The annual cost of a Corporate Membership is ¥25,000, but there are four memberships in the corporate package. Corporate members are entitled to free attendance to monthly meetings and a 30% discount on workshop and other special events. Corporate members also get 50% off the guest price (¥1,000) for the first guest brought to a monthly meeting (you can bring more than one guest, but the others pay the full price). In addition, corporate members can display their logo on the top page of the TPC website and there is a website page set aside for Corporate members to describe their company capabilities.
