As the economy staggers under the weight of the strong yen, businesses in Japan are receiving much-needed offers of help, with a chance to reduce rent, pay fewer taxes and cut utility costs.

The problem is that these offers are coming from Japan's neighbors, particularly China. Delegations from across Asia have spent recent months hosting seminars in Tokyo's upscale hotels and conference rooms, hoping to pluck away Japanese business by offering incentives that companies find increasingly difficult to resist.

Since June, recruiters from at least seven Chinese provinces have hosted events in Japan. Vietnam came with a 20-member mission. Myanmar sent more than 300 representatives. One official from Zheziang Province in China described it as a "rare opportunity" to lure Japanese businesses that are strained by the rising yen, high corporate taxes and a shrinking domestic market.
