Inside a Japanese Spice Brand's Shopify Bundle Strategy

Toranoi Spice sells spice kits, not cakes or skincare, and that made choosing the right bundle setup harder than it looks. A single flavor category leaves little obvious room for bundling until you look at how the brand actually built it. Shopify spice bundles work best when the bundle mechanic matches how customers already want to shop, and Toranoi is a clean example of that in practice.

Swell's 2026 bundling report found that brands implementing product bundles see sales increase by 20% and profit gains of up to 30%, based on McKinsey data. That kind of lift rarely comes from a random discount. It comes from bundles designed around a specific catalog and a specific kind of buyer.

Toranoi is a spice kit brand from Sapporo, Japan, built on the back of a curry restaurant that ran for 24 years. When the building closed, the founder turned the same recipes into spice kits people could recreate at home. Let us walk through how they set up Shopify spice bundles using PushBundle's Mix and Match and Volume Bundle features.

The Story Behind Toranoi Spice

Sapporo is known for intense competition among curry restaurants. Toranoi's founder ran a curry shop there under the name Curry Pao for 24 years, building a loyal local following. When the building it operated from was scheduled for demolition, the restaurant had to close.

Rather than let those recipes disappear, the founder turned them into spice kits customers could use at home. The brand kept the same flavor profiles that made the restaurant popular, just packaged for a kitchen instead of a dining room.

That backstory matters here. Toranoi's products are not generic spice blends. Each kit represents a specific dish that used to be served in person, which shapes how customers think about buying more than one.

What They Sell

Toranoi's core lineup is built around a small set of curry and noodle spice kits, each tied to a dish from the original restaurant.

Soup Curry Kit – A spice kit for the chicken-based soup curry the restaurant was known for, serving 3 people across 2 batches.

Roux Curry Kit – A thick curry roux spice kit meant to transform a home cook's usual curry, serving 5 people across 2 batches.

Ethnic Tomato Ramen Kit – A tomato and miso-based ramen spice kit serving 4 bowls.

Dry Keema Curry Kit – A water-free keema curry spice kit built around turmeric, serving 3 people across 2 batches.

Alongside the kits, Toranoi sells standalone blends like their house spice mix, chili spice, and garam masala, plus a chai mix. Every product ties back to a specific recipe rather than a generic seasoning.

What Makes Toranoi Stand Out

Most spice brands sell convenience. Toranoi sells a specific memory. Every kit exists because a real dish, at a real restaurant, built a following over two decades.

That history gives the brand something a newer store cannot fake. Customers who ate at the original restaurant already know exactly what a kit should taste like before they even open the bag.

The brand's blog reinforces this constantly, sharing recipe variations and behind-the-scenes stories from the founder. It reads less like a store and more like a chef still cooking for the same regulars, just through a different channel now.

Challenges They Faced on Shopify

A small, flavor-based catalog creates a specific kind of bundling problem. Toranoi needed customers to try more than one kit, but a single fixed bundle would not fit how people actually wanted to buy.

Challenge 1: Customers Could Not Choose Which Kits to Combine

A fixed multi-pack forces every buyer into the same combination of flavors. Someone who only wanted Roux Curry and Ramen Kit still had to take whatever else was in the box.

For a brand with just four core spice kits, that restriction was especially limiting. Regulars from the original restaurant often had strong flavor preferences and did not want to pay for kits they would not use.

Challenge 2: A Single Kit Purchase Had No Reason to Grow

Shopify's default product page shows one quantity field per product. A customer buying Roux Curry saw no incentive to buy two or three instead of just one.

For repeat customers who already knew they loved a specific flavor, there was nothing on the page encouraging them to stock up. Every extra unit required a separate, deliberate decision with no pricing reward attached.

Challenge 3: Building Either Bundle Type from Scratch Would Take Development Work

Shopify does not natively support a customer-built assortment, where shoppers choose which products and how many go into a set. It also has no built-in tiered quantity pricing tied to bundle logic.

Building either feature with custom code would have meant ongoing developer time, especially to keep pricing accurate as products or prices changed. That was not realistic for a small, founder-run brand.

How PushBundle Solved It

Toranoi implemented two separate PushBundle features, each solving a different part of the problem. Mix and Match handled variety, and Volume Bundle handled loyalty to a single flavor.

Solution 1: A Mix and Match Bundle Customers Build Themselves

PushBundle is Shopify's Mix and Match bundle app that lets Toranoi offer a "choose any 3 spice kits" set instead of one fixed combination. Customers pick exactly which kits they want, and the storefront tracks their progress as they go.

The product page shows a live selection count, currently at 2 of 3, so shoppers always know how many more items they need to complete the set. The final price recalculates automatically based on which specific kits were chosen.

The bundle also includes a flat 300 yen discount and free shipping once completed, both applied without any manual pricing work. Customers get the flavors they actually want, and Toranoi gets a larger order than a single kit purchase would have produced.

Solution 2: A Volume Bundle That Rewards Buying More of One Flavor

For customers who already know their favorite kit, Toranoi set up a separate Volume Bundle on individual products like Roux Curry. The product page shows a simple quantity selector with built-in tiered pricing.

Buying two kits unlocks a 5 percent discount. Three kits unlocks 7 percent off, and five or more unlocks a flat 10 percent discount. Each tier is shown clearly on the page, with the original price struck through next to the discounted total.

This gives loyal, single-flavor customers a direct reason to buy in bulk instead of ordering one kit at a time. It works alongside the Mix and Match bundle rather than competing with it, since each solves a different buying pattern.

Solution 3: Both Bundles Run Natively on a Fully Japanese Storefront

PushBundle's bundle logic does not depend on the storefront's language. Every discount tier, progress indicator, and price calculation on Toranoi's site works exactly the same in Japanese as it would in English.

That matters more than it might seem. Many bundle solutions assume an English-language store during setup, which can create translation or formatting issues later. Toranoi's storefront shows no sign of that friction anywhere in either bundle.

Conclusion

Toranoi Spice did not need a huge catalog to make Shopify spice bundles work. It needed two bundle types that matched two real buying patterns already present in its customer base. Mix and Match gave new and curious customers a way to sample multiple flavors in one order. Volume Bundle gave loyal, single-flavor customers a reason to stock up instead of reordering constantly. Toranoi's setup is a useful reference for any small, flavor-focused food brand weighing whether bundling makes sense with a limited product range. It does, once the bundle type actually matches the customer.

If your Shopify store sells a small but loyal catalog like spices, sauces, or specialty foods, a combination of Mix and Match and Volume Bundle features might solve more than one problem at once. PushBundle is free to install on the Shopify App Store.
