Claim 1&D

Prove you run 1andd.co.jp and the profile becomes yours to control: a free workspace with 1&D as your company, the public findings brought in as drafts, and a say over every item on the public page. Your claim never opens anyone else's workspace.

Step 1 of 2

Create a free account with your @1andd.co.jp email

We send a 6-digit code to that address. Entering it proves you run 1andd.co.jp.

No address at 1andd.co.jp? Create the account with any email and prove the domain with a DNS record or a tag on your website instead.
