As demands of consumers are getting more diverse, downtown and residential areas in Japan have changed to satisfy various image requirements, not just functional differences. It should not be overlooked that the activities of people who make, sell, and interact with their hobbies are growing to a non-negligible economic scale, with invisible change of landscape. In this research, through interview surveys at multiple exhibition spot sale meetings held in the Tokyo metropolitan area, we grasp the actual state of the hand-made craft market and the social background of their formation. We grasped the position of handmade craft market in chapter 2 and clarified the following three points.<br><br> 1) The system of the places for activities constituting the hand-made craft market of hobbies<br> The places for procurement of materials diversified in the real space and the Internet space, and they came to satisfy the quality, kindness, reasonable prices, convenience for the producers. Production of handmade crafts are enhanced by outside places and services such as shared workshops and the vendor services. In addition, the places for selling works has also diversified, with exhibitions and craft market services, the producers felt delighted that their work gained empathy with the purchasers and exchanges between artists and fans were born. These facts lead to their motivation for making. Almost all of the producers are using SNS to receive information and stimulated from works of other artists, and they also try to exhibit / advertise their works in SNS. It was found that the development of SNS supported the hand-made craft market, which have physical and non-physical places on the internet, crossing the process of materials procurement, production of handcrafts, and selling of their works.<br><br> 2) Types of hobby handmade craft market participants and their characters<br> Participants who started making their works and joined the handmade craft market could be classified into six types, and characters of each types are revealed, based on their motivations, sex, using of interest, working environment, school, occupation and so on. There are diverse participants, one purely enjoys making their works, while another one tries to sell their works, and some have activities for exhibitions and exchanges. It was found that these diverse participants with different purposes were gathered and formed a hand-made craft market.<br><br> 3) Space and social function of the places for making handcrafts, case study of shared studios<br> In the chapter 5, we targeted at the “share studio”, which is a new working model for handmade crafts. The share studio is a space that can be flexibly changed in layout according to the purpose of use, such as the installation of wheeled equipment, and it has the features that they are located in convenient places close to the station. We had investigation at three shared studios in Tokyo. They are not only providing a place for production but also a system of support for manufacturing of both hobbies and main businesses, while they are also providing a place for exchange of artists and information. They also have a role of expanding the base of monozukuri. They are widely used as a place of production for people who are hard to make their works in their own houses. These shared studios are established as a place to support "making things by yourself that is not by mass production".
