.otsuka entered the DNS root zone on August 27, 2014, 12 years ago. It came out of ICANN's New gTLD Program, the 2012 application round that grew the root from 22 generic TLDs to well over a thousand.
On the technical side, .otsuka is served by 4 authoritative name servers, 3 of them reachable over IPv6. It is also DNSSEC-signed: the root zone carries a DS record for .otsuka, which lets validating resolvers check its answers cryptographically.
