Good morning. This is まさきん.
While browsing a list of campaigns that give away points, I spotted a stamp rally announcement. It is called the IRIS PLAZA Stamp Rally Campaign. It says “up to 10x points,” so I sorted out the conditions.
What kind of campaign is this
I wrote in an earlier article that campaigns come in types. I think this one is the limited-time point-back type, where the multiplier rises with the number of items you buy.
It applies to the official Iris Ohyama store on Rakuten Ichiba. Entry is required, and the period runs from Tuesday, September 1 at 10:00 to Saturday, October 31 at 9:59.
Stamps, multipliers, and the cap
The way it works is simple. First, you enter. Then you get one stamp each time you buy one item priced at 1,000 yen or more (tax included). You can collect up to 5 stamps, and each person can take part only once.
The point multiplier goes up with your stamp count, as follows.
- 1 stamp: 3x (regular 1x + 2x bonus)
- 2 stamps: 6x (regular 1x + 5x bonus)
- 3 stamps: 7x (regular 1x + 6x bonus)
- 4 stamps: 9x (regular 1x + 8x bonus)
- 5 stamps: 10x (regular 1x + 9x bonus)
The multiplier does not rise evenly. Going from 1 stamp to 2, it jumps from 3x to 6x. On the other hand, going from 2 stamps to 3 only adds one step, from 6x to 7x.
“Up to 10x” sounds big. However, the bonus points have a cap. You can earn up to 1,000 points (limited-time points).
With 5 stamps, the bonus is 9x, which means 9%. By a simple calculation, you hit the cap once purchases earning that 9% reach about 11,100 yen before tax. The points are scheduled to be granted around Thursday, December 31. They expire on Wednesday, June 30, 2027 at 23:59.
If you want to earn more points, reviewing your phone bill might be another option. Rakuten Mobile can also be applied for through my referral. If you switch while keeping your number, you can get up to 14,000 points. If you haven’t yet, please take a look.

What was a little hard to understand
If you only look at “up to 10x points,” you might think everything you buy earns 10x. In reality, it is the multiplier you get once you have collected 5 stamps.
There is another point: the amount is viewed in two ways. A stamp is counted for an item priced at 1,000 yen or more including tax and before coupons. The bonus points, on the other hand, are based on the amount excluding tax and after coupons. So even for the same item, the standard is a little different.
I could not tell from the page exactly which order gets which multiplier. If you are curious, it might be safer to check the official explanation as well.
The same page also runs a newsletter campaign in which 100,000 points are shared among the first 100,000 people. By calculation, if 100,000 people join, that comes to 1 point each.
What to check before you apply
- Entry is required. The deadline is Saturday, October 31 at 9:59, and purchases made before you enter also count.
- Eligible items are those priced at 1,000 yen or more (tax included) per item at the official Iris Ohyama store on Rakuten Ichiba.
- Multi-piece sets, such as a 2-piece set, count as 1 stamp per set.
- Pre-orders are not eligible. Subscription purchases and periodic-delivery club purchases (hanpukai) are eligible.
The page says that if you cancel a purchased item, you are excluded from the campaign. It also says that buying from a different page may not give you a stamp.
A cap on the multiplier is very similar to what I wrote in the shop-hopping article. Working backward from the cap to decide how much to buy seems to apply here too.
Summary
The IRIS PLAZA stamp rally was a campaign where the multiplier rises on items priced at 1,000 yen or more. With 5 stamps it reaches up to 10x, and the cap on bonus points is 1,000 points.
I think the best approach is not to buy extra things just for the points. It might suit people who already buy things like water and daily goods in bulk. Conditions and periods may change, so please check the official site for the latest information.
While we are on the subject of points, how about also reviewing your family’s phone lines? Rakuten Mobile gives up to 14,000 points through my referral. That applies when you switch while keeping your number.
