Who runs it

Run by LY Corporation. The research records the operator as: LY Corporation (formerly LINE Corporation)

Where does LINE Search get its results?

In-app search inside the LINE app, so no web home URL is recorded. From late June 2023 all web search in LINE Search was switched to Yahoo!検索 and the web search functions outside the switch ended; in-app content such as stickers, themes, official accounts, OpenChat, friends and talks stays searchable inside LINE[4]. A LINE user guide updated 2026-09-03 says the results come from Yahoo!検索[5]. Yahoo!検索 in turn runs on Google search technology[1], so the chain is LINE Search to Yahoo!検索 to Google. LINE and Yahoo Japan became LY Corporation on 2023-10-01[1]. LINE's page for its own crawler, Linespider, is undated and still published: it says the crawler gathers web data for search results in LINE services and follows the Robots Exclusion Protocol[2, 3].

What could not be verified?

These claims about LINE Search came up in the research, but no page that could be read confirms them. They are kept apart, and nothing above rests on them.

  • Linespider still crawls, and what it feeds now that LINE Search web results come from Yahoo!検索.

    Why it is open: No dated primary statement on the crawler's current role was found.

    How it was checked

    Sources 2 and 3 (undated crawler page, still published on 2026-11-10); sources 4 and 5 do not mention the crawler.

  • The about.yahoo.co.jp copy of the 2023-06-14 release on the LINE Search switch.

    Why it is open: The host does not resolve. The same release was read in full from the lycorp.co.jp archive[4], so the fact is verified and only this URL failed.

    How it was checked

    Source 6 https://about.yahoo.co.jp/pr/release/2023/06/14a/ : getaddrinfo ENOTFOUND.
