Man I love BBQ.
I’d have thought that good American-style BBQ would be hard to find in Tokyo but it’s actually not so bad, there’s a couple stellar places. The military folks here have it even better where the bases do some truly world class BBQs and sometimes open them to the public.
Even so, there’s nothing like home BBQ, and for a few years my father in law and I have been pretty serious about it, we each have decent (if small) gas grills. He bought a smoker last year as well, so we’ve had nonstop amazing smoked chicken and other meats more or less whenever we want it.
Also, Japanese charcoal (used primarily for yakiniku and yakitori) is amazing. Really really good stuff. Sakura wood works well for smoke as well. Hickory is available here too.
Japanese BBQ is pretty amazing itself, people here love to do it, lots of rec areas have them.
