イオイカ (Eoeca)

イオイカ, branded on the page as ランダムチャット イオイカ ("random chat Eoeca"), is a Japanese text chat site organised around user-created rooms. There is no account to register: a small form on the right of the desktop page asks for a nickname, gender, age (a number from 10 to 99) and region, followed by a button to set the nickname.

The main column is a room list showing each room's region, title, occupancy, owner, owner's gender and age. A 'create room' button sits above it, and the left sidebar filters rooms by age group (teens to 50s) and by Japanese region, from Hokkaido to Kyushu and Okinawa. At the time of the visit the list held a single open room with one of ten places taken, and its owner's age was listed as 1, which suggests the age field is not checked. Activity looked very slow.

A notice under the room list states that rooms with inappropriate titles are automatically shut down by the system, and the footer links to a youth protection policy and customer support. No moderators or report buttons were visible on the landing page. The footer names the operator as ライベストソフト with a business registration number and a Gmail contact address.

On desktop, ads occupy both side columns; during the test they were image ads for a French home security firm, which is out of place on a Japanese site but not intrusive. On mobile the layout adapts reasonably, with filters and room creation in the header, but a consent dialog appears first. It mentions sharing data with 210 partners and offers 'Consent' and 'Manage options', the latter being where you can refuse. The site loaded over HTTPS without warnings or redirects.

イオイカ suits Japanese speakers who want a quick, signup-free room chat and like the idea of filtering by age and region. With only one room open during the visit, expect to wait or to start your own room and hope others drop in.
