Online or Real
Hogyokukai is a pioneer in online. The classic dojo has a large monitor and is connected to dojos in Japan and abroad.
In addition to regular training, each branch also has online training on different days of the week, or if you cannot make it to the dojo, you can practice from home by connecting to the dojo. Training at the Sohonbu dojo is basically distributed online to all members, so in areas where there is no dojo, you can participate in Sohonbu training, mainly online.
People from overseas can also learn online and use English.
If you live in Japan, you can use both online and real dojo.
There are examples of people who have become successful and have become place heads or branch heads.
