Project overview
Rainbowgirl is a randoseru (Japanese school backpack) brand that KETCHUPs built from zero as its own new business — not client work. We developed the brand identity and product line, built the direct-to-consumer store on Shopify, and grew the audience through social media marketing.
After establishing the brand and its sales channels, the business was transferred to Kitsutsuki Kobo, a specialist school-bag maker, which continues to operate the brand today.
Highlights
- Brand built from zero — launched and operated as KETCHUPs’ own venture
- Direct-to-consumer store designed and built on Shopify
- Customer acquisition driven by social media marketing
- Successful handover — business transferred to Kitsutsuki Kobo, where the brand lives on
Notes
Rainbowgirl is the project where KETCHUPs ran every stage in-house — brand, store, marketing, and operations — the same end-to-end scope we now apply to client launches in Japan. The brand is currently sold by Kitsutsuki Kobo.
