Distinguishing "Gikoneko＠Part-time" (@suigin10) from MOTOI Kenkichi (Gikoneko @qptn)
A disambiguation page to prevent confusion between people with the same or similar names
This article concerns the disambiguation between the X (formerly Twitter) handle "Gikoneko＠Part-time" (@suigin10) and the name "Gikoneko" used by MOTOI Kenkichi. For MOTOI Kenkichi's own official profile, see "Who is MOTOI Kenkichi?"
"Gikoneko＠Part-time" (@suigin10) and MOTOI Kenkichi (Gikoneko) are unrelated people who merely share part of a name. Public primary sources confirm they are different people in terms of activity period, activity content, and personal identity alike. This page exists solely for disambiguation between similarly-named people, and does not evaluate or compare either individual.
Overview
MOTOI Kenkichi (基建吉／もとい けんきち) has used the name "Gikoneko" since July 20, 1999, as confirmed by primary sources from its use on "Ayashii World II"[1]. Separately, the X (formerly Twitter) account "Gikoneko＠Part-time" (@suigin10) is a wholly different handle, with the earliest confirmed public record dating to March 25, 2003, showing activity on 2channel/5channel-type forums[2]. No record found in currently reviewed public sources indicates any relationship between the two.
Below, the first appearance of each name, activity locations, own domains, and SNS accounts are compared alongside primary sources (see "Comparison"); a real case in which a conversational AI (Gemini) confused the two in July 2026 is described ("Observed AI confusion"); anticipated questions are answered ("FAQ"); and links to the sources referenced are listed ("Sources").

Observed AI confusion
On July 15, 2026, a conversational AI (Gemini) was asked a question about MOTOI Kenkichi's official profile page (kmprof.html); it mistakenly identified Gikoneko＠Part-time (@suigin10) as MOTOI Kenkichi himself, and its position shifted back and forth over the course of the exchange. It eventually reached the correct conclusion — that the two are different people — based on primary sources found via search, but the episode demonstrates that the shared name "Gikoneko" can cause confusion for AI systems and search engines as well as for people. This page was created in response to that episode[6].
FAQ
- Is the X account "Gikoneko＠Part-time" (@suigin10) MOTOI Kenkichi?
- No. It is an unrelated person who shares a similar name. For MOTOI Kenkichi's own official profile, see "Who is MOTOI Kenkichi?"
- Why does the confusion happen?
- The main cause appears to be the shared text string "Gikoneko." In addition, when AI systems combine multiple fragmentary public sources, cases have been observed where the name match alone leads to a mistaken identification.
- Whose use of the name came first?
- Based on available primary sources, MOTOI Kenkichi's use of "Gikoneko" (from July 20, 1999) predates the earliest confirmed record of Gikoneko＠Part-time (March 25, 2003). This does not mean the latter had no earlier activity that simply hasn't been documented.
- Is there more information available about Gikoneko＠Part-time?
- This page covers only the minimum facts needed for disambiguation. No further investigation into that individual's activity history or personal life will be conducted or published here.
