In this paper, we mainly analyzed materials in the Naito Collection in Kansai University Library as part of Luo Zhenyu's research collection and examined the background of Luo Zhenyu's retreat to Kyoto to pursue his collection activities. We then further examined the Luo Zhenyu calligraphy, painting, and inscription rubbing collection (hereinafter the “Early Luo Zhenyu Collection”) and discussed the methods used to promote and sell them to Japanese collectors. As a result of the study, we found that Luo Zhenyu's decision to retreat to Kyoto was based on the arrangement by Fujita Kenpo, who determined that he would be able to raise the funds necessary to afford the expenses for the retreat and academic publishing. In fact, the initial cost of the Kyoto retreat was financed by the Uenobon Jushichijo. The sale of the Early Luo Zhenyu Collection also served to educate Japan about the reality of Ming and Qing calligraphy, paintings, and the good inscription rubbings and formed the core of the Ueno Yuchikusai and Onishi Kenzan collections. Yamamoto Jiho seemed to be inspired by such a movement and expanded the Ming and Qing calligraphy and paintings collection in a short period of time. Furthermore, the Luo Zhenyu collection was cataloged for sale in advance, and an exhibition of the collection was held. It should be noted that this later became a guideline for the collection group led by Inukai Bokudo in terms of methods of promotion and sale. In addition, we also found that Luo Zhenyu not only purchased the collection from Chinese collectors but also widely engaged in sales on their behalf and sales intermediation when the collection was transferred to the east. This suggests that a portion of the many calligraphy, paintings, and inscription rubbings released by the financially impoverished Qing imperial family and high-ranking officials flowed out through Luo Zhenyu to Japan, seeking a sales channel.
