No links in feed_item nodes

I'm importing the following feed: http://www.japantoday.com/feed . In the feed itself, I can see that there is a <link> tag, but the nodes itself have no link in them to the original article.

Here is one of the imported nodes for reference: http://www.after-hours-japan.com/news/national-family-member-prioritized...

In the settings page, the input format is set as full HTML, and the 'Item URL' is mapped to URL.

Any thoughts?
