Where to verify official Numbers4 results (Japan)
Authoritative winning numbers and rules live on Mizuho Bank and the official takarakuji portal—not on Takarakuji AI. Short checklist for international readers.
Why verify officially?
Takarakuji AI mirrors public draw data for convenience. Only official channels decide whether a ticket wins, how prizes are paid, and the final published numbers for Japan’s authorized lottery products.
Primary official sources
Use pages on official domains only. Avoid copycat or unofficial “mirror” sites if the domain looks wrong.

If a bookmark breaks, open the bank’s or portal’s top page and navigate to “当せん番号” / Numbers4 from there instead of trusting third-party links alone.
How Takarakuji AI fits in
- We do not process claims or payouts.
- There can be a short delay between the official announcement and our database sync.
- If any value disagrees, the official site wins.
Language note
Most official flows are in Japanese. Browser translation helps, but for tickets, taxes, or disputes, rely on official Japanese text or ask an authorized retailer in Japan.
