Outline

According to the museum, it is thought that the person had been sitting on the stone step waiting for the bank to open when the heat from the bomb burned the surrounding stone white and left their shadow.^[4][3] A black deposit was also found on the shadow.^[4] A piece of stone containing the artifact (3.3 meters wide by 2 meters high) was cut from the original location and moved to the museum.^[5]

In January 1971, the museum acquired the stone, whose human shadow had become indistinct due to weathering. In April 1975, the museum began research into preserving the shadow.^[6] In 1991, the museum reported that earnest investigation of preservation methods had commenced.^[7] At present, the stone is surrounded by glass.^[8][9]

It is thought that the person depicted in the stone died immediately with the flash of the atomic bomb, or after falling down after the explosion.^[4][10] Some people stated that they saw the person sitting at the entrance just before the bombing.^[14] A former soldier testified that he had recovered the person's body. However, the person's identity is still unknown.^[11] As of 2016, the museum exhibit states that "Several people have suggested that the person could be a member of their family". In the past, the museum exhibit contained a statement that the person was a 42-year-old woman named Mitsuno Koshitomo (越智ミツノ).^[11] As a result of these previous statements, some conclusions in the literature state that she was the person depicted in the stone.

According to museum staff, many visitors to the museum believe that the shadow is the outline of a human vaporized immediately after the bombing.^[3] However, the possibility of human vaporization is not supported from a medical perspective. The ground surface temperature is thought to have ranged from 3,000 to 4,000 degrees Celsius just after the bombing. Exposing a body to this level of radiant heat would leave bones and carbonized organs behind. While radiation could severely inflame and ulcerate the skin, complete vaporization of the body is impossible.^[3]

History

Hiroshima Branch of Sumitomo Bank

Human Shadow Etched in Stone was originally part of the stone steps at the entrance of the Hiroshima Branch of Sumitomo Bank, located 260 meters from ground zero.^[2][12] The current location of the Sumitomo Mitsui Banking Corporation, Hiroshima Branch is Kamiya-cho 1 Chome.{{efn|The branch had been in {{ill|Nakajima-cho (Hiroshima)|ja|中島町 (広島市)|lt=Nakajima-Honmachi}} before it was transferred to a new building in {{ill|Kamiya-cho|ja|紙屋町・八丁堀}}.^[13]}}

The bank was built in 1928. It was designed by {{nihongo|Kenzo Takekoshi|竹腰健造}} at the department of engineering of Sumitomo Group (now Nikken Sekkei), and was constructed by the Obayashi Corporation.^[14] The building was constructed out of reinforced concrete, with four floors above ground and one below with an open ceiling up to the third floor. The rooms for business, reception and specie were on the first floor, the meeting rooms and cafeteria on the fourth floor, and the boiler room in the basement.^[14][15] It was built south of the head office of Geibi Bank (Now head office of {{Interlanguage link|Hiroshima Bank|ja|広島銀行|WD=}},) which had been built the year before and was almost the same size. It had Romanesque architecture style in general, and was characterized by a large arch with molding on its front.^[14]

It was not totally destroyed in the bombing of August 6, 1945. While the interior was destroyed, the exterior remained.^[15] The specie room was not damaged, and the cash and passbooks remained.^[15] Papers inside the building were blown as far away as {{Ill|Numata-cho (Hiroshima)|ja|沼田町 (広島市)|WD=|lt=Numata-cho}} by the blast.{{efn|According to the online map,^[16] it is approximately nine kilometers from ground zero to Numata-cho.}}^[15]

The branch reopened after the war, and the entrance soon became a famous landmark of the damage caused by the atomic bombing. It was officially recognized by Hiroshima City as an A-bomb site.^[17] In those days, the shadow was called "Human Shadow of Death".^[2][18] According to a testimony, it was the second most famous sight next to the Atomic Bomb Dome.^[19] Sumitomo Bank went to great lengths to preserve the shadow. In 1959 they built a fence surrounding the stone, and in 1967 they covered the stone with tempered glass to prevent deterioration.^[2][5][18]

In 1971, the Hiroshima Branch was planned to be rebuilt. The stone around the shadow was cut out and donated to the museum.^[2][5]

Saying of human vaporization

According to {{Ill|Masaharu Hoshi|ja|星正治|WD=}}(1947–), a radiology scientist, in his childhood he heard of the saying that the shadow had been generated after human vaporization.^[3] "Journal on the damage of atomic bombing in Hiroshima" (広島原爆戦災誌), published by Hiroshima City in 1971, also contains a description implying human vaporization, which is now proved to be impossible.^[3]{{Quotation|Within a radius of 500 meters of the ground zero, (Omitted) people were killed almost immediately as if they had been vaporized (Omitted) bodies and bones were burned thoroughly almost not to be found, and everything was destroyed, which was buried in white ash.|Hiroshima City|Journal on the damage of atomic bombing in Hiroshima vol.2^[20] (translation mine)}}

In the 1994 Committee on Health and Welfare of the House of Councillors, {{Ill|Eimatsu Takakuwa|ja|高桑栄松}} mentioned the stone, saying "One was vaporized and vanished immediately. Only the shadow remained."^[21]
