Matsuya Route 8 Nagahama Store: 9th 0.000001-Degree Southward Shift Comes About 2 Hours 20 Minutes After the 8th, Cumulative Drift Reaches Nearly 1 Meter

Matsuya Route 8 Nagahama Store (2224) has had its latitude shift south by another 0.000001 degrees on June 25. This is the 9th such shift, coming about 2 hours 20 minutes after the 8th shift, which also occurred on June 25, and the cumulative southward drift since the store’s initial listing in March has reached nearly 1 meter.

The 2nd Shift of the Day, and the Shortest Interval Yet for the 9th

This change reduced the latitude by 0.000001 degrees, from 35.3870865 to 35.3870855. A decrease in latitude corresponds to a southward shift, equivalent to roughly 11cm. The longitude remains unchanged at 136.2842973, meaning all 9 shifts so far have been fine adjustments due south. This is the second time the store has shifted south twice within the same day, following May 1, but the interval from the 8th shift was about 2 hours 20 minutes — shorter than the roughly 6 hours seen that time, making it the shortest interval on record.

Progression Since the First Listing

Since the Route 8 Nagahama store first appeared in the store listing at a latitude of 35.3870945, it has never shifted back north, instead accumulating southward shifts in increments of 0.000001 degrees.

Counting from the initial 35.3870945, the latitude has moved south by a total of 0.000009 degrees, which translates to roughly 100cm on the ground — nearly 1 meter. This milestone comes about 3 months after the store’s initial listing this past March.

A Suburban Store Along National Route 8, Co-located with Matsunoya

The Route 8 Nagahama store is located in Obori-cho, Nagahama City, Shiga Prefecture. As its name suggests, it is a suburban-type store situated along National Route 8, co-located with both Matsuya and Matsunoya (Tonkatsu Matsunoya).

The official photo of the store’s exterior shows a black, box-shaped building with the area around the entrance outlined in a yellow line. On the wall, Matsuya’s red, blue, and yellow logo appears alongside signage reading “Matsuya,” “Matsunoya,” and “Tonkatsu Matsunoya” side by side. This latest fine adjustment to the coordinates does not move the store’s actual location — only the latitude recorded in the store listing has shifted about 11cm south.
