Decoding Essential Strategies for E-commerce Beyond RPP in 2026

Important Online Seminar on E-commerce Strategies

Scheduled for December 17, 2025, from 15:00 to 16:30 JST, Japan EC Services Co., Ltd. will host an insightful online seminar titled "Decoding Essential Strategies for E-commerce Beyond RPP in 2026." This event aims to empower e-commerce businesses struggling with the recent transition to RPP automatic optimization, a shift that has raised concerns regarding revenue stability and return on ad spend (ROAS).

Seminar Objective

The seminar focuses on providing practical knowledge to help e-commerce vendors reduce unnecessary advertising costs and enhance their sales and profits independently. The session aims to equip attendees with effective differentiation strategies that can mitigate the negative impacts of reliance on advertising while maximizing their growth potential.

Context of the Seminar

Since the transition to RPP automatic optimization introduced in November 2025, many e-commerce operators within the Rakuten marketplace are facing heightened challenges. Reports of accelerated ad consumption and unstable ROAS have surged, reflecting the intense pressure merchants face in adapting their advertising strategies. Furthermore, many businesses are burdened with the responsibility of product registration, shipping, and other operational tasks, limiting their capacity to reevaluate their advertising efforts effectively.

In response to these issues, the seminar will aim to streamline the management processes, making it easier for busy merchants to adopt effective advertising practices that not only minimize waste but also enhance sales performance and ROAS.
