Seaweed-wrapped rice balls were born in Tokyo — taste the history where onigiri met nori.
Last updated: 2026-04-19
Introduction
Rice balls, or onigiri, have existed in Japan for over two millennia — born as a clever way to carry cooked rice. Even today, they remain a lunchbox staple for school trips and family outings. In Tokyo’s Togoshi-Ginza, Onigiri Togoshi-ya stands out for its dedication to rice quality, drawing both locals and travelers in steady lines. On my visit, they used “Haenuki,” a fragrant rice from Yamagata Prefecture known for its soft but structured texture.
My Memory
When I was in elementary and junior high school, onigiri was the absolute rule for field trip lunches. It was the same for every family. The standard fillings back then were pickled plum (ume), okaka (bonito flakes seasoned with soy sauce), salmon, and cod roe (tarako).
The change came in the 1980s as convenience stores began to spread across Japan. They sold rice balls with fillings we had never seen at home. "Tuna Mayonnaise," which is now a standard flavor, was shockingly innovative at the time. I remember how we all used to buy and snack on them after school.
💡 Did You Know?
The "Crispy Nori" wrapper is a Japanese invention!
When you buy an onigiri at a Japanese convenience store, you'll notice a plastic film separating the seaweed from the rice until the very last moment.
This packaging was invented in the late 1970s, driven by the Japanese obsession with enjoying crispy, aromatic nori anytime, anywhere. Pulling the wrapper sheet and wrapping the seaweed with your own hands right before eating—this little "ritual" has now become an essential part of modern onigiri culture.
What to Try
- Onigiri Set (with miso soup and karaage)
Choose one or two rice balls — they’re large enough that one is plenty for most people. With over 45 fillings available, you’ll find both classics like ume (plum), salmon, and tarako (cod roe) and creative seasonal options. The shop doesn’t salt the rice, making pickled vegetables an ideal pairing. The one in the photo is filled with Nozawana pickles. - Miso Soup Upgrade
The standard version features seaweed, but you can pay extra for nameko mushroom miso soup — slippery, earthy, and rarely found outside Japan. - Karaage Fried Chicken
Crispy, juicy, and perfectly matched with rice. - Takuan Pickles
In Japan, side pickles called “hashi-yasume” refresh the palate between bites. Takuan, made from daikon radish, is the quintessential example — nibble it slowly as you eat.

Seaweed-wrapped rice balls were born in Tokyo — taste the history where onigiri met nori.
You might assume that seaweed-wrapped rice balls have always existed — but that idea was born in Tokyo. Nori seaweed cultivation began in Edo (modern Tokyo) during the 17th century, where it first met the rice ball. The union of rice and seaweed shaped the onigiri we know today. For a taste of this history, enjoy one right here in Tokyo.

About "Taste of Japan"
Hello, I'm Yuta.
Born in landlocked Yamanashi and having lived in the gourmet city of Sendai for 10 years, I now call Togoshi-Ginza home. My frequent business trips across Japan allow me to constantly explore the diversity of regional flavors.
Why Togoshi-Ginza?
This street is Tokyo’s longest shopping arcade (about 1.3 km), but it holds a special history. It was the very first street in Japan to adopt the "Ginza" name—a tradition that later spread across the country—after receiving bricks from the famous Ginza district following the 1923 Great Kanto Earthquake.
My Wish as a Local
I am not a culinary expert. However, as a Japanese local who knows both the convenience of Tokyo and the origins of regional food, I want to share the "atmosphere" and "personal feelings" that you won't find in standard guidebooks.
The Concept: "Tokyo or Trip?"
Visiting every region of Japan in a single trip is nearly impossible. Some food experiences are worth the travel to the source, while others offer a fully satisfying experience right here in Tokyo.
This blog is a guide to help you make that choice. Based in Togoshi-Ginza, I share my honest experiences and "my personal answer" to help you maximize your culinary journey in Japan.
