Momotaro / Forever Challenge

Read the campaign story

Suntory announced Pepsi NEX Zero’s Momotaro Episode ZERO in February 2014, with national broadcast beginning on 8 March. Shun Oguri played the folklore hero in a dramatic live-action adaptation under Forever Challenge. This case covers the Momotaro entertainment series as one family. It does not retell the separate comparative-tasting execution announced alongside it or duplicate the library’s broader Pepsi Challenge case.

Editorial interpretation: a familiar story supplies a recognisable world while cinematic reinterpretation changes the audience’s expectations of scale and tone. The challenger theme connects the hero’s task with a brand attitude rather than demonstrating a beverage property. Serial storytelling can reward return attention, but it also creates a practical burden: each short instalment must make sense to viewers who missed earlier chapters and still identify the sponsoring brand.

The official source supports the launch, premise and performer, not a sales effect or a measured change in brand preference. The study does not adopt taste-test claims from the adjacent execution. Folklore familiarity is not universal, and any adaptation must examine cultural context and rights in specific translations or modern versions. The proposed test uses an original, nonviolent fictional task, with no imitation of dangerous action, costumes, music or protected production design.

Use familiarity as an entrance rather than a substitute for clarity

A known story can reduce the time needed to establish a world, but audiences differ in what they recognise. Identify the minimum context necessary for a newcomer to follow the action and provide it within the piece. Avoid relying on a famous name alone to explain motives or stakes. When adapting cultural material, ask informed reviewers whether changes preserve an understandable relationship to the source without flattening it into generic spectacle. A useful campaign invites recognition and discovery together. It should offer something to people who know the story well and remain legible to those encountering it for the first time.

Give the brand a role beyond the final frame

Entertainment may attract attention while leaving the sponsor disconnected from what viewers remember. Establish the brand’s thematic role early in the creative brief, then check whether that role is visible without requiring an explanation after viewing. An attitude such as persistence can connect a story to a brand, but it is not proof of product performance. Keep those levels separate. A small organisation might sponsor a series about learning a craft and provide practical materials alongside it. The useful connection comes from a consistent contribution to the experience, not from placing a logo on otherwise interchangeable dramatic content.

Design instalments for both return viewers and first arrivals

A serial needs continuity, yet advertising distribution rarely guarantees that people see episodes in order. Give every instalment a small complete action while leaving a larger question open. Use consistent cues to orient viewers and provide an optional route to earlier chapters. Do not withhold essential product information behind multiple videos. Before production, test the sequence in order and in shuffled order with different groups. If newcomers cannot understand the central proposition, simplify the recap rather than adding more exposition to every scene. The goal is a cumulative experience that rewards attention without punishing ordinary fragmented viewing.

A bounded test for another brief

Proposed adaptation: an adult creative-writing club could develop three original storyboard episodes about a fictional team assembling a community exhibition. The club supplies a clearly identified practical contribution in each episode. Compare sequential viewing with a single randomly selected episode, using the same total discussion time. Ask participants to describe the immediate task, the continuing question and the club’s role. Use no borrowed folklore characters, public submissions or hazardous action. Keep the work private and obtain permission for any contributor text. This tests serial coherence and sponsor attribution without claiming that cinematic scale or a famous performer is necessary for attention.

Measure standalone understanding, desire for another chapter and correct sponsor-role recall. Distinguish narrative curiosity from product preference. Note confusion caused by missing episodes rather than treating it as desirable mystery.

Stop if the story requires unsafe imitation, misrepresents cultural material, obscures essential information or leaves the sponsor attached only through an unexplained logo.
