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

Candidate passages:
On March 31, 1987, even those without interest in art were made aware of van Gogh's "Sunflowers" series when Japanese insurance magnate Yasuo Goto paid the equivalent of US $39,921,750 for Van Gogh's "Still Life: Vase with Fifteen Sunflowers" at auction at Christie's London, at the time a record-setting amount for a work of art.
The price was over four times the previous record of about $12 million paid for Andrea Mantegna's Adoration of the Magi in 1985.
The record was broken a few months later with the purchase of another Van Gogh, "Irises", by Alan Bond for $53.9 million at Sotheby's, New York on November 11, 1987.
While it is uncertain whether Yasuo Goto bought the painting himself or on behalf of his company, the Yasuda Fire and Marine Insurance Company of Japan, the painting currently resides at Seiji Togo Yasuda Memorial Museum of Modern Art in Tokyo.
After the purchase, a controversy arose whether this is a genuine van Gogh or an Emile Schuffenecker forgery. 
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  
In November 1889, Van Gogh selected six of his paintings, all size 30 canvases, to be displayed at Les XX, in 1890.
On the back of the letter of invitation from Octave Maus, dated November 15, 1889, there is a pencil sketch that gives some hints for the display Van Gogh proposed, and for its artistic background.
His reply to Maus, dated (?)
November 20, 1889, supplied the titles later printed in the catalogue, but did not point out the arrangement he intended:  "1.
Tournesols" - Sunflowers  "2.
Tournesols" - Sunflowers  "3.
Le lierre" - Ivy  "4.
Verger en fleurs (Arles)" - Flowering Orchard (Arles)  "5.
Champ de blé; soleil levant (Saint-Remy)" - Wheat Field, Sunrise (Saint-Rémy)  "6.
La Vigne rouge (Mont-Major)" (!)
- Red Vineyard (Mont-) Fortunately, the missing information can easily be compiled from other parts of Van Gogh's correspondence; there is now agreement that Van Gogh's exhibit can be reconstructed in the order of paintings below:"Ivy", the center piece of Van Gogh's arrangement, has been lost without trace since World War II; Hermann Göring is the last person photographed (by Hans Hoffmann) with this canvas, while it was stored, together with other works of art confiscated from French Jewish collections, in the Jeu de Paume Galleries.
Van Gogh indicated his two "Sunflowers" (size 30 canvases) were to be displayed either side of "Ivy".
To the left and right of this upright triptych, he wanted to place the "Flowering Orchard" and the "Wheat Field at Sunrise".
Finally, he indicated "Red Vineyard" was to be hung (at the top or) underneath this arrangement. 
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).  
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.
