Free consultation is available in each prefecture, the National Association of Real Estate Agents, and the All Japan Real Estate Association, so please consult with them.
If you have participated in an online seminar from outside of Japan and the pushy sales continue even after you have refused to be solicited, you may be able to consult with other real estate brokerage companies that provide second opinion services to customers outside of Japan.
The act of the real estate brokerage company continuing the solicitation of the purchase is a prohibited act in the law concerning the real estate dealings, though the customer showed the real estate brokerage company the intention of not wishing to receive the solicitation of the purchase continuously as the intention of not concluding the sales contract.
