The headline refers to an increase in the popularity of the politician Koizumi within his party. Japan's well-known Nippon Television (NTV) has reported that among party members, Koizumi is emerging as a favored leader. Specifics about the survey or poll that led to this conclusion, and implications for any upcoming elections, would be detailed in the full article.

In Japan, the popularity among party members holds great significance as it often influences who leads the party and, thus, potentially the country. Public popularity can sway policy decisions, and an uptick in favorability can often result from a successful policy or strong leadership demonstration.

Similar to the U.S or EU, internal party popularity can forecast potential leaders. However, unlike many Western countries where popularity among the general public is more influential, in Japan, a leader's status within the party can often outweigh their public popularity.
