The Big Adventure of Owata's Life (人生ｵﾜﾀの大冒険, Jinsei Owata no Daibouken)¹⁾ was a series of AA threads around 2006²⁾ that focused on Owata's attempts at heading into Jukai,³⁾ but he dies and explodes in a Mega Man-like fashion,⁴⁾ which stops further progress.

However, this name has mostly been associated with the Flash game that was developed by “King” (キング ◆KING75wl/Q) during the late 2000s, famously serving as the main inspiration for popular trial-and-error games like I Wanna Be The Guy and Shobon Action.

The game is very simple to understand. In the final version, there are four routes (detailed below), each of which depend on the direction that Owata goes in, and a total of five to six bosses.

Around late 2006, “King” was a college student who liked AA threads on 2channel and Flash games, so he decided to develop a Flash game on an AA thread during Winter Break.⁵⁾ The initial version released on January 1, 2007⁶⁾ with the starting screen and Kuma fight,⁷⁾⁸⁾ then he started to add more to the game⁹⁾ with tanasinn as the first boss¹⁰⁾¹¹⁾ and it kept spreading around the internet.

This early version famously inspired “Kayin”, who went on to develop and release I Wanna Be The Guy on October 7, 2007.¹²⁾ In turn, “King” was motivated by I Wanna Be The Guy's explosive popularity to finish developing Jinsei Owata no Daibouken. As such, the full version released on September 20, 2009,¹³⁾ notably adding a direct tribute to I Wanna Be The Guy, and the two congratulated one another.¹⁴⁾

The page for Jinsei Owata no Daibouken used to have a changelog, but the link to it was removed and it stopped updating after the v1.07 update on February 25, 2011. Despite the fact that the game is roughly over a decade old, Jinsei Owata no Daibouken has quietly received updates since 2019 after news about the end of Flash gained traction, then Ruffle compatibility was added.

Jinsei Owata no Daibouken 2 (人生オワタの大冒険2), sometimes shortened to Owata 2, is a sequel that was developed by “King” and published on August 15, 2020^15)16)17)18) with “Asagen” handling music.¹⁹⁾²⁰⁾ Considering the circumstances, the game was a love letter to the AA and Flash era, as the end of Flash was looming, resulting in a much easier game that allowed players to beat it in the final five months.

Unlike the original game, Jinsei Owata no Daibouken 2 has a story where Owata faces an existential threat, with the AA world disintegrating as Flash's scheduled end comes on December 30, 2020. The game has a total of 15 maps and 2 bosses that the player can resume from at any time. Owata faces Yaruo and Yaranaio, then has an Undertale-style²¹⁾ battle with Mona and many other AA characters.

• Shobon Action - Inspired.

• Before the addition of Tanasinn, the map before the room that eventually led to Tanasinn initially had an “Under Construction” (工事中, Kōji-chū) sign placed over the door.²²⁾
• In the past, Easy Mode was originally called “Yutori Mode” (ゆとりモード, lit. “Relaxed Mode”), but the modes were later renamed to Easy and Hard so the reference wouldn't be lost to time.²³⁾
• Owata has four poses: the “Owata” pose (O), the “What The Hell” pose (N),²⁴⁾ the “Fuji-san” pose (F), and a cool dabbing pose with a clinking “shakīn” (シャキーン) noise (S).
• In the credits, the game is actually romanized as “Zinsei Owata no Daibouken” instead.
