Fortunes were mixed in Japan as consumer electronics giants Yamada Denki and Kojima announced their results for the first quarter ending June 30.

Revenue at Yamada Denki rose by just over ¥6bn (£38m) to reach ¥430.68bn (£2.7bn) for the quarter. Despite the rise in revenue, the retailer reported a slide in net profit in the first quarter, from ¥4.51bn (£23.8m) last year to ¥3.4bn (£21.5m) for the same period this year.

Rival Kojima, meanwhile, saw sales plummet by more than 11% to ¥97.66bn (£617m). Nevertheless, the company bounced into the black with a net profit of ¥112m (£700,000), compared with a loss in the same period last year.
