“Are you paying for server fees, domain costs, and phone bills with your personal credit card?”
“You want a business card, but the annual fee worries you?”

If you are just starting out as a freelancer or running a side business, you might be struggling with money management.

Just as you should keep a separate business bank account, separating your credit cards into personal and business use is critically important.

If you are currently paying business expenses with your personal card, you are not only making tax filing harder but also missing out on thousands of dollars worth of points.

In this guide, we explain how to choose the best business credit card based on 2026 trends, including the popular “gold card training” strategy for maximum rewards.

Why You Need a Separate Business Credit Card

You might think, “As long as the bank account is separate, the card can stay personal.” But having a dedicated business card offers two major advantages.

1. Fully Automated Bookkeeping

Connect your business credit card to cloud accounting software (like freee or Money Forward), and all business expenses are automatically recorded in your books.

If personal and business expenses are mixed, you will face the nightmare of manually sorting each transaction. Separating cards eliminates this hassle entirely.

2. Earn Points on Business Expenses

As your business grows, expenses like computer purchases and SaaS subscriptions add up significantly.

By charging all of these to a high-reward card, you can easily earn tens of thousands of points per year. Use those points for new gadgets or office supplies — it is essentially free expense reduction.

The 2026 Trend: Smart Selection and the “1 Million Yen Training”

What kind of card should you choose? Status cards are out; practicality (point rewards vs. annual fee balance) is the 2026 trend.

Target No-Fee or Conditional Fee Cards

While your income is still unstable, there is no need to pay high annual fees for premium cards. Start with no-fee cards or cards where meeting certain conditions waives the annual fee from the next year onward.

The Popular “1 Million Yen Training”

Have you heard of the “1 Million Yen Training” trend on social media?

This is a program offered by certain credit cards (like Mitsui Sumitomo Gold (NL), Aeon Gold, or Epos Gold): spend 1 million yen or more annually, and the annual fee is permanently waived.

Spending 1 million yen on personal expenses alone is tough, but including business expenses — server fees, advertising, inventory, computer purchases — many freelancers cross that threshold fairly easily.

Once you complete the “training,” you enjoy gold card benefits (airport lounge access, higher point rewards) for free forever — an incredibly cost-effective strategy.

Recommended Card Lineups by Purpose

Choose a card based on your lifestyle and the services you frequently use.

1. For the Rakuten Ecosystem: Rakuten Business Card

If you shop on Rakuten and use Rakuten Bank for your business account, the Rakuten business card is ideal. Earn Rakuten points on all business expenses and use them for personal shopping.

2. For Mobile-First Payments: Olive (SMBC)

For those who want to handle everything with smartphone touch payments, flexible pay services like Mitsui Sumitomo Bank’s “Olive” are gaining popularity. With an integrated bank account and credit card, fund transfers and point management are handled in a single app — perfect for tech-savvy freelancers.

A Word of Caution: Don’t Overspend for Points

The most important thing to remember: do not buy things you do not need just to earn points or hit spending targets.

Points are a bonus, not the goal. Increasing unnecessary expenses weakens your business. Stay disciplined and only charge genuinely necessary investments to your card.

Summary: Apply for a Card Alongside Your Bank Account

• Separate cards for accounting automation and points
• If you expect 1 million yen in annual expenses, try the gold card training
• Choose based on your ecosystem (Rakuten, mobile payments, etc.)

January is the perfect time to set up a new year’s bookkeeping. Open a business bank account and apply for a business credit card at the same time. This is the first step to making this year’s tax filing dramatically easier.
