I know this question was asked already several times here but ....
The option always advised here does not work for me, the next school room option would be about 400km to travel.
So I need advice what choice of interactive program is best for me.
Given the price I want to be pretty sure I buy the right one.
I aim at learning enough to converse on a basic level, i do not plan to move to Japan, but I plan to travel not the tourist routes, so polite greeting, asking the way, choosing the right restroom, reading timetables and so on is what i am looking for.

I know the advice is always here to learn from someone who learned Japanese in Japan or learn it in Japan, but i donot have enough time to spend to travel to Japan and learn it there before leaving Tokyo, AND i do not care at all to stick only to the tourist haunts, i plan to learn about woodcrafts mainly, i am learned cabinett maker and interested in how things are done in Japan there, I am already using a few tools i consider superior to european ones so this is my main reason to travel to Japan.

If someone knows an cabinet maker in Japan who is fluent in english and eager to teach a few tricks of the trade to an curious european all the better !

(I am offcourse already quite happy to sit in an corner and observe quitly, but if i am able to ask questions and understand answers it is more than i hope for!)

My idea is to learn enough Japanese spoken and written before i travel to Japan so an Japanese can explain to me technical terms in woodmaking in Japanese, i doubt there are language courses aimed at cabinett makers.

THANKS!
