Matsuya Oyama Kizawa Location: Latitude Shifts South by 0.000001 Degrees Again on Opening Day, 7th Time Overall

Matsuya Oyama Kizawa (store No. 2313) opened as scheduled at 10 a.m. on July 31. At almost the same moment the store opened, the latitude of its registered coordinates on Matsuya’s official website shifted another 0.000001 degrees south, marking the 7th downward latitude revision since the location was added to Matsuya’s store list on July 9. Even on its very first day in business, the brand-new store’s coordinates were still being fine-tuned.

Latitude Shifts South by About 11 Centimeters

This time only the latitude changed; the longitude did not move.

Item	Before	After
Latitude	36.344034	36.344033
Longitude	No change	No change

A shift of 0.000001 degrees in latitude works out to roughly 11 centimeters, and every shift so far has been southward, this time by about 11 centimeters due south. Counting from the latitude of 36.344041 recorded when the store was added to Matsuya’s store list on July 9, the coordinates have moved south by 0.000008 degrees over 22 days, a cumulative shift of about 89 centimeters. Each individual adjustment is smaller than the width of a finger, but the direction has never once reversed to north: July 9, 14, 16, 23, and now opening day on the 31st have all moved consistently southward.

Opening Notice Removed, Opening Confirmed

Alongside the southward shift in coordinates, the listing for this store on Matsuya’s official website also changed. The “*Opens July 31 at 10 a.m.” notice that had been attached to the store name, along with the scheduled opening date and time entry, were both removed, confirming that the store opened as planned at 10 a.m. on July 31. The notice disappearing at precisely the opening time itself served as confirmation that the opening had gone ahead.

Second Location in Oyama City; Tochigi’s Matsunoya Co-location Rate at 90%

Oyama Kizawa is located in Oyama City, Tochigi Prefecture, and is co-located with Matsunoya. This brings the number of Matsuya locations in the city to two, alongside “Matsuya Oyama.”

Tochigi Prefecture now has 11 Matsuya locations in total, 10 of which are co-located with Matsunoya. The only standalone Matsuya without a Matsunoya co-location is the Utsunomiya Orion-dori location, putting the prefecture’s Matsunoya co-location rate at about 91%. Nationwide, 472 of Matsuya’s 1,209 locations are co-located with Matsunoya, a rate of about 39%, meaning Tochigi’s co-location rate far exceeds the national average and points to a strong prefectural lean toward Matsunoya co-located openings.

Minor Latitude Adjustments Seen Across Matsuya Locations Nationwide

These 0.000001-degree southward latitude adjustments are not unique to Oyama Kizawa. In just the recent period, the same magnitude of coordinate revision has repeatedly appeared at locations across the country, including Sendai Ichibancho, Route 8 Nagahama, and Miyakojima Tomobuchi-cho, suggesting this is a pattern occurring across Matsuya locations as a whole. From stores about to open to stores that have just opened, the steady fine-tuning of location data has become a familiar fixture of Matsuya’s store information.
