In the Chowhound forum was a thread on the Japanese grocery store opening in West Houston last year (Houston Business Journal and Houstonia wrote about it last March). The grocery store is Seiwa Market.
Houston Press wrote about it last week briefly in the opening and closing post, the first local publication to report on the grocery store being named Seiwa Market:
In other grocery news, Seiwa Market is now open at 1801
South Dairy Ashford, and there are plenty of promotions and giveaways to
be had on opening day, which is Friday, April 1. The Japanese grocery
will also have a food court, including a sushi bar and Ichi Ramen Bar.
But the information was wrong due to lazy reporting. Seiwa Market’s Facebook for Houston showed updates for weeks of the California location opening and scrolling through the visitor posts the store replied it’s opening around May. After someone visited the Houston location only to be disappointed by the wrong information Houston Press presented, the author amended the post adding this update:
Updated 4/3/16, 3:505 p.m.: It turns out that Seiwa’s very ambiguous opening announcement was
for its L.A. location, which we only learned after a tip from a
disappointed reader. The grocery said that it anticipates a July opening
for the Houston store.
