"It was my first time checking into a hotel without staff on site. The hotel will send you an email with an entry code to get into the lobby. Once inside, there's a tablet you use to check in. After you snap a photo of your passport, you get connected to the hotel staff via video call to verify your identity. Then you will get your room code on the screen. Take a picture of your room code with your phone. The hotel is very roomy and very close to the station. "

The room was spotless and had all the amenities you could need.The staff were very friendly and helpful, and were prepared to deal with a language barrier. It even has laundry and free light meals that were quite good! And all for a great price. Next time I'm in Karatsu this will he my go-to."
