I was not familiar with Japanese author Shunei Fujisawa, but the publication of some of his notebooks was a notable event in Japan.

Shuhei Fujisawa (1927-1997) recorded the deep sorrow he felt over the loss of his wife, Etsuko, in a pocketbook, excerpts of which his sole daughter, Nobuko Endo, has published in a magazine for the first time to mark the 20th anniversary of the prominent author’s death.
The words were written about 20 days after his first wife’s death at the age of 28, leaving an 8-month-old Endo behind.
Fujisawa’s writings in an unpublished pocketbook and three notebooks describe his dream of becoming an author, his passion for writing, and the deep grief over the loss of his wife.
The writings were penned from 1963, when Endo was born, through 1976, with the 13 years covering the period both before and after his first short story, “Kurai Umi”(Dark sea), was published.

What I found fascinating was the image of the notebooks themselves, which are from the 1960s and 1970s, but look almost exactly the same as Apica notebooks you can buy today! I had no idea those designs had stayed unchanged for so long…
