A case study of our own digital product line: "Japan Insider", a series of English travel guides for first-time visitors to Japan, sold on Gumroad (kensei26.gumroad.com). This is our own business's work — researched, written, designed and published by us. It is not client work, and no client results are claimed.
What was made
11 single guides at US$10 each: Japan Without the Awkward Moments / Get the Tax Back / Step Into Edo / Ride Japan Like a Local / Solo Female Travel in Japan / Kyoto Without the Crowds / Eat Japan Like a Local / Luggage-Free Japan / Sengoku Stories / Tattoo-Friendly Onsen in Japan / New Year in Japan — The Survival Guide
2 bundles: First Trip Japan Essentials (US$19) and Japan Insider Complete Bundle (US$49)
One further title (Japow — a ski guide) is produced and scheduled for the winter season
How each guide is produced
Topic selection from questions first-time visitors actually ask
Research in Japanese primary and official sources, with a fact-check memo kept for every product
English copy written for one specific reader, in plain language
Full product production: buyer PDF, series cover under one design system (navy panel + bold white type), store listing copy and search tags, and matching social posts — with the live listing checked on the page after publishing
What this demonstrates
Japanese-source research, English copywriting, digital product production and series design — the same skills behind our market-entry deck service, applied to our own store.
Deliverable formats in this project
Case study deck (3 slides) as PDF + editable PowerPoint.
