Japan's largest discount retail chain, Don Don Donki, continues to pursue its policy of rapid global expansion amid the Covid-19 pandemic, one of the bright spots in an otherwise bleak retail landscape. This case study showcases Donki's unconventional business practices and unique marketing philosophy. The first section begins with an overview of the company, its current situation, and the competitive environment. The second section focuses on the major turning points that Donki has reached, addressing how Donki has responded to challenges with marketing and branding strategies and the results of its achievements. The third section details Donki's critical success factors. The fourth section describes the current challenges and potential recommendations to improve the company's business performance. Finally, the case study ends with a conclusion and valuable lessons learned from Donki. The discussion offers managerial and practical implications for business leaders and policymakers interested in running a business in Asian markets. It also serves as insightful teaching material for students to develop a deeper, multi-faceted understanding of a real-life application of a theoretical concept or solution.

Anti-Melanogenic Effect from Submerged Mycelial Cultures of Ganoderma weberianum
( Ying-jang Lai ),( Kai-di Hsu ),( Tzu-jung Huang ),( Chang-wei Hsieh ),( Yu-hin Chan ),( Kuan-chen Cheng ) 한국균학회 2019 Mycobiology Vol.47 No.1
Compounds from Lingzhi has been demonstrated the ability for inhibiting tyrosinase (a key enzyme in melanogenesis) activity. In this study, we investigated the anti-melanogenic activity from the submerged mycelial culture of Ganoderma weberianum and elucidated the skin lightening mechanism by B16-F10 murine melanoma cells. From the cellular context, several fractionated mycelium samples exhibited anti-melanogenic activity by reducing more than 40% extracellular melanin content of B16-F10 melanoma cells. In particular, the fractionated chloroform extract (CF-F3) inhibited both secreted and intracellular melanin with the lowest dosage (25ppm). Further analysis demonstrated that CF-F3 inhibited cellular tyrosinase activity without altering its protein expression. Taken together, our study has demonstrated that the chemical extracts from submerged mycelial culture of G. weberianum have the potential to serve as an alternative anti-melanogenic agent.
