What is IDARE? Why Should You Care?
IDARE is a “prepaid card that earns money”—your card balance receives a 2% annual return, which is 100 times higher than typical Japanese bank savings account rates (around 0.02%). The operating company, Fivot Inc., was established in 2019, has raised ¥3 billion in funding, and won 1st place in the Financial Innovation category at the Tokyo Financial Awards 2024.
Account opening is completely free, and virtual cards are issued instantly. After completing identity verification (eKYC), all features are unlocked: balance limit increases from ¥100,000 to ¥1,000,000, single transaction limit reaches ¥500,000, and you can apply for a physical card for in-store purchases.
Core Benefits at a Glance

| Foreign Transaction Fee | 0% (typical credit cards charge 1.6%-3%) |
| Annual Fee | Free |

IDARE can be used at various merchants in Japan including restaurants, supermarkets, convenience stores, department stores, and transportation
International Use: True 0% Fee Experience
IDARE’s advantage for international purchases is remarkable. Foreign transaction fees are completely waived, with only the Visa official exchange rate applied (typically about 1% above mid-market rate), making the total cost far lower than traditional credit cards’ 3-4%.
Real-World Data Comparison
Actual Case: A user made a $196.71 purchase in the US, and IDARE charged approximately ¥29,400. Using a typical credit card with 2% foreign transaction fee would have cost ¥30,004—saving about ¥600 in a single transaction.
In a Taiwan exchange rate test, IDARE’s rate was ¥4.68/TWD, better than local currency exchange at ¥4.87 and typical credit cards at ¥4.78.
For the same $2,000 purchase, IDARE’s 0% fee saves ¥6,000-12,000 in extra costs

Auto-Deposit Feature and PayPay Step Strategy
How Auto-Deposit Works
IDARE’s auto-deposit function supports daily, weekly, or monthly frequencies, automatically charging from your linked credit card or bank account. Setup: Home screen “Savings Box” → “+Add” → Select frequency and amount.
This means: to maximize returns, deposit amount must be 5x your expected return. Example: To earn ¥1,000/month with ¥600k balance, you need to deposit at least ¥5,000.
Optimal Balance Allocation
| Monthly Avg Balance | Monthly Return | Required Deposit | Annual Yield |
|---|---|---|---|
| ¥300,000 | ¥500 | ¥2,500 | ¥6,000 |
| ¥600,000 | ¥1,000 | ¥5,000 | ¥12,000 |
| ¥960,000 | ¥1,600 | ¥8,000 | ¥19,200 |
| ¥1,000,000 (max) | ¥1,667 | ¥8,335 | ¥20,000 |
PayPay Step Achievement Strategy
Many users choose IDARE because it can be combined with PayPay Step to significantly boost credit card rewards. To understand this strategy, we need to clarify PayPay Step’s rules first.
PayPay Step is a tiered reward system. To reach the highest level, you must meet two conditions within one month:
First condition: Transaction count—You need to complete at least 30 transactions using PayPay Card (credit card), with each transaction being ¥200 or more. While this sounds simple, deliberately accumulating 30 transactions can be tedious for those with limited daily spending scenarios.
Second condition: Total spending—These 30 transactions must total over ¥100,000. This means an average of ¥3,333 per transaction, or you need several large purchases to raise the total.
When both conditions are met, PayPay Card’s base reward rate increases from 1.0% to 1.5%, earning you an extra ¥500 per ¥100,000 spent.
What Role Does IDARE Play?
IDARE’s auto-deposit feature plays a crucial role here, easily helping you achieve the seemingly tedious “30 transactions” requirement. Imagine: You simply set IDARE to auto-deposit ¥500 or ¥600 daily, and the system automatically charges your linked PayPay Card once per day. Over 30 days, this naturally generates 30 transaction records, each meeting the ¥200+ requirement.
Regarding the deposit amount choice, there are two specific considerations. First, ¥500 is the minimum auto-deposit amount IDARE allows. If you want to complete the transaction count task with minimal capital, ¥500 is your starting point.
However, you may notice I also mentioned the ¥600 option. This involves a detail in PayPay Card’s point system: PayPay Card’s basic rule is 1 point per ¥200 spent. When you deposit ¥500 daily, calculating by this ratio, you should earn 2.5 points, but since the point system doesn’t give you 0.5 points, you actually only get 2 points, meaning only ¥400 worth of spending counts toward point accumulation. In other words, that ¥100 of spending value “evaporates.” However, if you choose ¥600 daily deposits, that’s exactly 3 points, and the full ¥600 spending value converts to point rewards without waste. While it’s only a ¥100 difference per day, it accumulates to ¥3,000 over a month—worth considering for efficiency-maximizing players.
Even better, this process is completely automated. You don’t need to deliberately go to convenience stores to rack up transactions, split online purchases into multiple orders, or track “how many times I used my card today” in Excel. IDARE’s auto-deposit acts like a quiet assistant, silently completing this task in the background.

But There’s Another Key Issue to Solve
Attentive readers may have noticed: If you only use IDARE for ¥600 daily deposits, you’ll only have ¥18,000 in a month, still far from the ¥100,000 spending requirement. This is why IDARE can only serve as a “transaction count filler” and cannot complete the entire PayPay Step challenge alone.
To reach ¥100,000 in spending, you need to use PayPay Card for daily large expenses. For example, grocery shopping, online electronics purchases, hotel and flight bookings, utility bill payments, etc. Ideally, you should concentrate all credit card-payable expenses onto PayPay Card, letting IDARE handle transaction counts while daily large purchases handle the total amount.
🎯 Complete PayPay Step Achievement Path
Set IDARE to auto-deposit ¥500-600 daily, steadily contributing 30 transaction records. Then consciously direct large expenses to PayPay Card in daily life. Specific example: If you plan to buy ¥50,000 worth of appliances this month, plus daily supermarket shopping, food delivery, online snacks totaling ¥30,000, adding IDARE’s ¥18,000, you can simultaneously meet both “30+ times” and “¥100,000+” conditions, successfully unlocking the 1.5% high reward rate.
