Print taped to it as what it calls a "financial eye-catcher" The oldest known channel for chain letters is written, or printed, on letters on paper. These might be exchanged hand-to-hand or distributed through the mail.
Early examples and precursors In Europe, letters known as "
Himmelsbrief" (; ) existed, with examples dating back as early as the 6th century. One notorious early example of a money-based chain letter was the "Prosperity Club" or "Send-a-Dime" letter. This letter started in
Denver, Colorado in 1935, based on an earlier luck letter. It instructed recipients to send a dime to the person at the top of a list of names, remove that name, add their own to the bottom, and mail the letter to five others, warning of misfortune for breaking the chain. They may also be politically motivated, such as "Save the Scouts, forward this to as many friends as possible" or a warning that a popular TV or radio show may be forced off the air. Some, such as the
Hawaiian Good Luck Totem, which has spread in thousands of forms, threaten users with bad luck if not forwarded. One chain letter distributed on MSN
Hotmail began, "Hey it's Tara and John the directors of MSN..." and subsequently claimed readers' accounts would be deleted if they did not pass on the message. Another common form of email chain letter is the
virus hoax and a form of
cyberbullying.
Email chain letters in Japan With the rise of email and mobile phones, digital versions of Fukou no Tegami, known as "Fukou no Mail" (不幸のメール - Unlucky Mail), emerged. supposedly about a girl from
Indiana who was pushed down a sewage drain in a fire drill, states that, "if you do not repost/send this to 10 people, Carmen will find you and kill you." Chain letters are often coupled with intimidating
hoaxes or the promise of providing the sender with "secret" information once they have forwarded the message.
SNS and forum chain messages in Japan From around 2011, email chain letters declined in Japan, while similar messages spread via
SNS. On
Twitter (now X), this often takes the form of pressured
retweets (now reposts), while on
LINE, messages urge forwarding to a specific number of contacts. Common LINE examples since 2016 include: "Copy this and send to 10 people or misfortune will befall you," or "You received this because you're important to me. Send this to 20 people you truly like. If you don't, friends or lovers will leave you." The latter type, leveraging friendship anxiety, reportedly caused real friction when recipients felt pressured to forward, annoying their contacts. Some include phone numbers to call "if you think it's fake," but these are often unrelated third-party numbers used for harassment, or sometimes linked to organized crime. Surveys indicate high exposure among Japanese teenagers, with many admitting to forwarding them. Online forums like
Yahoo! Chiebukuro and Nifty Kids receive numerous相談 (sōdan - consultation) requests about these messages. On Japanese
imageboards and forums like
2channel (now
5channel), copy-paste chain messages also appear. One notable type emerged around 2002, involving narratives where the poster claims to be possessed or hunted by a malevolent entity (e.g., "Are" - "That Thing") and urges readers to spread the story to dilute the entity's focus, ending with statements like "If you want to increase your own survival probability, I recommend exposing this text to as many eyes as possible." These are sometimes called "self-responsibility type" (自己責任系,
jiko sekinin kei) stories. Since around 2007, an image known as the "Hand of God" (神の手,
Kami no Te)—depicting a hand-shaped cloud with sunbeams—has circulated frequently on Twitter and LINE in Japan. Typically accompanied by text claiming that sending it to people you wish happiness upon will bring them good luck and grant wishes, the image has been flagged by security firms like
G DATA Software as potentially linked to
malware. (Meteorologists state such cloud formations are impossible; the image likely originated as a doctored version of a
shock image from
Goatse.cx.) The image gained renewed attention in 2021 when celebrities posted it on
Instagram, prompting warnings. This "Hand of God" image represents a shift back towards positive "good luck" chains, albeit with potential security risks. On
TikTok, sounds tagged "#いいことが起きる" (#GoodThingsWillHappen) gained popularity around 2022-2023, particularly among Japanese high school students, promising fulfilled wishes if used in posts. These represent a further evolution towards positive, low-stakes chain-like phenomena, contrasting with the anxiety-inducing nature of Fukou no Tegami. While digital copying allows perfect replication, potentially halting the mutation seen in handwritten letters like the "Stick Letter," new forms and variations continue to emerge across different platforms, suggesting the underlying mechanisms of chain letters constantly adapt to new media. ==Reasons for popularity==
