Question: What was added to the Tokyo version of Van Gogh's Sunflowers?
About the article "Sunflowers (Van Gogh series)", section "The "Repetitions", January 1889".

Candidate passages:
The Artistes Indépendants, collaborating closely with Les XX in Brussels, were eager to present Van Gogh to the public in Paris in an even broader scale, and finally showed ten paintings in their 6th annual exhibition, March 20 through April 27, 1890: "832.
Le cyprès."
- The Cypres "833.
Paysage montagneux en Provence."
- Mountain landscape in Provence "834.
Rue à Saint-Rémy."
- Street in Saint-Rémy "835.
Les Alpines."
(!)
- The Alpilles "836.
Promenade à Arles."
- Promenade in Arles "837.
Mûrier en automne."
- Mulberry tree in autumn "838.
Sous-bois."
- Underwoods "839.
Lever de soleil en Provence."
- Sunrise in Provence "840.
Les Tournesols."
- The Sunflowers "841.
Verger d'oliviers en Provence."
- Olive orchard in Provence Evidently, the first part of Van Gogh's exhibit (832.
- 837.)
was now chosen by Theo, while the remainders from Brussels were added (838.
- 841.)
at the end of this selection, excluding one version of the "Sunflowers" (and "The Red Vineyard" sold in Brussels).
Again, Van Gogh exhibit was the "clou" of the show: Gauguin, Guillaumin and other colleagues proposed to exchange works; Duez sent his compliments; and Theo wrote to Vincent that Monet had said, "your pictures were the best of all in the exhibition".
Some of Van Gogh's paintings in the Artistes Indépendants show  
Little is known of Van Gogh's activities during the two years he lived with his brother Theo in Paris, 1886-1888.
The fact that he had painted Sunflowers already is only revealed in spring 1889, when Gauguin claimed one of the Arles versions in exchange for studies he had left behind after leaving Arles for Paris.
Van Gogh was upset and replied that Gauguin had absolutely no right to make this request: "I am definitely keeping my sunflowers in question.
He has two of them already, let that hold him.
And if he is not satisfied with the exchange he has made with me, he can take back his little Martinique canvas, and his self-portrait sent me from Brittany, at the same time giving me back both my portrait and the two sunflower canvases which he has taken to Paris.
So if he ever broaches this subject again, I've told you just how matters stand.
"The two Sunflowers in question show two buttons each; one of them was preceded by a small study, and a fourth large canvas combines both compositions.
These were Van Gogh's first paintings with ""nothing but sunflowers""—yet, he had already included sunflowers in still life and landscape earlier. 
The is the corporate headquarters for Sompo Japan Insurance.
It is located in the district Nishi-Shinjuku in Shinjuku, Tokyo, Japan.
At 200 metres (656 ft), the building is the 28th tallest building in Tokyo and the 33rd tallest in Japan.
It was designed by Yoshikazu Uchida.
On the 42nd floor is Seiji Togo Memorial Sompo Japan Museum of Art, where one of Vincent van Gogh's "Sunflowers" series of paintings is located.
The building is similar in appearance to Chase Tower. 
Two Paris versions Van Gogh exchanged with Gauguin in December 1887 or January 1888 were both sold to Ambroise Vollard: one in January 1895 and the other in April 1896.
The first canvas resided for a short time with Félix Roux, but was reacquired by Vollard and sold to Degas from his estate to Rosenberg, then to Hahnloser and bequested to the Kunstmuseum in Bern.
The second was acquired by the Dutch collector Hoogendijk at the sale of his collection by Kann, who ceded the painting to Richard Bühler and then via Thannhauser to the Metropolitan Museum in New York.
Two of Van Gogh's "Sunflowers" paintings never left the artist's estate: the study for one of the Paris versions (F.377) and the repetition of fourth version (F.458).
Both are in the possession of the Vincent van Gogh Foundation, established 1962 by Vincent Willem van Gogh, the artist's nephew, and on permanent loan to the Van Gogh Museum, Amsterdam.
Five other versions are recorded in the Van Gogh estate papers: the final Paris version (F.452) in the artist's estate was sold 1909 via C. M. van Gogh, The Hague (J. H. de Bois) to Kröller-Müller (F.457) sold 1894 to Emile Schuffenecker.
(Tokyo version).
(F.456) sold 1905 via Paul Cassirer to Hugo von Tschudi.
(Munich version).
(F.459) sold 1908 C. M. van Gogh (J. H. de Bois), The Hague to Fritz Meyer-Fierz, Zürich (destroyed Japan 1945).
(F.454) sold 1924 via Ernest Brown & Phillips (The Leicester Gallery) to the Tate Gallery; since on permanent loan to the National Gallery, London.
(London version).
Two Arles versions left the artist's estate unrecorded: (F.453) (private collection).
Sold 1891 to Octave Mirbeau, Paris, (via Tanguy, Paris) for £12 (about £1,300 in 2013 £).
Sold 1996 to a private collector for an undisclosed sum.
(F.455) (Philadelphia version).  
According to a Christie's sale catalogue, in the early 1890s Antoine de La Rochefoucauld was the owner of Vincent van Gogh's "Still Life: Vase with Fifteen Sunflowers" which Japanese insurance magnate Yasuo Goto paid the equivalent of just under USD $40 million in 1987, at the time a record-setting amount for a van Gogh.
He was also the previous owner of "La Berceuse", a van Gogh now in the Museum of Fine Arts, Boston.
