The Ministry of International Trade and Industry will revise the call-sales law in a bid to curb fraudulent sales, ministry officials said.
The decision is in accordance with a proposal made Monday by a subcommittee of the Industrial Structural Council, which advises the MITI chief, they said.
The move was prompted by the increasing number of people victimized in fraudulent sales, especially through Internet advertisements or "spam" e-mail, they said.
Under one targeted method of fraudulent sales, job-seekers are coerced into buying personal computers or self-education materials at exorbitant prices.
MITI plans to submit a bill to revise the call-sales law possibly during an extraordinary Diet session to be convened Sept. 21 to regulate false advertising or multilevel merchandising, the officials said.
