I was seriously surprised recently, when following a keiko session as a guest in a London dojo, one of the members insisted on folding my hakama and keikogi and packing my armour. Taking this sort of trouble with senior kendoka is not unusual in Japan but almost never happens in the West. This individual is the student of a Korean sensei, so I can only imagine that Kumdo has similar reigi.
Anyone who has visited a Japanese high school or university dojo, even if only slightly more advanced than the students, gets this treatment. Having spent a number of years at the bottom of my own totem pole in Japan, I am used to being on the folding end of this deal, eventually having been promoted to chief back washer for one ninth dan and regularly having had to stop practise to bow to the departing Nissan Cedric of another.
Now to put this into context, I have never, before or after, washed the back of anyone of the same sex, but I understood the honour this represented and saw it as a great opportunity to say thank you to sensei. On the other hand, I still have a lifetime aversion to Nissan Cedrics.
There are of course cultural differences between East and West and certainly the confucian ethic of respect for age and experience is unique to Asia. We therefore do not spontaneaously show our apreciation of those that teach us in the same way as do oriental kendoka. A number of us who have either spent time in Japan or Korea, or have been trained by strict sensei may try to implement these courtesies, but many people do not understand what is expected of them.
I have often heard hachidan sensei being referred to by their family name without the addition of sensei, or even san and seen them having to wait their turn in the rush to use the shower. This must be a total shock to the system for someone who is used to being treated with immense respect in their home country.
So, my suggestion is that without trying to be what we are not, we should at least try to show some courtesy and appreciation to people who have travelled half way round the World to help us do correct Kendo.
