Matsuya Sendai Ichibancho's Latitude Drifts South for the 15th Straight Time, Cumulative Shift Reaches About 1.7 Meters

Store data on Matsuya’s official website shows that the latitude of Matsuya Sendai Ichibancho (store code 2260) shifted 0.000001 degrees south, from 38.2621291 to 38.2621281, as of August 2, 2026. The longitude remained unchanged at 140.8711560, meaning the coordinates moved only along the north-south axis — a shift equivalent to roughly 11 centimeters south on the ground.

Longitude Unchanged, Only Latitude Creeping South Since Late April

The store’s latitude on the official site has shifted south in consistent 0.000001-degree increments ever since it first moved from 38.2621431 to 38.2621421 on April 25, 2026. With the August 2 update, that southward drift has now reached 15 consecutive occurrences. The total drop from the original 38.2621431 to the current 38.2621281 comes to 0.0000150 degrees — converting at roughly 111.32 kilometers per degree of latitude, that works out to about 1.7 meters south.

The standout feature of this store’s coordinate changes is that, over roughly 99 days, the longitude has never once moved while the latitude keeps ticking south by the same fixed increment. The step-by-step progression is as follows.

Date	Latitude	Cumulative shift from before the first change
Apr 25, 2026 (1st)	38.2621421	approx. 11 cm
Jun 24, 2026 (5th)	38.2621381	approx. 55 cm
Jul 22, 2026 (11th)	38.2621321	approx. 122 cm
Jul 28, 2026 (13th)	38.2621301	approx. 145 cm
Aug 2, 2026 (15th)	38.2621281	approx. 167 cm

The most recent time this store’s coordinates were covered on their own was July 28, 2026, when the cumulative shift stood at about 1.4 meters. On July 14, 2026, the store’s latitude on the official site was even seen moving south three separate times within the same day, each by 0.000001 degrees. By June 24, 2026, the fifth southward step had pushed the cumulative total to about 55 centimeters, with the shift steadily accumulating since. Several other Matsuya locations show the same pattern of latitude alone inching south little by little, and they share the trait of having been added to the official site’s store list relatively recently.

Matsuya Locations Cluster Around Ichibancho, Three Within Walking Distance

The area around 3-10-17 Ichibancho, Aoba-ku, Sendai, where Matsuya Sendai Ichibancho stands, is also a Matsuya-dense neighborhood. The closest location by straight-line distance is Matsuya Sendai Minamimachidori, about 472 meters away, followed by Matsuya Sendai Jozenjidori at about 491 meters and Matsuya Sendai Chuo at about 761 meters — all clustered within a 500-to-800-meter radius of central Aoba-ku.

Sendai City is home to 12 Matsuya locations in total, meaning three-quarters of the 16 Matsuya stores currently operating in Miyagi Prefecture are concentrated in the city. This latest shift of a mere 11 centimeters south is simply the newest step in the quiet coordinate drift continuing within that Ichibancho cluster.
