This paper deals with Seido Kikuchi and Rendo Ohashi, who seem to have taken over the network of art collectors of Seido. I primarily examine Kikuchi  Seido  Nikki and some rare materials kept by the Ohashi family to reveal the network of Seido in the early Showa era. As a result of my examination, I conclude that Seido had a close relationship with the group of art collectors led by Bokudo Inukai in the early Showa era.

  In addition, I identify two important points that will help to reveal the bigger picture of the network of art collectors in the period from the Xinhai Revolution to the end of World War II, a transitional period in the history of art collection. First, the activities of collectors between Japan and China after Luo Zhenyu's return to China need to be researched. Second, the roles of the collectors in the network who were contemporaries of Seido Kikuchi (Senro Kawai, Rokkyo Sugitani, Sentaro Yamaoka, Kyozan Yamamoto, Hekido Tanabe, Ginjiro Fujiwara and Tatsujiro Hashimoto), as well as the roles of the collectors who led the next generation (Kikujiro Takashima, Yasunosuke Ogiwara and Tsuneichi Inoue) and of those in China (Choji Sasaki and Shunzaburo Kuroki), need to be considered.

  The network of Seido included many Japanese art collectors other than those mentioned above, but few  points of contact between Chinese/Korean and Japanese art collectors, including their social relationships, have been confirmed; consequently, Chinese/Korean and Japanese art collectors are likely to have had separate networks. This fact will have to be taken into account when Chinese paintings, calligraphy and calligraphic rubbings are studied.
