Information Dutch IOGKF Gasshuku 2024

Dear reader,

Here is additional information about the Dutch Gasshuku 2024, organized by the IOGKF Netherlands.

The gasshuku

On 13 & The time has come on April 14, when the IOGKF World Chief Instructor, Sensei Nakamura, 8th dan, who lives in Canada, and the Okinawa resident IOGKF Chief Instructor of Japan, Sensei Yamashiro, 8th dan, to the Netherlands, for a two-day training internship.

This is a unique opportunity to gain deep experiences and insights into Okinawa goju-ryu karate. Many have experienced both teachers before. In the Netherlands or abroad. For me they are still important sources of inspiration, valued colleagues and good friends. They both have a mature and unique way of conveying the essence of Okinawa goju-ryu karate. I will also teach myself and do my best to make a worthy and meaningful contribution.

Furthermore, the gasshuku is also a great opportunity to spend time with acquaintances from home and abroad.

For whom?

This event is organized by and for the IOGKF Netherlands. It is open to karatekas who train at one of the dojos affiliated with the IOGKF Netherlands or at IOGKF dojos in Abroad. The minimum age for participation is 16 years.

On Friday they will also teach youth in Tiel, but that will be organized separately.


You can register at this page. There is also the option to register for a joint buffet [see below].

For the quick booker there is the opportunity to save costs on the ticket price. The early bird discount ends on February 15.

Training for one day is possible, but not recommended. It is recommended that you register for the two full days to experience the full experience of a ‘gasshuku’. That’s a really different experience than just taking a few training sessions.

If there is a storm, people who book for the entire weekend will be given priority.

Registration for the gasshuku closes on Wednesday, April 10.

Tickets and information about T-shirts will also be added before the end of February.
