TOKYO, Nov 16 (Reuters) - Japan's Nikkei stock average edged up 0.2 percent on Monday, buoyed by retailers and other defensive shares, but weighed by banks and companies such as Hitachi Ltd (6501.T: Quote, Profile, Research) that sank on fundraising concerns. Hitachi, Japan's biggest electronics firm by sales, fell 8.5 percent after saying it will raise up to $4.6 billion to shore up its capital, joining a scrum of Japanese firms tapping equity markets before a possible economic slowdown.
