TripX, an AI startup spun out of the University of Tokyo specializing in the accommodation and tourism sector (Headquarters: Yokohama, Kanagawa, CEO: Takuto Nishimura, hereinafter referred to as "TripX"), has launched "Tripbox Auto Reply Mail," a new product for its accommodation DX platform "Tripbox," for ryokans and hotels, starting April 7, 2026. This product was developed and commercialized through repeated verification in real-world settings at Hakone's accommodation facility, Hotel Okada, and aims to reduce the email response burden for accommodation facilities and streamline multilingual support.
**Background of Release**
In 2025, the number of foreign visitors to Japan reached a record high of approximately 42.68 million (※1), leading to an increasing trend in inquiry emails received by ryokan and hotel front desk and reservation staff. Hotel Okada, where the product's pilot test was conducted, received over 1,500 emails in a busy month (1,000 domestic, 500 international), about 33% of which required foreign language support (※2).
Meanwhile, the staff shortage faced by accommodation facilities is a structural problem. Over 70% (73%) of accommodation facilities report feeling a staff shortage (※3), and the active job opening to applicant ratio for service and waiting staff remains above the average for all industries (※4).
In such circumstances, responding to foreign language emails requires manual work for translation, confirmation of reservation details, and drafting replies from scratch. At Hotel Okada, email operations, including multilingual support, sometimes extended to over 4 hours a day (※2). Foreign language support tends to be monopolized by specific staff with language skills, and combined with the manual effort of differentiating emails from multiple OTAs per address, it led to delayed responses and inconsistent quality during peak seasons.
Foreign tourists rank "communication with facility staff" high among their travel difficulties (※5), and delayed or low-quality responses directly impact review scores and repeat visit intentions. AI-driven, on-site implementation support is needed to address this challenge, which cannot be solved by simply increasing personnel.

**Overview of "Tripbox AI Mail"**
"Tripbox AI Mail" is a product that allows accommodation facilities to handle email correspondence on Tripbox using AI by linking their current email addresses via IMAP or other methods. The generative AI, specialized for the accommodation industry, automatically generates reply drafts by referring to FAQs, in-house rules, and templates based on the inquiry content. Staff only need to review the content, make necessary corrections, and send it. Content edited in Japanese is reflected in multiple languages, reducing the burden of foreign language support.
Furthermore, the generative AI automatically learns each time staff edit a reply, so the more it is used, the more the facility's unique phrasing and rules are reflected, leading to continuously improved reply accuracy.
Details and usage examples of "Tripbox AI Mail" are introduced on the following page.
**Key Features**
① Instant generation of reply drafts by automatically referencing FAQs and templates
② Functionality for automatic accumulation and update of FAQs with each reply
③ Magic Edit for instant adjustment of replies with AI instructions
④ Simultaneous translation editor where Japanese edits are instantly reflected in multiple languages
⑤ Unified screen for team email management
**Results at Implemented Facilities**
This product was verified at Hotel Okada (Hakone, Kanagawa Prefecture, 122 rooms). Before implementation, an average of approximately 4 hours per day was required for email correspondence; after implementation, this was reduced to about 2 hours. This created about 30 hours of labor per month, allowing staff to allocate more time to core duties such as customer service and phone support.
TripX plans to roll out this product to inbound-focused and staff-shortage-plagued ryokans and hotels in general. It is particularly expected to be utilized by facilities where a small number of staff handle both front desk and reservation duties, or those with a high burden of multilingual inquiries.

**Comments from Personnel**
■ Takuto Nishimura, Representative Director & CEO, TripX Inc.
In the accommodation industry, there are significant challenges in balancing the efficiency of inquiry operations with response quality due to staff shortages and the increase in inbound tourism. "Tripbox AI Mail" was developed to support the reduction of email response burden and the streamlining of multilingual support in a way that can be seamlessly integrated into daily operations.
In a world where AI is increasingly advancing, we will provide its power in a readily usable form to ryokan and hotel operators.
■ Yohei Hara, Managing Director of Hotel Okada / Director & COO, TripX Inc.
At Hotel Okada, we handle about 50 inquiry emails per day, and previously, we spent around 4 hours on email correspondence. Inquiries from overseas customers, in particular, required significant translation effort, adding to the burden on our staff.
After implementation, the creation and translation of replies are now completed within Tripbox, greatly improving efficiency. Inquiries regarding cakes, esthetic treatments, and family baths, in particular, have become easier to respond to quickly, and I feel that staff have more time to dedicate to their primary roles in customer service.
I believe this tool can be beneficial to other ryokans and hotels facing similar email correspondence burdens.
**Inquiries and Consultations for Implementation Here**
For accommodation facilities considering implementation, we offer demonstrations and individual consultations.
To commemorate the launch, we are also offering a 1-month free trial and a 50% discount on the first year's usage fee for eligible facilities. Please contact us for details.
