Hi @hiroki-hasegawa,
I have manually removed the connection between your Bitbucket account and CircleCI identity.
Could you try logging in again and re-linking them? In general:
- Clear browser cache
- Log in to Github account
- Log in to Bitbucket account
- Authenticate CircleCI via Github account
- Link Bitbucket account on user settings page
If the issue is persisting, I think it would be better to handle this via a support ticket:

Please let us know if you have any additional questions as well.
