Photograph of Iwasaki Yataro, photographer unknown, before 1885; National Diet Library, Japan, Portraits of Modern Japanese Historical Figures · Portrait photograph of Iwasaki Yataro (photographer unknown), taken during his lifetime and therefore before 1885, shown as portrait 3 on the National Diet Library (Japan) 'Portraits of Modern Japanese Historical Figures' page for him (image file 0237_3.jpg, 1529 x 2064 pixels) and drawn from the 1967 'Iwasaki Yataro-den' vol. 2 in the NDL Digital Collections (info:ndljp/pid/2976210). Rights basis: (1) the library's 'About This Site' page, which I read live, states that all images used in this digital exhibition are in the public domain and may be reproduced or reused, including for commercial use, without application to the library, with the source cited; (2) independent of that, the photograph was necessarily taken before the sitter's death in 1885, so its copyright in Japan (photographs under the 1899 Act, anonymous author) expired long before 1996 and was not restored in the United States, and for the United States an unpublished or published anonymous photograph of that age is in the public domain; (3) the 1967 book is only a photographic reproduction of a two-dimensional photograph. Caveats: the photographer and the exact date are not stated on the NDL page (a Commons note elsewhere says the portrait was taken in 1874 citing a Japan Art Archive entry that I could not open, so I record only 'before 1885'); I could not read the NDL's per-image source caption because it is not exposed in the page; the portrait is recorded as a likeness because it is a lifetime photograph of him. Lead check: the lead's initial lead was this same NDL portrait (the 630 x 582 Kokushi Shozo Taisei plate on Commons); I used the larger NDL file of the same sitter instead. File downscaled from 1529 x 2064 to 889 x 1200 pixels, never upscaled. · Public domain (National Diet Library statement that exhibition images are public domain; lifetime photograph taken before 1885)

Trait Constellation
Key Achievements
He turned the Tosa clan's shipping business into the private steamship company he named Mitsubishi in 1873, which became Japan's dominant shipping line and the origin of the Mitsubishi zaibatsu, the second largest family-owned industrial-financial combine of his era.
He opened the Yokohama-Shanghai line in 1875, won a price war with the American firm Pacific Mail, and moved into coal (Takashima, 1881) and shipbuilding (the Nagasaki shipyard, leased 1884), the roots of Mitsubishi's mining and heavy-industry businesses.
His company's rise relied on government favour and drew press attacks and complaints of monopoly pricing; after a costly rivalry with Kyodo Unyu, a merger created NYK in 1885, the year he died.
Moments That Reveal Them
In 1874, when the government struggled to find a carrier to move troops and supplies to Taiwan, Mitsubishi accepted the job despite the risks, and afterwards received government-supplied ships that greatly enlarged its fleet.
This is consistent with a willingness to take on risky commitments, though the account is largely the company's own and state backing lowered the risk. Risk Tolerance
In the Shanghai fare war with Pacific Mail, fares fell by more than half; Mitsubishi cut executives' pay, won the contest and bought out the American line.
This is consistent with a strongly competitive approach to rivals, though the details come mainly from the company's own history. Competitiveness
Turning Points
When the clan domains were abolished around 1870-73, he took over the Tosa clan's shipping business as a private concern and, from 1873, ran it as Mitsubishi.
This is consistent with seizing an opening created by institutional change, though sources differ on the exact dates and the terms of the takeover. Opportunity Sensing
