Looking back at the intervals, the gap from the 1st to 2nd shift was 12 days, and from the 2nd to 3rd was as long as 43 days. By contrast, the 3rd to 4th shift came just 3 days apart, and this latest 4th to 5th shift came after only about 2 days — a sign that the southward moves have been happening in quick succession lately. This marks the shortest interval yet for the store’s southward shifts. The longitude has never moved, and all five shifts have consistently been due south.

Other Stores Showing the Same Pattern

This pattern of latitude shifting south by 0.0000010 degrees at a time is not unique to Sendai Ichibancho. Since it began simultaneously at multiple stores on April 25, stores across the country — including Miyakojima Tomobuchi-cho in Osaka, No. 8 Nagahama in Shiga, and Shin-Yurigaoka in Kanagawa — have continued to see similar step-by-step southward shifts in latitude alone. Most recently, on June 23, Shin-Yurigaoka reached a cumulative total of about 44cm south, and the pattern has developed into Shin-Yurigaoka and Sendai Ichibancho alternately racking up southward shifts.

Sendai Ichibancho is a Matsuya Shokudo location co-located with a Matsunoya, and signage in front indicates it supports takeout bento pickup. The building itself continues to stand in the same spot in Ichibancho, Aoba-ku, Sendai — only the coordinates on the map are moving. Though the difference remains less than a meter, with each revision the store’s position on the map creeps steadily further south.
