The set price is ¥1,000 per set of four cards (individual cards cannot be purchased). Orders can also be placed by phone (Biotec main line: 03-3511-9711) or email (shigyo_collection@biotec1984.co.jp.

Haru (Spring): Yasuda Yukihiko’s Painting “Ako Eishi (Ako chants a Poem)”

Haru (Spring): Yasuda Yukihiko’s Painting
“Ako Eishi (Ako chants a Poem)”


 This beautiful work depicts Ako (the childhood name of Sugawara no Michizane) chanting under a white plum tree on a moonlit night, portraying Michizane’s childhood. “Getsuya Baika o Miru” (meaning: The moon shines like snow, and plum blossoms appear like shining stars. Ah the full moon traverses the sky, and the garden is filled with the fragrant scent of plum blossoms.) This scene depicts him composing this Chinese poetry at the tender age of eleven. Perfect for the New Year, it also serves as an auspicious symbol for scholarly endeavors throughout the year, suitable for use any season.

Natsu (Summer): Yasuda Yukihiko’s Painting “Yatsuhashi”

Natsu (Summer): Yasuda Yukihiko’s Painting “Yatsuhashi”


 This work depicts the famous scene from [Ise Monogatari (The Tales of Ise)] where Ariwara no Narihira, traveling east from Kyoto, arrives at “Yatsuhashi” in Mikawa Province (around present-day Chiryū City, Aichi Prefecture), where kakitsubata (irises) bloom beautifully. Impressed by the irises, Narihira composed the waka poem beginning with the word “kakitsubata (irisis)” : “Karagoromo kitsutsu nare ni shi tsumashi areba harubaru kinuru tabi o shizo omou” (Now that I’m used to wearing these clothes, I think back to the long journey I had made). The deep ultramarine of the irises and Narihira’s blue robe evoke the refreshing breeze of early summer in this work.

Aki (Autumn): Yasuda Yukihiko’s “Kaki (Persimmons)”

Aki (Autumn): Yasuda Yukihiko’s “Kaki (Persimmons)”


 This work depicts persimmons with a powerful presence, also featured on the cover of Nakayama Yoshihide’s novel “Bashoan Tosei” (Chuo Koronsha, paperback edition), which chronicles the life of Matsuo Basho. It is well known that Yasuda Yukihiko cherished grasses, trees, flowers, and plants, and his garden at his home in Oiso became a “small plum grove” where plum blossoms flourished. He also frequently painted fruits he ate daily and seasonal ingredients. While he made several sketches using persimmons as motifs, this particular work is one he completed with thorough coloring. Why not write a letter on this postcard during the long autumn nights?

Fuyu (Winter): Yasuda Yukihiko’s “Farewell at Yoshino”

Fuyu (Winter): Yasuda Yukihiko’s “Farewell at Yoshino”


 This depicts the famous, heart-wrenching scene of the final farewell between the lord, Minamoto no Yoshitsune, and his retainer, Sato Tadanobu, at Mount Yoshino. Yoshitsune had incurred the resentment of Yoritomo and was hiding at Mount Yoshino with Shizuka Gozen and his vassals. Soon, they were pursued by enemy monks-soldiers. Tadanobu, wearing Yoshitsune’s helmet as a decoy, held them off while Yoshitsune escaped northeast. This scene on Mount Yoshino, where master and retainer part amidst flurries of snow, is a heart-wrenching depiction of the ultimate expression of Bushido. It conveys the spirit of Bushido regardless of season.

Announcement of Publication and Commemorative Event for “Tamashii no Nensyo e (To the Combustion of the Soul): Expanded Definitive Edition” (by the late Shimizu Katsuyoshi and Shigyo Sosyu, published by Jitsugyo no Nihon Sha).

 The book “To the Combustion of the Soul” (Jitsugyo no Nihon Sha), compiling conversations between the late Shimizu Katsuyoshi, Shop Manager of Dokusyo no Susume, and Shigyo Sosyu will be published as an expanded definitive edition, including a dialogue between the two held in Shinozaki, Edogawa Ward in 2023. Originally published in 2015, the book had been out of print for a long time, with requests for its reprinting coming from various quarters. Furthermore, as 2025 marks the 30th anniversary of the Dokusho no Susume’s founding, this expanded definitive edition will also serve as a commemorative publication.

 However, to our regret, Mr. Shimizu Katsuyoshi passed away just before publication (June 2025), making this his final work. We sincerely hope that this book, which embodies Mr. Shimizu’s way of life leading the useless reading, and the reading to live life to the fullest as his final message, will inspire you to pick it up and reflect on the act of reading itself.

 This time, the exhibition titled “Memento of the Wind―New・Collection―”(Period: Apr.01,2025~July 19, 2025) will be the first public viewing of the newest addition to Shigyo Sosyu Collection. The main focus will be on artworks such as Western-style painter Hirose Ko and sculptor Sawada Hideo, who Shigyo Sosyu has collected many artworks in recent years that he sees as symbolic of Divinity and futuristic art. Also, the past collection will be displayed in combination. We hope to have you sense the transformation of the divinity inherited along with the new wind of “Memento of the Wind.”


 In addition, ARTIS No.34, to be published on April 01, will have the same theme as the exhibition, “Memento of the Wind,” in which Shigyo Sosyu will speak about the Divinity expression suitable for the new era. In addition, [Opening Page] features『Ringo saku koro (When Apples bloom)』by Hirose Ko, and [Free Project] Here and Now: summarizes Sawada Hideo’s work. In [Contribution] My Eye: Dr. Fukushi Tsugumi, a medical doctor engaged in research on interstitial gels, wrote an invigorating essay on the Gassan sword, linking it to the second law of thermodynamics. We hope you will take it in your hands.

On Feb.01, 2025, the 33rd issue of “ARTIS” (bimonthly), a periodical booklet on culture and art, will be published.

 On February 1, the 33rd issue of “ARTIS” (Latin for “art”), which introduces our gallery’s collection from various perspectives and has been well received by our readers, will be published. This issue, titled “Seinaru mono e (Toward the Sacred),” will explore the sacredness manifested in art. In an interview with the director Shigyo Sosyu, he narrates extensively about the historical transition of the “sacred” and new art forms for the future.

 The opening painting, “Ao Fuji (Blue Fuji),” by Ms. Matsui Yuka, explores the mystery and depth hidden in the work.
 In [My Eyes] corner, which features contributions from visitors to the museum, aesthetician Mr. Hirai Michiyuki has contributed a poetic art criticism essay exploring knowledge and beauty, in response to a photograph by Mr. Tachihara Sei. We hope you will take a look at it.

 At Shigyo Sosyu Collection/ Memorial Gallery of Toshima Yasumasa, exhibition “Sword and Flower” exhibition (~Mar. 22, 2025), which has been visited by many visitors, continues to be on view. Every month, the exhibited works without glass cases will be replaced, so we hope you will enjoy the different works. The exhibition features swords by Gassan Sadatoshi of the Gassan family of swordsmiths, calligraphy and paintings by Yamaoka Tesshu and Yasuda Yukihiko, and other works that represent the soul of Bushido and the way of life as sublimely as “flowers”.
