Conclusion

To conclude, the following are recommended in order from top to bottom.

In our home, we used “Hada e no Ichiban (the slightly better one)” until our child was 1.5 years old.

[Choose 1 type] Pampers Diapers Hada e no Ichiban Tape (3 packs) [Pampers Hada e no Ichiban] [Hada e no Ichiban] Buy on Rakuten

For Hada e no Ichiban, regardless of size, I believe it's considered cheap if the price per diaper is 26-27 yen or less.

And after 1.5 years old, we started using “Sarasara Care (the basic one)”.

[Choose 1 type] Pampers Diapers Sarasara Care Pants (1 set) [Pampers] [Sarasara Care] Price: 8,980 yen~ (tax included, shipping extra) (as of 2026/6/11) Buy on Rakuten

For Sarasara Care, it's slightly cheaper, and regardless of size, I believe it's considered cheap if the price per diaper is 24-25 yen or less.

(There isn't much difference, but it might be because of a size-up... or rising prices.)

So, I hope you can use these price ranges as a reference.

Bulk Buying on Rakuten Ichiba

First and foremost, I recommend Rakuten Ichiba.

More specifically, the Rakuten24 Baby Store is cheap.

Rakuten Ichiba has a system called "SPU", where the point return rate increases as you use various Rakuten services.

In our home, we use Rakuten Card and Rakuten Mobile, so our SPU is quite high, but even if you don't, I believe you can buy them cheaper than at physical stores by aiming for shopping marathon campaigns and coupons.

Hada e no Ichiban

First, let's look at "Hada e no Ichiban".

Tape Type

[Choose 1 type] Pampers Diapers Hada e no Ichiban Tape (3 packs) [Pampers Hada e no Ichiban] [Hada e no Ichiban] Buy on Rakuten

Pants Type

Pampers Hada e no Ichiban Diapers Pants (4 packs) [Pampers] Price: 8,959 yen (tax included, shipping extra) (as of 2026/6/11) Buy on Rakuten

This is a screenshot from the Rakuten Super Sale on June 5th.

A 4-pack set of M-touch (224 diapers) costs 8,959 yen, with an
800 yen OFF coupon, and an additional 2,471 points are redeemed.

This calculates to approximately 25.393 yen per diaper, which is a fairly low price.

Sarasara Care

Next, let's look at "Sarasara Care".

Tape Type

[Choose 1 type] Pampers Diapers Sarasara Care Tape (4 packs) [Pampers] [Sarasara Care] Price: 9,156 yen (tax included, shipping extra) (as of 2026/6/11) Buy on Rakuten

Pants Type

[Choose 1 type] Pampers Diapers Sarasara Care Pants (1 set) [Pampers] [Sarasara Care] Price: 8,980 yen~ (tax included, shipping extra) (as of 2026/6/11) Buy on Rakuten

This is also a screenshot from the Rakuten Super Sale on June 5th.

A 4-pack set of M-touch (248 diapers) costs 8,980 yen, with an
800 yen OFF coupon, and an additional 2,474 points are redeemed.

This calculates to approximately 23.008 yen per diaper, which is also a fairly low price.

In the case of Rakuten24 Baby Store, in addition to the regular SPU, there's often a 20% point back, which directly leads to lower prices. (Try to buy when this 20% point back is available.)

Therefore, bulk buying on Rakuten Ichiba is the simplest and most effective method, so be sure to check it out.

Rakuten Pay Irregular Campaigns

Rakuten again. (We're grateful for their service.)

This is limited to those who use Rakuten Pay, but

Rakuten Pay occasionally holds campaigns like this.

In this campaign, if you pay for eligible products with Rakuten Pay,
you get 30% back for Hada e no Ichiban
and 20% back for Sarasara Care.

During the campaign, you'll see such pop-ups displayed in the Pampers sections of Nishimatsuya and drugstores, which is your sign.

This is also recommended because it's easy to just buy at the store, offers the lowest prices, and the redeemed Rakuten points can be spent as Rakuten Pay.

OK Store × Mitsubishi UFJ Card

This is limited to those who have a Mitsubishi UFJ Card, but

With a Mitsubishi UFJ Card, you can receive point redemption at the following eligible stores.

If you buy diapers at the discount supermarket "OK Store" among these, you can buy them cheaply.

Recently, "Akachan Honpo" was also added! That's great.

(As of June 2026)

Although it largely states "up to 20% redemption", it's basically 7%, and it increases as you use various UFJ services, and in my case, it's 12.5%.

So, if I talk about it with a 12.5% redemption rate,

With a Mitsubishi UFJ Card, "Global Points" are redeemed and can be exchanged for Amazon gift cards and other items, but their redemption rate is low.
Instead, by using them as an exchange option called "Global Points Wallet", you can achieve the highest redemption rate.

This is explained in detail below.

It's a bit complex, but once set up, it becomes advantageous for purchases other than diapers, so I think it's a good card to have.

(There's a friend referral campaign for Mitsubishi UFJ Card. If you're interested, please comment with your email address, and I'll send it as soon as possible. We both benefit.)

Bulk Buying on Yahoo! Shopping

Yahoo! Shopping can also offer a reasonably high redemption rate if you aim for specific days.

Amazon

Finally, Amazon.

The advantage of Amazon is that you can order from 1 pack, but since there are no special point redemptions, it's about the same price level as buying at a physical store.

Even if you buy 4 packs in bulk, it's 32 yen per diaper.

I'm an Amazon Prime member, use Subscribe & Save, and utilize Amazon extensively, but for diapers, it's not remarkably cheap. Of course, there are cheaper days.

Taking advantage of being able to order from 1 pack, here's how to utilize Amazon:

Pampers diapers have QR codes attached to their bags,

When scanned with the Pampers app, you accumulate points that can be exchanged for Amazon 500 yen OFF coupons and other rewards.

Since it's a 500 yen OFF coupon, applying it to a single pack order rather than a bulk purchase can lower the unit price per diaper, so I always exchange it for Amazon coupons.
