Preface: “Why do so many Japanese people make the two-finger ‘peace sign’ in photographs?” is one of the perennial What’s Up With Japan questions. Sadly, the answer given usually derives from a half-assed Google search in which most of the pages found are just quoting Wikipedia anyway.

This article attempts to summarize what is reliably known about the matter at the present time, with links to related information online where possible. Readers are invited to add any evidence of their own, including verifiable sources, in the comment thread.

Part A: V for “Victory”

A1. V-sign for “Victory” (Europe): Promoted by various Allied groups during WWII to symbolize local cognates of “victory.” Gestural V-sign made famous worldwide when adopted by Winston Churchill.

A2. V-sign for “Victory” (Japan, post-war): Churchill-style V-sign hypothesized to have been introduced into Japan by Allied occupation. Evidence scarce.

A3a. V-sign for “Victory” (Japan, pre-Bubble): Enters popular consciousness in late 1960s via baseball manga/anime Kyojin no Hoshi 『巨人の星』 (“Star of the Giants”). Hero Hyūma believes father has not come to say goodbye at train station as he departs for Kōshien, but father appears at last moment and throws up V. Hyūma recognizes it as “the V-sign of victory!” (“Shōri no V-sain!“) and resolves to win.

A3b. V-sign for “Victory” (Japan, pre-Bubble): In 1969, creators of girl’s volleyball manga Sain wa V 『サインはV』 (“V is the sign”) are inspired by A3a to drench product in V-sign — like early hip-hop producers taking only best part of drum break and repeating over and over. Sain wa V adapted into live-action drama and, like Kyojin no Hoshi, became leading hit in ongoing “sports grit” (スポーツ根性, スポ根) boom. Meaning of V-sign is spelled out in opening lines of theme song: “V, I, C, T, O, R, Y/ Sain wa V!”

A3b-supplement. Comment from Jimbo Shirō 神保史郎, writer of original Sain wa V manga:

I respected [Kyojin no Hoshi writer] Kajiwara Ikki. He was the sort of writer I wanted to become. The scene in Kyojin no Hoshi when Hoshi Hyūma is about to set off for Kōshien, and then his father appears and thrusts out that V-sign made a big impression. In a meeting with the editors, I suggested that we call our new story V Mexico, since the Mexico Olympics were coming up and all. After a lot of debate, we decided that Sain wa V was more straightforward and worked better.

Part B: V for “Peace”

B1. V-sign for “Peace” (USA): Exact origins unclear, but seems to date from 1960s’ U.S. counterculture, and in particular, anti-Vietnam War (= pro-peace) sentiment. Gradual dilution to symbolize solidarity in struggle against The Man as well as simple “peace.”

B2a. V-sign for “Peace” (Japan): As elements of counterculture spread to Japan, so does V-sign. Adopted by student radicals of late 1960s as well as relatively apolitical followers of foreign fashions. (Possible inspiration for A3a?)

B2b-supplement. Many sources cite Japanese popularity of Janet Lynn, U.S. figure skater and heartwarming dojikko, during and after the 1972 Sapporo Olympics as likely inspiration, claiming that she was often shown in the Japanese media flashing the peace sign. No evidence located.

Part C: V for “Cheese”

C1. V-sign in photographs: “Victory” (?) (Japan): Current oldest known example in poster for 1960 film Oku-man choja 『億万長者』 (“The Millionaire”) clearly shows Nakahara Hitomi 中原ひとみ making V-sign and smiling at camera. (Discovery credit: Kepel-sensei.)

C2. V-sign in photographs: “Peace” (Japan): In 2007 episode of Downtown DX, Inoue Jun 井上順 claims to have popularized V-sign in photographs via 1972 Konika commercial, in which he ad-libbed use of the V-sign by photographed persons, inspired by anti-war movement.

C3. V-sign in photographs: “Cheese” (Japan): All sources agree that by 1980s, use of V-sign in photographs was unremarkable and spreading slowly up the age scale.

Part D: Conclusions and unresolved questions

D1. Timeline synthesized from information above:

• V-sign becomes powerful, positive gesture during WWII
• Use of V-sign as part of photography pose dates back to at least 1960
• Revitalization of V-sign as counterculture “peace” sign in ’60s/’70s coincides with period in which Japanese youth was both interested in U.S. youth culture and had means to import its artifacts and habits
• However, early connection to “victory” was not forgotten: use of V-sign to mean “victory” had extremely high visibility in youth-targeted media around 1970
• Thus, at this time, “victory” and “peace” meanings may have reinforced each other, raising profile of gesture still higher. (E.g. Inose suggests that Kajiwara was inspired to write Kyojin no Hoshi V-scene by strong media presence of V-flashing anti-war demonstrators.)
• Meanwhile, rising incomes and many Japan-based camera makers meant more photos by non-professionals → space for photography folkways to develop (encouraged by camera companies, e.g. Inoue Jun’s CM story)
• Post-1980, gesture has lost emotional resonance and becomes part of “camera pose,” eventually to develop into modern variations that flatter face shape, emphasize eyes, highlight nail art, etc.

D2. Further questions:

• Could long /i/ sound in “peace” have made it particularly attractive to photographers looking for a hipper version of “cheese”?
• To what extent can the in-photo popularity of the “peace” sign, whatever its origins, be attributed to its nature as a widely recognized performance, protecting the subject from visual capture at an awkward or vulnerable moment? (cf pouty MySpace poses, throwing the horns, etc.)
• No relation to U.S. bunny-ears photo prank? (Would one not expect such horseplay to be much more common than bombastic Churchillian V’s among occupying GIs?)
• Did GHQ in fact use mind control or genetic engineering to impose “peace” sign on Japanese nation, as reportedly hypothesized by Igeta Seiichi (aged 17)?
