Cat Cafe MOCHA Lounge Shinjuku

Opening in 2017, Cat Cafe MOCHA Lounge Shinjuku brought the expanded "Lounge" concept—featuring premium amenities and extended relaxation space—to Tokyo's bustling Shinjuku district. Located on the sixth floor of Shinjuku Pegasus Building on Shinjuku 3-31-5 (positioned across from Otsuka Furniture), the location offers an elevated refuge from one of Tokyo's most energetic neighborhoods. The Lounge designation, as with other MOCHA Lounge locations, restricts entry to middle school students and above, creating a mature, peaceful atmosphere suited to visitors seeking focused relaxation, work, or study alongside feline companionship. This positioning within the corporate headquarters building of Re Pot Co., Ltd. symbolizes MOCHA's central role in the company's mission.

The Shinjuku Lounge location hosts an extensive collection of over 30 carefully selected cats representing diverse breeds including Scottish Fold, Siberian, Munchkin, Ragdoll, Exotic Shorthair, Persian, Ragamuffin, American Curl, Maine Coon, Minuet, British Shorthair, Himalayan, Lamkin, Singapura, Selkirk Rex, Abyssinian, Tonkinese, Russian Blue, and Birman. Notable residents like Luna (Maine Coon), Howl (Norwegian Forest Cat), and Gauge (Siberian) exemplify the charm and personality guests encounter. Reviewers described the space as "BEAUTIFUL and full of gorgeous cats" with animals that "are all seem very well-cared for and friendly." One visitor noted the transformative power of the experience—"This was the perfect escape for all ages" with cats that "are beyond cute" and staff who are "super welcoming and nice." Multiple reviewers highlighted that "the cats will practically line up to be your best friend" when treats are purchased, while also noting that visiting off-peak hours reveals different behaviors—"During the evening leading up to dinner, the cats start gradually all waking up, starting to roam around looking for treats"—making each visit unique. The spacious layout accommodates various activities simultaneously without creating crowding, allowing visitors to read, study, play games, or simply observe sleeping cats peacefully.

Operating daily from 10:00 to 21:00 (last entry 20:30), the Shinjuku Lounge charges ¥270 per 10 minutes on weekdays and ¥350 on weekends, with daily maximums of ¥3,600 (weekdays) or ¥4,200 (weekends). The middle-school-and-up age requirement creates a distinctly mature environment. Complimentary beverages are included, available from vending machines offering coffee, tea, soda, and other options. Cat treats cost ¥550 and are described as transformative for interaction—visitors noted that "the cats LOVE them" and recommended making them a priority purchase. The facility features a modern, clean design with ample seating, video game consoles, books and manga for reading, and free phone charging. The sixth-floor location provides a peaceful remove from Shinjuku's street-level energy. Visitors arrive by removing shoes and placing all belongings in secure lockers, then receiving a timed receipt that tracks their visit duration. One detailed reviewer emphasized the professional check-in/check-out process and noted the importance of not losing the receipt for accurate time tracking. The facility is noted as having English signage and instructions available. As with all MOCHA locations, flash photography is prohibited, and visitors should respect cats' independence and autonomy by allowing them to initiate contact.
