According to TASAKI official website, TASAKI is a Japanese jewelry brand, with pearls and diamonds as the main elements to create a unique and elegant design. Tanaka Pearl has many specialty stores and department store counters in Japan, including Osaka's Hankyu Department Store, Daimaru Store and Shinsaibashi Store. However, there is no evidence that Tazaki Pearl has a specialty store or counter at Osaka Airport. If you want to buy pearls at Osaka Airport, you can consider other brands, such as Mikimoto, Yoko London and PASPALEY.
