA TOKYO in the same building and ARCADIA and ARCANA in Osaka. It describes itself as a variety SM bar where people with different interests meet and respect one another’s preferences. The profile of its master, the rope teacher and performer Otonawa, dates the bar’s opening to September 2016. Otonawa has studied under Hajime Kinoko since 2008 and debuted in a joint rope show with him in January 2009, and teaches for Kinoko’s school, Ichinawakai.
Otonawa-kai
The bar’s rope classes run under the name Otonawa-kai. In November 2026 its calendar listed two beginner and two intermediate evenings, each two hours long. Beginner classes need no booking; students who come without a partner practice with other students or on their own body, while the intermediate levels expect students to bring their own partner. The beginner sessions are taught by three of Otonawa’s students: one who began rope in 2021 and finished the Otonawa-kai intermediate course in 2023, one who started performing in 2024, and a staff member who has studied with Otonawa since 2019. Otonawa teaches the intermediate classes with two more of his students, one of whom passed the intermediate exam in 2017. The class pages say Otonawa has given workshops and shows in 20 cities in 11 countries and has taught more than 1,000 students. As listed in November 2026, a beginner class cost ¥6,000 and an intermediate class ¥7,000, models attended free, and people who stayed on at the bar afterward paid less than the regular rate.
Rope evenings
The bar also holds rope-themed nights. Nawa Biyori, scheduled for 21 November 2026, is a day given over to tying, aimed at guests who find it hard to ask someone to tie them or be tied; staff take part, guests who tie each other get ¥1,000 off the charge, and first-time partners are asked to agree their limits and a safeword beforehand. The bar opens Monday to Saturday evenings and is closed on Sundays and some Mondays.
