1. The Significance and Market Scale of Amazon US Expansion

The US market offers Japanese sellers access to enormous consumer spending power, mature e-commerce infrastructure, and strong demand for quality Japanese products across categories.

FBA (Fulfillment by Amazon) handles storage, picking, packing, shipping, and customer service for international orders. For cross-border sellers, FBA eliminates the need for local warehousing and reduces shipping complexity significantly.

2. Building a Supply Chain Using FBA (Fulfillment by Amazon)

FBA handles storage, pick-and-pack, shipping, customer service, and returns—all in English. This eliminates the need for local warehouse infrastructure and English-speaking support staff.

Prime Badge Designation: Stimulates the strong purchasing motivation of US Prime members and dramatically improves CVR (conversion rate).
Improved Buy Box Win Rate: Works advantageously in the algorithm compared to self-fulfillment.
Multi-Channel Fulfillment (MCF): Orders from sales channels outside Amazon can also be shipped from Amazon inventory.

3. MECE Analysis of Logistics Costs in Cross-Border EC

Efficient logistics requires: proper customs documentation, understanding import duties, selecting reliable freight forwarders, and optimizing shipment size for cost efficiency.

First Mile (Japan → US Receiving): International shipping, customs duties, importer fees
Storage & Fulfillment (within FBA): Monthly storage fees, fulfillment fees, labeling options
Reverse Logistics (Returns): Return processing costs, liquidation or disposal fees

To optimize costs, consider Size Tier optimization as a priority. Amazon's FBA fees are calculated based on product dimensions and weight, so even minor packaging adjustments can shift products into a lower Size Tier, significantly reducing per-unit fulfillment costs.
