Tourists in Japan usually go to see traditional Japanese buildings but there is a new tourist attraction and it's a very modern and unusual building.
Welcome to the Henn Na Hotel - it's a new hotel and a very unusual one. A s tall robot protects the door and then a pink doll robot welcomes visitors when they come in. She's very friendly. There are two receptionists. The big question is - do they speak English?
"Kon'nichi wa. Do you speak English?"
The first receptionist is a woman with dark hair. She's wearing a smart uniform.
10 She's pretty and she's smiling but ... she's a robot too. And, no, she doesn't speak English.
So our visitor goes to the second receptionist. He's surprised! This receptionist is ... a dinosaur! The visitor pushes a button and he starts to speak.
"Welcome. Welcome to the Henn Na Hotel."
is It's English but it isn't very good unfortunately and it's quite funny.
"Thank you for your visitors."
He makes the visitor laugh, "On top of the filling the phone number, please put us to the bottom of the post. Please press to proceed with the send too." He welcomes the visitor and tells him what he needs to do. "Please move to 20 the right hand panel and check in." First, he must go to another machine.
- It takes a photograph of his face. I
The hotel rooms don't have keys and the doors use facial recognition.
"Thank you so much." Now our visitor knows his room number. What other surprises are waiting for him at this amazing hotel?

Here at the Henn Na Hotel, you don't need to carry your bags. A machine, not a person, carries them for you. It's called a 'portabot and it's clever but ... very slow! tn English the name 'henn na' means 'strange*- and it really ist Here there are only robots and machines, no people!
30 Finally, at the room, the visitor stands in front of the door and ... the door opens. It knows him because of the photograph from the machine in reception.
Inside the room everything is automatic. They want to save energy at the hotel. There are no light switches because visitors usually forget to turn as them off. There's a computer you can use. And of course there's also a speaking robot. She's called Churi Chan. You can ask her questions and give her orders. The problem is that she only speaks Japanese, so there's a book with translations.
Our visitor asks: 'What time is it now? and 'How is the weather today?' and 4 she tells him. Then he tells her to switch off the lights. She does. But then he has a problem - it's too dark to read the instructions to turn the lights back on again.
