Early access for people in Japan using multiple credit cards
MyCards.jp
The live spending meter for your Japanese credit cards.
See this month's spending before the bill arrives. MyCards turns card notification emails into one simple total for today, this month, and each card.
Multiple cards, one total
Bring Rakuten, SMBC, Amex, JCB, and other card alerts into one simple view.
No finance suite required
Skip the budgeting maze when you just need the current card total.
Positioning
A spending meter, not another finance app.
You should not have to wait for a statement to find out you overspent. MyCards is built for people in Japan who use multiple cards and want one current answer.
The question
How much have my cards spent this month?
The moment
Check the live total before another purchase.
The view
Today, this month, and each card in one place.
The boundary
Current card awareness without accounting-suite clutter.
How it works
From card alert to live total in minutes.
Connect Gmail, detect supported card notification senders, and turn recent alerts into a current monthly total.
01
Connect Gmail
Start with card notification emails, not bank logins.
02
Detect card alerts
Identify supported card senders and focus the scan there.
03
Update totals
Use the amount, date, card, and merchant when available.
04
Check before spending
Open one simple total before deciding whether to spend more.
Trust model
Gmail access should be clear before you connect.
MyCards is built around card notification emails, so the product explains what is used, what is shown, and how you stay in control.
No bank login required
MyCards starts from card notification emails in Gmail instead of asking for card-site credentials.
Sender-focused scanning
Supported card notification senders are the focus, not a broad personal finance feed.
Reviewable fields
See the amount, date, card, merchant when available, and review status so totals are easier to audit.
Connection explained first
Understand the Gmail connection and early product boundaries before you choose to connect.
Early access
See where the month is heading before the bill arrives.
Join early access if you use multiple cards in Japan and want one calm monthly total before statements catch up.
Before the statement
Know sooner
Turn card alerts into a current view of today and this month.
Multiple cards
One place for alerts
Bring supported card notifications together without opening every card app.
Timely reminders

Get practical reminders when spending starts moving faster than expected.
Built for multi-card life in Japan
For people who use several Japanese cards and lose track before month end.
Especially useful for Rakuten, SMBC, Amex, JCB, and other card users who want fewer surprises when the statement arrives.
