MAMMA Onigiri
A Taste of Japan Made with Love
MAMMA Onigiri – A Taste of Japan Made with Love
Onigiri isn't just food, it's comfort, culture, and care all rolled into one.
In Japan, onigiri (rice balls) are more than just a quick snack. They're the warm, hand-shaped meals moms make for their children. They're what you bring on school trips, eat during lunch breaks, or grab on the go when you need something wholesome and satisfying. And now, you can experience that same love and care, fresh from Japan, through MAMMA Onigiri.


Do you know ONIGIRI BONGO?
It is probably the most famous ONIGIRI store in Japan, with a line as long as 200 meters. Of course, this is because many curious and bored people come to this shop because it was featured in a Japanese TV program. But the essence of the shop is different.

Inspired by a Japanese Icon
If you know Onigiri BONGO, you know it's no ordinary shop. It's legendary, famous for its massive queues, freshly made onigiri, and a menu with over 50 fillings. People wait in line not just for the food, but for the feeling.
MAMMA is the next chapter in that story. Developed from BONGO's philosophy and upgraded for global franchising, MAMMA brings the magic of onigiri to the world, with a modern twist.
So, What Makes MAMMA Special?
- Always fresh, always warm
Each onigiri is made with steaming hot rice, lightly salted, and shaped by hand. It's simple, satisfying, and made with love, just like Mom used to make it.
- Over 50 fillings (and counting)
You'll never get bored, from sour plum (umeboshi) to grilled salmon, karaage chicken, and even vegan or seasonal options. You can even mix two fillings in one rice ball!
- Eat in or take out your way
Want to enjoy onigiri at the counter or take it with you? MAMMA is designed for both. Every item is made fresh and sold slightly warm, and takeaway orders are best enjoyed within 180 minutes.
- Gluten-free, vegan, and halal-friendly
Whatever your dietary needs, a delicious MAMMA onigiri is waiting for you.

In Japanese, "mamma" means both rice and "mama." It's the warmth of home, in every bite.
