[Complete Edition] What are Cheap Days on Rakuten Ichiba 2026? Shopping Marathon and 0/5 Days Strategy Taught by New EC Managers

In the EC market of 2026, optimizing the purchasing experience in Rakuten Ichiba is a top priority not only for general consumers but also for new EC managers. Not just the feeling of 'cheap', but understanding point redemption rate (SPU) and event overlap in MECE is the key to minimizing real price. In this article, we thoroughly predict the 2026 Rakuten calendar and explain the most profitable timing from a professional perspective.

1. 3 Elements Defining "Cheap Days" on Rakuten Ichiba in 2026

To judge 'Cheap Day' in Rakuten Ichiba, it is necessary to calculate the following 3 elements compositely, not just superficial discount rates.

• Event Points: 'Shop buying around' points by Shopping Marathon and Rakuten Super SALE.
• Specific Day Points: Regular/irregular campaigns such as 'Days ending with 5 and 0 every month' and 'Double if won'.
• Shop Individual Measures: Store's original coupon issuance and point multiplier (max 19x).

The timing when these overlap is the moment when real price (Selling Price - Expected Acquisition Points) is minimized. This basic structure does not change in 2026, but since optimization of algorithms based on user purchasing behavior progresses, advance research becomes more important.

2. Synergistic Effect of Shopping Marathon and Days with 0/5

What new EC managers should learn first is 'Days ending with 5 and 0' during the 'Shopping Marathon' period. Usually, the Shopping Marathon is held for about a week, but within that period, days ending with '5' or '0' always come around once or twice.

By concentrating payments on this day, points for specific day benefits are granted in addition to maximum 9x (+ normal point 1x) by buying around. As a trend in 2026, maximization of point multipliers by 'Summary Buying' rather than 'Single Item Repeat Buying' has taken root among high loyalty users.

3. Annual Schedule: Catching the Wave of Rakuten Super SALE

The lowest price range in 2026 is 'Rakuten Super SALE' held in March, June, September, and December as usual. During this period, traffic of the entire mall is maximized, and each shop also introduces featured products prepared for deficits (half price or less) for inventory disposal and new acquisition.

Especially in 2026, personalized offers by AI are evolving, and 'cheapest coupons' tend to be distributed at different timings for each user. As an EC manager, it is necessary to analyze which segment your store's coupon resonates with most and watch ROAS (Return On Advertising Spend).
