おむすび一番 池袋東武百貨店 at Ikebukuro, Tokyo

A fresh onigiri and bento counter in Tobu Ikebukuro's basement, with a lunchtime build-your-own rice-ball option.

Omusubi Ichiban holds a tidy spot on the B2F food floor of Tobu Department Store Ikebukuro, hand-shaping rice balls from fresh ingredients throughout the day. The counter is known for its variety, from classic shio and salmon to seasonal specials such as edamame and kombu, and the rice keeps its gentle flavour and texture even under the simple fillings. A lunch-only customise-your-own onigiri option lets regulars pick their fillings, while onigirazu and ready-made bento boxes round out the takeaway line-up. A daily-changing onigiri set is also available through the department store's online shop, handy for a quick dinner pick-up on the way home. It suits office workers and shoppers after a light, honest lunch. Simple, reliable and genuinely fresh, Omusubi Ichiban does one thing - rice balls - and does it with quiet care. The staff shape each one to order, and the rotating seasonal menu gives regulars a reason to keep coming back. It is a small, friendly counter that earns its place in a busy food hall.
