DMM didn't give you a lesson until 2015 during the Chrismas season and the period before and after New Year's Day, but we have heard a lot of valuable and instructive advice from customers. For that reason, after careful consideration, we decided to give a lesson during the period of 2017 as we did last year. However, we expect a lot of teachres will take holidays during the period. We are going to ask teachers all over the wold to give a lesson so that all of you can take a lesson, but it is probable that all the lessons will be booked earlier than usual. We hope you will soon book lessons because the lessons are not large in numbers. ※If all the lessons are booked on the day, we are not going to issue tickets to take extra lessons.
