If you want to reduce your travel costs even a little, the conclusion is simple.

👉 Just by using Rakuten Mobile, the effective price of your Rakuten Travel booking can change by ¥10,000–¥20,000

Even with the same hotel and the same plan, the reason for the difference is:

👉 The “stacking” of point multipliers and campaigns

---

■ If You Are Only a Rakuten Member

• Point return: around 1–3%
• Coupons: general distribution only

👉 Savings are limited to a few thousand yen

---

■ If You Use Rakuten Mobile

The following benefits are added:

• Higher point multiplier through SPU
• Mobile user–exclusive campaigns
• Special coupons and point rewards

👉 You can get both discounts and points at the same time

---

■ How Much Difference Does It Make?

👉 If you travel at least once a year, you can almost certainly get your money’s worth

For example, for a ¥100,000 trip:

• Discount: ¥5,000–¥10,000
• Point return: ¥8,000–¥12,000

👉 A total difference of around ¥10,000–¥20,000 is realistic
