**Important: when driving, don't go onto the ramp! Follow their signs with a cute logo. Both google and apple maps took us onto a main road that continued through the mountains. It took us a while to turn around.** Oyako-an was beyond our expectations! We were in the area trying to find somewhere to eat during Golden Week, and I happened to find this place on google maps with high ratings. The ratings do not lie, we loved our experience here! First of all, this place is very foreigner-friendly. The menu also is in English. For a place that's quietly tucked away in the mountains, it was surprising how much English they knew. For Golden Week, it was surprisingly not busy so we enjoyed talking with everyone there. The service and hospitality was so warm and amazing! Next, the food. Wow! It was too good. We ordered the yakiniku set and the wagyu steak set. The Asso wagyu meat tasted GREAT! And as a set meal, I was really happy with the meal altogether. The side dishes were so carefully picked, it was one of the most balanced set meals I've had. Every single part of it was delicious. This was one of my favorite meals I've had in my life :)

The boss of couple are very friendly, and the food is absolutely delicious. The beef melts in your mouth and has a rich oily flavor! If I pass by the area again, I will definitely visit this hidden gem. I highly recommend this place with a perfect 10 score!

I don't know how to thank you, so I'm sending my heart here. I'm so sorry and thank you to all of staffs and other customers for helping us to pull my car out in the heavy rain yesterday. I think it will be an unforgettable event and memory for the rest of my life. Also  I really enjoyed the food. Foods were great and sauces were so good. Thanks to you, I was able to finish my trip safely and came back to Korea safely as well. If I have a chance, I'd like to go back to see you. Thank you so much once again. 誠にありがとうございます.

The best food in Aso. This restaurant is owned by a family with full of love. The boss is very friendly and helpful also cap speak English too. The Wagyu steak and fried pork are very delicious. Highly recommended. We will visit again when we travel to Aso.

Had an amazing meal here, the beef curry was incredible. Restaurant is run by a very nice couple who is super friendly and helpful. There are signs for the restaurant on the road but just be aware it's tiny roads across rice fields but that will get you to the right spot!

We found this place by the high rating on Google maps and it is beyond our expectations! Food is extraordinary good. Taste original with the use of local produce ! We had Takana ( Japanese vegetable) fried rice and Aso beef steak set, Beef is ranked as A5! Not just the beef is perfectly seasoned and cooked but all the sides are full of surprises as well! The original steak sauce taste so good that we purchased a bottle! I never knew Takana fried rice before but now I know it's something I want more. Would recommend everyone to have it. The owners of the Oyako-an are very friendly and welcoming too! Would definitely come again if I visit Aso again! A lot of signs showing the directions of the restaurant along the road too. Looking forward to the next visit! ごちそうさまでした！

One of the best Japanese food I ever had for my trip. The main room is a bit small with 3 tables only. We got lucky that a table became empty after arriving for 10mins. The owners are passionate and smile very nicely. Food is great. Udon’s soup is specifically made. Fried pork has very good texture. The Wagyu beef is close to A4. The cheese rice is great. Overall the experience is great. Only would recommend driving because I don’t find it convenient for walking or taking bus.

The best food around! The family that runs it truly love what they do. The food.. The sauce.. there's no wrong choice here. Don't let the drive to it dissuade you. The flavor is next level. Thank you for a fantastic meal!

Incredibly kind couple who owns this spot. This was a great place to eat at after a long day of hiking and onsen. We had the tonkatsu and pineapple juice and the tonkatsu was very well breaded. Such a delicious meal and a very kind, comfortable environment

Amazing quality of meat and their home made sauce is great. Service was also top tier!

TLDR: Food is AMAZING. Highly recommend. TL: We saw high ratings on Google review and decided to drive there for lunch after visiting Mt Aso. We reached there while questioning ourselves if we were in the right place as it was tucked behind some fields. We got the steak and yakiniku sets and were blown away by the food quality. Steak cubes were literally melt in your mouth and the miso soup was hearty. They also served us their version zenzai that had cheese in it and that was super delicious as well. We also had a refreshing pineapple vinegar drink that helped to digest the food. Service was really good and made us feel right at home even though we were the only ones there.

おいしかった ! Excellent ! Owners are lovely and food is really good 🍲 If you come to Aso, don’t hesitate to come here

Not only the food is really good, but the owner go above and beyond to make you feel at home. We happened to visit for Mother’s Day and we got a free drink and おつまみ

Highly recommend. Really tasty! It’s worth to take time to find the restaurant.

We had a wonderful dining experience at oyako-an! The owners were so kind and lovely and the food was excellent! I highly recommend the yakiniku (with their sauce!!). My friends had the fried chicken and the steak dishes and loved them! When we come back to the area we will definitely return!!

Really fantastic find in the Aso area. A bit out of the way and in a residential area, but parking is available at the end of the road. Food was tasty but the real value here are the owners. They were incredibly kind and it really felt like we were eating with family. The menu has English translations and the food is plentiful. If we are ever in the area again we'll definitely return!

Wow! The most friendly and sweetest couple ever. Great food and a really good selection. What a gem!! Warm welcome and an even more friendly goodbye. I really hope I get to go back one day

Great little family run restaurant very close to Aso Farm Land! The food is cooked to perfection, and to your preference, so it tastes amazing. If you're vegetarian, you can have the bibimbap, and the menu is in English and Japanese. Highly recommended if you're in the area, will definitely go again!
