At Midsummer, Tamura sensei holds a seminar in Malmo, Sweden. Saturday June 21 - Sunday June 22. Lodging is free in a nearby gym hall, but there are also hostels and hotels, if you prefer.
No need to pre-register for the seminar - just pop by
Here is the seminar poster, with additional information:
Malmo is in the south of Sweden (near Copenhagen), so we have no midnight sun, but at Midsummer the days are still long enough, I can assure you.
