i checked out ur link and its based in kyoto.
and its looks like they only do outcall, no site map or whatever everything is just done by the phone(or so i assume)
this is just an EXAMPLE of the conversation that i had experienced or what i would probably do.
in some cases they want to clarify if its your first time, where did you learn about the place, do you know the rules and regulations etc.
so for me here is the easiest way to handle the conversation:
case (1)
SHOP: hai moshi moshi/ hello
YOU ; garuzunetowa-ku desuka?/is this girls network
SHOP: hai, sou degouzaimsu / yes it is
YOU: (the name of the girl) wa aitemsuka?/is(the name of the girl)available
SHOP: hai aitemsu yo / yes she is available
YOU: jya (the name of the girl) de onegaishimasu/<-- this is self explanatory so i guess its ok not to translate this part
SHOP: nan pun co-su desuka or co-su wa/ which course will you be availing
YOU: (the course)desu
SHOP: hoteru wa go kimaru desuka/ have you decided which hotel will you be staying
YOU: hai, ima (hotel name) no (room num) go-shitsu ni imasu<--- always say the go-shitsu after the room number for example 102 - in japanese ichi maru ni go-shitsu ni imasu.
SHOP: (he'll be reapting what you said, hotel name room num etc then)hai kashukomarimashita, korekara onna no ko wo ikasemasu no de 10-20pun omachishitekudasai/the girl will be on her way pls wait 10-20mins
case(2)
SHOP: go renraku arigotougozaimasu, garuzunetowa-ku de gouzaimusu / thank you for calling this is girls network
YOU: (the name of the girl) wa aitemsuka?/is(the name of the girl)available
SHOP: hai aitemsu yo / yes she is available
YOU: jya (the name of the girl) de onegaishimasu/<-- this is self explanatory so i guess its ok not to translate this part
SHOP: nan pun co-su desuka or co-su wa/ which course will you be availing
YOU: (the course)desu
SHOP: hoteru wa go kimaru desuka/ have you decided which hotel will you be staying
YOU: kore kara hoteru ni hairimasu/ im on my way to the hotel now
SHOP: hoteru wo go kimari ni natara go renraku kudasai/pls call once you got inside the hotel.
-end of conversation-
-call again once your inside your room-
YOU: hai, ima (hotel name) no (room num) go-shitsu ni imasu<--- always say the go-shitsu after the room number for example 102 - in japanese ichi maru ni go-shitsu ni imasu.
SHOP: (he'll be reapting what you said, hotel name room num etc then)hai kashukomarimashita, korekara onna no ko wo ikasemasu no de 10-20pun omachishitekudasai/the girl will be on her way pls wait 10-20mins
if you cant handle the conversation on the phone chances are you wouldnt have a good time with the girl or worst everything might get cancelled since you cant speak the lingo.
kudos to you
