The Goju Ryu Kenkyukai is very friendly, and values Sensei Taira, So when we go to seminars, people bring gifts. Cool. That's very nice. He does value the sentiment.
So - if Sensei drinks all that, there won't be much training. If he doesn't drink it all, he's not taking it home on an airplane. There's a limit to what he can take into Japan.
There's a couple of other things there on the bottom shelf, gifts that weigh a kilo or more. Sensei travels with a small bag! And if you've trained at Sensei's home dojo - it's small and already a bit cluttered!
So - a suggestion. Keep it small, keep it seemly. If you want to present a gift then make it small, and light, and not booze! If it has to be high value for some reason, make it cash ;-)
