1. Multi-Store Expansion: Definition and Strategic Significance

The "EC Multi-Store Expansion Strategy" is a management approach that parallelly operates multiple sales channels—such as an in-house EC site, Amazon, Rakuten, and Yahoo! Shopping—to maximize customer touchpoints and disperse risk. By avoiding the "platform risk" of depending on a single platform and approaching different user segments, it aims to improve LTV (Customer Lifetime Value).
