Hatori Jinja Shrine is located to the east of Masumida Jinja Shrine’s main hall, from where Ichinomiya's name (literally meaning "Primary Shrine") originated, and Hatori Jinja Shrine's god of textiles is the mother of the god enshrined in Masumida Jinja Shrine, Ame no Hoakari no Mikoto.

This festival started in 1956, and is held for four days starting from Thursday and ending on the last Sunday of July. Based on the legendary characters of Orihime and Hikoboshi from the Tanabata Festival legend, who are often associated with textiles, the whole city joins in on this "Textile Thanksgiving" Ichinomiya Tanabata Star Festival, the largest summer festival in the city. With traditional streamer decorations fluttering in the shopping streets, and gorgeous decorations made by the local people, the festival is praised as one of the three major star festivals in Japan along with the Sendai Tanabata Star Festival and Shonan Hiratsuka Tanabata Star Festival, and welcomes over one million visitors every year.

During the festival, there are all sorts of stage events, special stages, and event booths all around Masumida Jinja Shrine, Hon-machi Shopping Arcade, and Owari-Ichinomiya Ekimae Building (i-Buil). There are many events involving the participation of local citizens, such as the bon dance, etc.
Every year, the festival invites special guests for talk shows and live performances to spice up the atmosphere.
