Wen is scheduled to be in Tokyo for the May 21-22 trilateral summit with Japan and South Korea.
Vast areas of Japan's northeast region were destroyed by the March 11 disaster, which also set off one of the world's worst nuclear plant crises on the Fukushima prefecture which is yet to be stabilized.
Wen may visit Ofunato in Iwate prefecture, another badly hit region where a Chinese team was involved in rescue operations, or a shelter in Tochigi prefecture housing survivors of the disaster, Kyodo reported.
Earlier, China, concerned about radiation emissions from the Fukushima plant, had urged Japan to issue updates on the crisis promptly and take preventive steps quickly in the interest of its neighbors. The request was made by Wen in a telephone conversation with Japanese Prime Minister Naoto Kan.
Wen, while stressing his government's interest in promoting stable Sino-Japanese relations, asked Japan to strictly adhere to international laws, take preventive measures, and promptly and accurately inform China on the latest developments at the plant.
