Waitrose cut launch time 25%: Building a Japanese range for modern demand

Waitrose wanted to grow its chilled meals category and attract younger shoppers with something culturally relevant, not another generic “Asian-inspired” range. The team needed to understand where Japanese food demand was actually moving and whether it had the momentum to support a full product launch.

Using Tastewise, the innovation team analyzed real consumer demand signals across recipes, menus, and social conversations. These signals showed that Japanese cuisine was gaining traction beyond niche restaurant trends and resonating with younger shoppers looking for bolder, more authentic meal options.

That evidence gave the team the confidence to move quickly. Instead of testing isolated dishes, Waitrose built a full Japanese-inspired range designed around what consumers were already craving.

Waitrose needed a clear, data-backed reason to invest in a new cuisine direction and bring it to market quickly.

• Trend signals were fragmented
  Signals around Japanese cuisine were scattered across social media, menus, and food conversations, making them difficult to interpret.
• Innovation needed to attract younger shoppers
  The team wanted to refresh the chilled meals category and bring in customers who were looking for more adventurous global flavors.
• The cuisine bet needed proof
  Before committing to a full range launch, teams needed confidence that Japanese demand would scale beyond a short-lived trend.

Tastewise helped the team turn early trend signals into a clear product strategy.

• Identifying real demand signals
  Tastewise analyzed recipes, menus, and social food conversations to show how Japanese dishes and ingredients were gaining traction.
• Pinpointing the drivers behind the trend
  The platform revealed the specific cues driving demand, from flavor combinations to dish formats that resonated with younger shoppers.
• Translating signals into a range roadmap
  Instead of launching isolated products, Waitrose used the insights to design a cohesive Japanese-inspired range aligned with real consumer interest.
• Building internal confidence
  The data-backed narrative helped innovation and category teams align around the opportunity and move forward faster.

With Tastewise, Waitrose turned early trend signals into a real product range that delivered measurable commercial impact across both speed and shopper engagement.

• 25% shorter launch time
  The Japanese-inspired range moved from concept to shelf in just nine months, significantly faster than the usual product development timeline. Early validation from Tastewise signals helped teams move forward with confidence instead of spending weeks gathering additional research.
• £5 higher spend per basket
  The range resonated particularly well with younger shoppers looking for bolder global flavors. Customers who purchased from the new line tended to add more items to their baskets, increasing average spend per shop.
• 3% market share lift
  After the range launched, Waitrose saw measurable growth in the Asian meals category. The new products helped strengthen the retailer’s position in a fast-growing segment while bringing new shoppers into the category.
