Green equities have skyrocketed in Japanese trading on Monday due to the expectation that Minister for Administrative Reform and Regulatory Reform Taro Kono becoming the nation's next prime minister, reports Bloomberg News.

Kono has previously voiced opposition to nuclear power, and although no one knows exactly how he would position himself upon becoming prime minister, private investors have seen this prospect as fine cause for boosting exposure the green sector. Renona, for instance, which runs solar and biomass plants, has appreciated by 15 percent. Also, photovoltaic company West Holdings closed trading hours up by 9 percent.

Here, purchase interest is largely pinned on speculation about who will replace current Japanese Prime Minister Yoshihide Suga, who plans to resign after holding the position for roughly one year.

The Liberal Democratic Party's internal election is set to take place on Sept. 29, and by virtue of its electoral dominance in Japanese Parliament, the party's leader is practically assured the PM role.

Polls this weekend show Kono topping the list of most favored candidates, and domestic media Nippon News Network also reports that Suga intends to endorse Kono as the new party leader.

Solar developer NPC's stock closed trading up 5 percent, and biomass company Erex's market value climbed almost 8 percent during the day.
