Limited people per day for Yoshida trail

We are coming from oversea, I noticed you start to limit 4000 people on mountain per day, do we need make reservations for specific day for climbing Yoshida? If so, how and where to make a reservation? Please respond to me and thank you very much.

If you make a reservation at a mountain hut, then you can climb the mountain regardless of daily limits.

Also, the limit is unlikley to be exceeded on most days except the really busy days, such as the Obon period in mid August and weekends. If you visit during regular weekdays - which is recommended anyways - it is unlikely that the limit will be exceeded.
