　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”

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)”

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”

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.
