Frequently Asked Questions
Everything you need to know about BBHunt Japan's bug bounty platform
For Companies
A bug bounty program is a
crowdsourced security initiative where organizations invite ethical hackers to
find and report security vulnerabilities in their systems. Researchers who
discover valid bugs receive monetary rewards (bounties) based on the severity
and impact of the vulnerability. This approach provides continuous, real-world
security testing that complements traditional methods like penetration testing.
Penetration testing is a
time-boxed engagement conducted by a small team, usually resulting in a single
report. Bug bounty programs run continuously with hundreds or thousands of
researchers testing simultaneously, providing diverse perspectives and ongoing
coverage. You only pay for valid results, making it more cost-effective for
continuous assurance. Many organizations use both approaches together for
comprehensive security.
Vulnerability report triage is the process of reviewing, validating,
prioritizing, and categorizing submitted vulnerability reports. It helps
organizations quickly identify real security risks, remove duplicates or
invalid submissions, and ensure critical issues are addressed efficiently.
Bounty amounts are set by
each organization based on their budget and the severity of vulnerabilities.
BBHunt Japan provides recommended reward ranges based on industry benchmarks and
CVSS severity ratings. Typical ranges start from ¥10,000 for low-severity issues
and can exceed ¥1,000,000 for critical vulnerabilities. We help you design a
reward structure that attracts top talent while staying within budget.
Yes. BBHunt Japan is fully
compliant with Japan's Act on the Protection of Personal Information (APPI). All
platform data is hosted on servers located in Japan. We operate under strict

For Researchers
Signing up is free and
takes only a few minutes. Visit our signup page, provide your basic information,
and verify your identity. Once approved, you'll gain access to available public
programs and can apply for private programs. We accept researchers from anywhere
in the world — you do not need to be based in Japan to participate.
Bounty payments are
processed after a vulnerability has been validated and accepted by the company.
Payments can be made via PayPal and other methods. Payment processing typically
takes 5-10 business days after approval.
Responsible disclosure
means reporting vulnerabilities privately to the affected organization through
our platform, giving them time to fix the issue before any public disclosure.
All researchers on BBHunt Japan must follow our responsible disclosure policy.
This protects both the company and the researcher, ensuring legal safety and
ethical conduct throughout the process.
We use the Common
Vulnerability Scoring System (CVSS v3.1) as the standard framework for rating
severity. Vulnerabilities are classified as Critical, High, Medium, or Low based
on factors including exploitability, impact on
confidentiality/integrity/availability, and the specific context of the affected
system. Each program may also define its own priority levels and reward tiers.
Absolutely. BBHunt Japan
welcomes researchers from all over the world. Our platform interface is fully
bilingual (English and Japanese), and our AI-powered translation system ensures
smooth communication between researchers and companies regardless of language.
Some private programs may have geographic restrictions, but most public programs
are open to global participants.
