About this case study
We delivered AI training to Daiki Tajima, Business Director of SENN Hotel Group (Niigata, operating 5 properties as of May 2026). The training works through the writing tasks that come up every day in running inns, finishing each piece together with AI, from first draft to final copy.
The words and numbers on this page come from an interview with Mr. Tajima about one month after the training began.
Frequently asked questions
What changed at SENN Hotel Group after the AI training?
About one month in, the number of inns one person can handle grew from 5 to 15, by Mr. Tajima's own estimate. He also said that quality did not drop but rose, and that he can now make time to sit down with the owners.
Who measured the "5 to 15 inns" figure, and how?
It is not a third-party measurement. It is the estimate Business Director Daiki Tajima himself gave in an interview about one month after the training began, published as he said it.
What kind of work is AI used for?
Mainly the writing tasks of running inns. Claude works alongside the team from first draft to final copy, widening the capacity to look after several properties in parallel.
