Matsuya's 0.000001-Degree Southward Latitude Shift Series Hits 8th Round as 4 Stores Return at Once

On the Matsuya official website’s store list, it was confirmed that as of 10:28 AM on June 19, 2026, the latitude of 4 stores was simultaneously revised 0.000001 degrees (about 11cm) southward. This marks the “8th round” of the southward latitude shift series that has continued since April 25, with Matsuya No. 8 Nagahama store (2224, Shiga Prefecture) and Matsuya Sendai Ichibancho store (2260, Miyagi Prefecture) — dormant for about 43 days since the 4th round on May 7 — returning to the series. Matsuya Miyakojima Tomobuchi-cho store (2214, Osaka Prefecture), a series regular, reached a cumulative shift of -0.000008 degrees (about 88cm) southward, while Matsuya Shin-Yurigaoka store (2321, Kanagawa Prefecture), which joined for the first time yesterday on June 18, also saw its latitude revised southward for a second consecutive day.

The 8-Round Southward Shift Series Since April 25

The series began on April 25 with 4 stores moving simultaneously, but from May onward it continued as a solo run by the Miyakojima Tomobuchi-cho store alone. In today’s 8th round on June 19, the dormant No. 8 Nagahama and Sendai Ichibancho stores returned for the first time in about 43 days, and with Shin-Yurigaoka — which had just joined yesterday on June 18 — participating for a second consecutive day, this became the series’ largest-scale simultaneous southward shift, involving 4 stores at once.

No. 8 Nagahama and Sendai Ichibancho Stores Return for the First Time in 43 Days Since May 7

The No. 8 Nagahama store (Shiga Prefecture) and the Sendai Ichibancho store (Miyagi Prefecture) had participated in the series through the 4th round on May 7, but from May 26 onward they dropped out, leaving a phase in which only the Miyakojima Tomobuchi-cho store continued its southward shift alone. In today’s 8th round on June 19, both stores returned to the series simultaneously after about 43 days of dormancy. The cumulative southward shift reached about 44cm (5th round) for the No. 8 Nagahama store and about 33cm (3rd round) for the Sendai Ichibancho store.

Shin-Yurigaoka Store: Latitude Revised for a Second Consecutive Day Following Its June 18 Debut

The Shin-Yurigaoka store (Kanagawa Prefecture, scheduled to newly open on June 26, 2026) had its latitude revised 0.000001 degrees southward in yesterday’s June 18 store data update, marking its first participation in the series. In today’s update at 10:28 AM on June 19, it was revised 0.000001 degrees southward again, making it the store’s second southward shift in an interval of less than a single day. This is a rare instance of consecutive adjustments for a store that has not yet opened, with a cumulative southward move of -0.000002 degrees (about 22cm) now reflected.

The Series’ Largest Scale Yet: A Phase Shift to 4 Simultaneous Southward Moves

Today’s 8th round on June 19 is the first time since the series’ opening day (April 25, with 4 stores simultaneously) that 4 stores have shifted southward at once. The composition echoes the series’ early “4 stores at once” phase, with other stores suddenly rejoining the long solo phase carried by the Miyakojima Tomobuchi-cho store alone. Compared to the previous solo-phase rounds (May 26, June 15, June 17), the scale per round has quadrupled — a move that can be read as suggesting a “phase shift” in the series.
