Now that is what I call Life-Fi. Fun looking system, in a fun looking room, in what looks like a dynamite domestic spread.
I quit my drinking and am now a coffee guy. Your place looks like a spot where I could definitely down a few cups of Peets coffee. For Japanese music, check out Guitar Wolf or Boris (fuzzed out hard rock / psych / punk / garage stuff).
Also, when in Tokyo, check out Cafe Lyon. It is an audiophile cafe near the Love-Hotel district (cant remember the name right now). They play only classical music there, and the coffee is only decent, but the system and ambiance are pretty cool.
