Ikebukuro Seibu will host a Sushi, Bento, and Delicacies food fair from Friday, January 6 – 18, 2012 on the 7th floor. (Note that the event closes at 6 p.m. on both the 12th and 18th.)
Regional food and sake from throughout Japan are available. Highlights include sushi from Ginza Kyubey (Jan. 6-12) and ramen from Machida 69’N’ ROLL ONE (Jan 13-18). Both are among the best in their categories. The ramen should be worth visiting as Ikebukuro is much closer to the city than traipsing out to Machida.
A variety of sweets as well as sake and shochu.
The sales flier for the event (in Japanese – but great photos).
My list of Tokyo’s best depachika.
