If you’ve ever craved a truly satisfying Japanese meal that balances generous portions with top-tier flavours, then this ongoing dining promotion by Onkei Tonkatsu in Singapore may be just what you’ve been waiting for. Running from 1 April to 29 September 2025, the well-loved Japanese eatery is now offering a value-packed $39.90++ UPass Set Meal, perfect for sharing. Available at two convenient locations — Paya Lebar Square and ARTRA at Redhill — this special promotion delivers a hearty feast that combines quality ingredients, crispy katsu, and classic Japanese sides in a well-rounded and affordable set.
For those unfamiliar, Onkei Tonkatsu has steadily built a loyal following for serving some of Singapore’s crispiest and juiciest tonkatsu. Their focus on traditional Japanese frying techniques, high-quality breading, and carefully selected proteins has made them a go-to spot for katsu lovers. And with this limited-time UPass Set, they’re making it even easier to enjoy an indulgent Japanese lunch or dinner without overspending.
Let’s unpack exactly what makes this promotion worth your attention — and perhaps even a detour during your next shopping trip or work lunch break.
What You’ll Get in the $39.90++ UPass Set
For just $39.90++, you’re getting an entire spread designed for two people. The set includes:
-
2 Ebi & Rosu Katsu Sets – Each diner can choose between pork loin, fish, or chicken. This flexibility is a big win for mixed dietary preferences, whether you’re after a hearty meat option or a lighter seafood variant.
-
2 pieces of Tori Karaage – Crispy and flavourful, these Japanese fried chicken bites are always a crowd-pleaser.
-
2 pieces of Fried Oysters – Golden and juicy, they offer a touch of indulgence to round off the set.
-
2 full sets of rice, pickles, soup, and shredded vegetables – These complete the meal in true Japanese fashion, ensuring you walk away satisfied.
For under $20 per person before taxes, this is a fantastic value given the range and quality of food served. The deal is especially good for couples, friends meeting for lunch, or even two colleagues looking for a good meal that doesn’t break the bank.
Why You Shouldn’t Miss This Deal
1. Exceptional Value for Authentic Japanese Cuisine
Japanese meals in Singapore often come with a premium price tag, especially if they involve seafood or fried dishes. With this UPass Set, Onkei Tonkatsu is delivering an authentic katsu dining experience at a fraction of the typical cost. Think about it — for less than $40++, you’re getting mains, sides, and even soup for two. That’s the sort of price usually reserved for casual fast-food, not carefully prepared Japanese dishes in an inviting restaurant setting.
2. Quality Ingredients with Variety
One of the highlights of this promotion is the ability to customise your set with different protein options. The pork loin (rosu) is juicy with just the right amount of fat to deliver full flavour, while the fish and chicken options cater to those who prefer leaner cuts. Add to that the crunch of the fried oysters and the savoury bite of karaage, and you’ve got a meal that doesn’t feel repetitive or limited.
The sides — rice, pickles, shredded vegetables, and miso soup — are more than just fillers. They balance out the fried items and make this set feel like a complete, nutritious meal rather than just a plate of indulgence.
3. Perfect for Casual Dining with a Friend or Partner
With Singapore’s dining scene becoming increasingly expensive, it’s refreshing to find a sit-down restaurant offering genuine value. Whether you’re catching up with a friend, having a casual date, or simply taking a break from your day, the relaxed environment at Onkei Tonkatsu makes it easy to unwind over a hot, freshly-prepared meal.
Both the Paya Lebar Square and ARTRA Redhill locations are centrally located, easily accessible by MRT, and ideal for shoppers, office workers, and residents alike.
4. Limited-Time Offer – Encouraging Repeat Visits
While the UPass Set is available till 29 September 2025, this isn’t a promotion to delay. Deals like these tend to generate a lot of buzz and foot traffic. Considering the flexibility and affordability, don’t be surprised if you find yourself going back more than once during the promotional period — especially if you’re trying all the different protein combinations.
A Great Choice for Group Outings
This UPass Set isn’t just suitable for couples — if you’re out with a small group or your colleagues, simply order multiple sets and share. The variety offered in this promotion means everyone gets to sample a bit of everything. With the combo of crispy meats, seafood, and vegetables, you’ll get a good balance of indulgent and light elements in one meal.
