For room entry, in addition to the regular self-service reception machine, you can use the instant entry function "SuguKara" on the official Jankara app. From room reservations before arrival to extension procedures and payment, everything can be completed on your smartphone or in-store terminal.

We have created a space that is easy to use for customers who "feel a little uncomfortable asking staff for help" or "want to enjoy at their own pace."

Since there is no staff entry, you can spend private time without hesitation. No front desk procedures are required upon leaving, allowing for a smooth experience until the end.

Additionally, although it is a compact store with 19 rooms, soft-serve ice cream is available for free. Furthermore, "all-you-can-eat french fries," perfect for group use, are available as an additional order. We also offer a variety of easy-to-enjoy menu items for breaks between songs.

Enjoy More Than Just Karaoke with Mirroring & Blu-ray Rooms

All 19 rooms are equipped with mirroring functionality. You can project your smartphone screen onto the large monitor to enjoy live performances of your favorite artists, movies, and more on a big screen with loud sound.

Furthermore, some rooms are equipped with Blu-ray players. After enjoying high-quality video, you can then sing the artist's songs or theme songs in karaoke, allowing for various ways to enjoy your time in one space.

Free Wi-Fi and chargers are also provided, so you can relax without worrying about data usage or battery life.

About Jankara

Since starting our karaoke business in 1990, we have expanded our business by offering all-you-can-sing, all-you-can-drink, and transparent pricing, which have been well-received by customers.

We have developed concept rooms that are unique to our company, opened new stores with a full store concept, and in addition to private rooms, we also have open counters and BAL UTAO where customers can communicate with each other in open spaces. Currently, we operate over 200 stores nationwide as the largest karaoke chain in Western Japan.

In recent years, we have also promoted DX (Digital Transformation) and were the first in the industry to introduce unmanned reception and payment machines in all stores to pursue highly convenient services.

We have also equipped our official app with "SuguKara," an industry-first function that allows reservations, check-in, and payment with just a smartphone. In addition, we have introduced food and drink ordering functions and song selection functions, realizing a next-generation karaoke experience where everything can be completed within the app.

While constantly creating new value, as an "AI-native company" promoting the company's overall strategy of "To→AI," which embodies our company name TOAI, meaning "moving towards the AI era," we will continue to challenge ourselves to create karaoke spaces that customers have never experienced before.
