Established in 2019, Cat Cafe MOCHA ARCHE Omiya brought the chain's experience to Saitama's premier shopping destination, positioning itself within the ARCHE mall complex. Located on the fifth floor of ARCHE, immediately accessible via the escalator, the location combines convenient shopping-district positioning with dedicated cat interaction space. The mall setting reflects MOCHA's strategic expansion into major retail hubs, making cat cafe experiences accessible to visitors combining shopping with extended relaxation. This Omiya location represents MOCHA's growing presence in suburban metropolitan areas, serving families and visitors from surrounding communities who might not otherwise access dedicated cat cafes.
The ARCHE Omiya location houses a diverse collection of cats representing numerous breeds including Munchkin, British Shorthair, American Shorthair, Maine Coon, Siberian, Chartreux, Exotic Longhair, Egyptian Mau, Persian, Kinkalow, Ragdoll, American Curl, Tonkinese, Scottish Fold, Exotic Shorthair, Somali, and Ragamuffin. Notable residents like Ciel (Maine Coon), Cloud (Siberian), and Kinpa (Kinkalow) exemplify the diverse personalities guests encounter. Reviewers emphasized the location's excellence as a work-focused destination, with one detailed visitor noting that they "came in during the day, the cats were sleepy and inactive" but "as the day went on, the cats started to become active and playful," demonstrating the value of extended visits. Multiple visitors highlighted that "staff took the time to have the cats interact with the customers which is nice for people who are shy around cats." The facility's design specifically supports varied activities—one reviewer praised "different kinds of seats so my back doesn't become sore from working in the same position making it easy to stay longer." Visitors noted the relaxing ambiance, with one describing it as a space to enjoy "珈琲を飲みながら漫画を読む" (drinking coffee while reading manga) "まったりゆったりとした時間" (in a leisurely, relaxed atmosphere) alongside the cats.
Operating daily from 10:00 to 21:00 (last entry 20:30), with closure on facility holidays, the ARCHE Omiya location charges ¥270 per 10 minutes on weekdays and ¥350 on weekends, with daily maximums of ¥3,600 (weekdays) or ¥4,200 (weekends). Children ages 6 and up are welcome with parental supervision. The facility includes complimentary drinks (tea, coffee, and vending machine beverages), phone charging stations, and manga reading materials. Cat treats cost ¥550 and are available in interactive format. Two daily feeding times occur at 10:30 and 19:00. Multiple reviewers highlighted the value proposition—one visitor noted comparison to Singapore pricing, finding MOCHA "reasonable." The diverse seating options (including comfortable couches) and comprehensive amenities make this location particularly attractive for work-from-cafe sessions. Staff are noted for their attentiveness to visitor comfort and cat welfare. As with all MOCHA locations, flash photography is prohibited, and visitors should allow cats to initiate contact rather than pursuing them.
