Read the dialogue "Japanese house". Todd talks about his house in Japan.

Meg: Hey, Todd, where do you live?

Todd: I live on the east side of downtown.

Meg: Oh. Do you like it there?

Todd: I do. I live in an older house. But it's a big house, and it's really relaxing. It's a nice place to live.

Meg: Wow. Sounds nice. How many rooms does it have?

Todd: My house is pretty big. It's four rooms. It has a big sleeping room. It's a Japanese house. So it's not really a bedroom because you sleep on the floor.

Meg: Oh.

Todd: But it also has a living room. It has, like, an office room and it has a kitchen.

Meg: Is it a big kitchen?

Todd: No, it's a pretty small kitchen and it's a very old kitchen. I have a small stove. So it's very difficult to cook. But, you know, I have a refrigerator. I have a microwave. I have a nice kitchen table to eat at. So it's a pretty decent kitchen.

Meg: It sounds okay. What about your living room? What do you have in the living room?

Todd: My living room, it's pretty cool for a guy because it's a good place to watch sports. I have a really big TV, and I have cable TV, so I get all the football channels.

Meg: Nice.

Todd: And I have a really big sofa, so I can sit on my sofa and watch sports and drink something. It's great.

Meg: Sounds relaxing.

Todd: Very relaxing.

Meg: Well, do you also have a nice bathroom?

Todd: I do. I actually have three bathrooms.

Meg: Oh, really?

Todd: It's kind of crazy, yes. So in English, we say bathroom, but I have two rooms that are for the toilet and I have one room or the bathroom with the toilet for the guests. And then I have a bathroom that I use. And then also I have a natural hot spring bath outside my house. So if I want to take a shower or bathe, I use that room.

Meg: Wow. I'd love to have a hot spring at my house.

Todd: Yeah, it's very nice. It's very, very nice.

Meg: Does your house also have a yard?

Todd: It kind of has a yard. So outside my house, there's an area for flowers and bushes. And it's like a yard or a garden around the house, but it's not a place you can play sports. There's no grass or anything. So it's a very, very small yard. But, you know, it's a nice place.

Meg: Oh yeah. It sounds like a nice place to live.

Todd: It is a nice place to live. I'm very, very lucky.

Meg: You said you have a sleeping room, not a bedroom. What does that mean?

Todd: Yeah. I live at a Japanese style house. So it's called the tatami room. And you sleep in the tatami room and you sleep on the floor on a futon. So I don't have a bed. So it's not a bedroom. It's a room that you sit in during the day and you can eat and talk with guests. But it's also a room that you sleep in at night. So yeah, I call it my sleeping room.

But I think in Japan, they just call it the tatami room.

Meg: Is it comfortable sleeping on the floor?

Todd: Yeah, it's really comfortable. Now I love it. So before, I slept on a bed. But now I sleep on the futon on the floor and I really like it. Actually, I prefer to sleep on the futon on the floor.

Meg: Well, it sounds like your house is really comfortable.

Todd: It is. It is. I never want to leave.
