Masudaen Sohonten is a traditional green tea shop in Asakusa, Taitō-ku, Tokyo, located at 1-1-17 Asakusa, just a 1-minute walk from Asakusa Station exits. The shop is halal-friendly, offering halal-certified soft serve ice cream and green tea products, so Muslim travellers can safely enjoy matcha, hojicha, and tea desserts. Recommended items include their matcha + vanilla soft serve and a variety of high-quality tea leaves (matcha, roasted teas), which also make excellent souvenirs. The vibe is historic and calming, with a rustic shop frontage, warm staffing, and a nostalgic Japanese ambience—great for relaxing while exploring Senso-ji and surrounding streets.
