HIKAKIN, one of Japan’s best-known YouTubers, has released a new drink under his tea brand ONICHA: ONICHA Corn Tea.
The 600 ml bottle has a bright yellow cap and a playful label featuring ONICHA’s oni-inspired mascot, Onippi. It is easy to spot in the refrigerated drink section at 7-Eleven stores in Japan.
I tried it myself and found that the roasted corn aroma was surprisingly noticeable. However, it did not taste overwhelmingly like corn. It also reminded me slightly of Japanese barley tea, or mugicha, making it light and easy to drink.

My Honest Taste Review
A Noticeable Roasted Corn Aroma
The first thing I noticed after opening the bottle was the roasted corn aroma. The fragrance is distinct enough that you immediately know this is corn tea.
However, the flavor is not as intense or heavy as corn soup. It does not feel as though the taste of corn is overpowering the entire drink.
The aroma is clearly corn-like, while the tea itself tastes clean and refreshing. The finish is light, so it should also be easy to enjoy with a meal.
It Reminded Me Slightly of Japanese Barley Tea
What surprised me most was that ONICHA Corn Tea reminded me a little of Japanese barley tea, known as mugicha.
It does not taste exactly the same, but both drinks have a pleasant roasted-grain aroma and a clean finish. If you already enjoy mugicha, this corn tea may feel quite familiar and approachable.
Even if you are worried that corn tea might taste too strongly of corn, this version is easy to try. It has enough roasted corn character to be interesting without becoming too rich or unusual.
Caffeine-Free and Easy to Drink
ONICHA Corn Tea contains no caffeine.
That makes it a convenient option for lunch or dinner, while studying or working, or when you want a roasted tea in the evening. The 600 ml bottle is also a useful size for carrying around during a day of sightseeing in Japan.
Check the Label for an “Oni-Mikuji” Fortune
There is also a small surprise hidden behind the bottle label.
After finishing the drink, peel off the label to reveal an Oni-Mikuji, an oni-themed version of a Japanese fortune slip. There are four possible fortunes, including one secret design.
It is a fun little feature, especially for visitors looking for a uniquely Japanese convenience-store drink.
Limited ONICHA Sticker Campaign at 7-Eleven
From October 3 at 10:00 a.m. to October 17, 2026, participating 7-Eleven stores are offering a limited ONICHA sticker promotion.
Buy any three eligible ONICHA drinks in a single purchase and you can choose one original sticker from five designs. Each store has a limited supply of 50 stickers, and the promotion may finish early when all stickers have been claimed.
