"We have substantially improved our position in Japan which now represents a major part of our business"

This quote by David Milne recommends that the business he is connected with has actually made considerable development in the Japanese market. This development has actually led to Japan ending up being a major part of the business's company. This might indicate that the business has actually increased its presence in Japan, either through increased sales, increased market share, or increased brand name recognition. It could likewise suggest that the company has actually invested more resources into the Japanese market, such as opening brand-new offices or expanding existing ones. Whatever the case, it is clear that the company has made significant development in Japan and that it now plays a significant role in the company's overall service.
