The organizers of the 2020 Tokyo Olympic and Paralympic Games and the Tokyo Metropolitan Government have begun inviting volunteers for the events.
Officials from both parties took to the streets of central Tokyo on Wednesday and distributed flyers to passersby.
Some people are raising concerns about treatment of the volunteers and conditions they have to meet.
A man in his 30s said a handout of around 9 dollars for traffic expenses to be given to the volunteers may be insufficient for people from outside Tokyo.
Officials say 110,000 volunteers will be needed for the games.
The organizing committee is inviting 80,000 volunteers to be directly involved in operations at event venues and the athletes' village.
The Tokyo Metropolitan Government is inviting around 20,000 people, in addition to those who already work as volunteers. They are to provide tourist information at airports, railway stations and other locations.
A senior official of the committee said they will provide information on the work more adequately.
Applications are to be accepted until early December.
