ストスト: The story behind this trend in Social Media today
06-10-2026
The phrase “ストスト” trending on social media today is the fan shorthand for SixTONES STock (ストーンズストック), an experiential warehouse tour by the six-member Japanese idol group SixTONES.The event was created for the group’s sixth debut anniversary and eleventh year since formation. It opens a logistics-style warehouse that stores their creative archivepast live costumes, music-video props and sets, artist photos, original goods, samples of releases, and related materialsso visitors can walk through it for a timed session of roughly 40 minutes. The presentation mixes ordinary viewing with interactive elements such as member commentary triggered by scanning codes, sound and floor effects, and other member-designed touches. It is not a conventional exhibition; the framing is that fans are briefly allowed inside the place where the group’s materials are kept.A Tokyo run was held earlier in 2026 at Ginza Sony Park. The Osaka run is set for ATC Gallery from 21 October to 27 December 2026 (66 days, with two Mondays closed), again on a date-and-time reserved, turnstile basis. Fan-club lottery entry for Osaka ran from 17 to 24 September. Results were scheduled for 6 October, which is why the term spiked: fans posted in large numbers that they had won (“当たった,” often specifying Osaka or a date) or lost (“落選”). Later fan-club first-come and general sales windows follow in mid-October.The same nickname has also been used by the group’s label for streaming-related campaigns, but the posts driving today’s trend are specifically the Osaka lottery outcomes for the warehouse tour.
