If you are planning to travel with friend(s) or family, those persons will each need to send an application form and payment, and become a WWOOF Japan member BEFORE Hosts are contacted. Please ENSURE you do NOT join WWOOF Japan, and then try to make plans to go WWOOFing with others who are themselves not yet WWOOF Japan members. Hosts will report such wrongdoing to the WWOOF office, which may result in your membership being blocked or cancelled, or render you on a blacklist. Most Hosts very reasonably say: "if a WWOOFer ignores rules relating to their membership application, it is likely they will likewise ignore the few rules I have at my place, and therefore I do not want them at my place". Penalties apply, as stated in the WWOOF rules. If you plan to go WWOOFIng with a child(ren), from 0 to 5 years membership is free. From 6 to 15 years, 2,750yen. All Child information must be provided in his or her guardian's application form.
