Japanese companies are targeting China's e-commerce platforms to expand their sales as they struggle with a sluggish domestic economy. The effort is expected to increase as Chinese shoppers continue to snap up Japanese goods on line.

Japanese drugstore and pharmacy company Kirindo opened its online shop on Tmall.com in 2011. Sales have since continued to rise at a higher than expected rate.

"The main business of our company currently is real stores. But we'll focus on e-commerce in the future. We'll let the administration and employees realize the importance of China's e-commerce, and ally with other companies to advance the strategy," said online sales dept. director of Kirindo.

Electronics manufacturer Casio is even developing products customized for Chinese consumers thanks to its good performance in China's markets.

"We believe the Chinese market is very huge and developing fast. Many consumers have high demand for high-tech products. So we'll continuously develop more products to meet the demand," overseas operation dept. director of Casio Computer Co., Ltd.

Alibaba announced plans to launch a Japanese merchandising center last week and nearly 200 companies from Japan expressed interest in joining.

It's expected that Chinese consumers will buy more and more Japanese goods as additional businesses from Japan enter China's e-commerce sector.
