In Japan, the time period of January is called “oshougatsu,” especially from January 1st to 7th.
Oshogatsu is one of the most important events of the year for Japanese people.
During oshogatsu, family members go back to their hometown and gather together with relatives,to celebrate the New Year. It's the equivalent of the Christmas holiday season in western countries.
I want to eat the cheap food, because I eat luxurious food for Oshogatsu.So I ate a hamburger.
Umaibou has teriyaki burger taste.
It tastes of a little mustard for teriyaki source taste.
