​【Description】

This album was originally a small notebook cherished by Hideki Yukawa, recording moments of exchange with family members and close friends. Entries note dates, locations, and brief inscriptions, and reveal how the participants responded to one another through Chinese poetry, waka, painting, and calligraphy. The individuals whose traces appear in the album belong primarily to the following three families:
 

i. The Ogawa family:
Takuji Ogawa (father); Yoshiki Ogawa (elder brother); Shigeki Kaizuka (second elder brother; originally surnamed Ogawa); Tamaki Ogawa (fourth younger brother); and Taeko Ogawa (second elder sister).

ii. The Yukawa family:
Seiyō Yukawa (b. 1891; Hideki Yukawa’s brother-in-law and a physician); Kyōko Yamamoto (wife of Seiyō Yukawa, who served as a prosecutor at the Great Court of Cassation); and Toshiko Yukawa (eldest daughter of Seiyō Yukawa).

iii. The Nakaya family:
Ukichiro Nakaya (physicist); Shizuko Nakaya (née Teragaki, Nakaya’s second wife); and Fuyuko Nakaya (Nakaya’s younger sister).

In addition, scholars such as Hiroo Kumagai (1911–1977; originally surnamed Aoki), a physicist, also left records in the album.
