Answer the front desk phone in Japanese, and in English for guests
The agent speaks polite Japanese by default and moves to English when the guest does.
The agent asks for the name and check-in date, checks the new dates against availability and reads them back before it changes anything.
The agent changes the booking only after the guest agrees, then repeats the new dates.
A guest who needs English can ask at any point. With language detection on, the agent follows and keeps the booking details.
The agent doesn't handle complaints or access requests. It tells the guest it is connecting them to a person and transfers the call.
What a Japanese guest expects to hear
A Japanese guest expects polite speech, their name with the honorific -sama, and a stated purpose for any data you take. Check these before you publish.
Formality
The instructions ask for polite Japanese in the desu/masu form (です・ます). Test the level of formality your hotel uses, including how the agent says a guest's name and the dates, and have a fluent reviewer check the wording of requests.
Japan
Japan's Act on the Protection of Personal Information asks a business to tell the person the purpose of use once it has their personal information, or to publish it. A guest's name and booking are personal information, so state the purpose in your greeting or on your site.
This is general information, not legal advice. Ask counsel in Japan to review how the greeting states the purpose of use.

Japanese call center FAQs
What is an AI Japanese call center?
A phone line your business runs where an AI agent, not a room of staff, answers the calls that come in Japanese. Here it is a hotel front desk: Yamamoto changes bookings from the dates your system returns and transfers anything else to staff. It is software you set up, not a call center job.
How much does an AI Japanese call center cost?
Each agent minute is $0.03, plus telephony and LLM usage, at one rate for every language. See pricing.
Does it speak polite Japanese?
You ask for it in the instructions, for example the desu/masu form, and the agent follows. Test the register your business uses with a fluent reviewer, since keigo is a matter of fine detail.
How does it compare with an outsourced Japanese-speaking call center?
Yamamoto handles booking changes and check-in times, the calls this setup has tools for. Complaints, access requests and anything off the script still need a person, at your front desk or at an outsourcer. An outsourced center prices the Japanese speakers it staffs for you, often per agent hour, so get its quote. The AI agent is billed by the minute it spends on calls: $0.03/min, plus telephony and LLM usage. People can improvise outside a script and the agent cannot, so plan who takes the transferred calls.
Can it switch between Japanese and English?
Japanese and English are both in the set that language detection covers. It is a Beta option in the agent's speech settings, and switching it on changes the speech recognition model the agent uses. Run calls with real guests, including non-native English speakers, before you depend on it.
What does the sample line demonstrate?
A Japanese call from start to finish. The sample line holds one language per call, so it won't move into English. That needs language detection (Beta) on your own agent, which listens with a different speech model.
Does it connect to my booking system?
Through webhooks to your property management or reservation system, one for each tool on the card. Someone on your side who can code connects them once. Cartesia has no built-in hotel system connector.
Can it handle an emergency call?
No. Yamamoto handles booking changes and check-in details and nothing else, so a guest with an urgent problem goes to the front desk by transfer.
