Hi,
I'm the other Amiga owner in Kyoto
OSS542 and I meet semi-regularly to purloin parts from one another. I still have an A4000T -128mb fast - Retina BLTZ3- 640MO - PCMCIA-SCSI drive (wrote the driver!) (Aminet scsi_pcmcia.lha) CD reader & Yamaha 4-4-16 burner - IOBlix - TBC-III - Neriki desktop genlock - 1.44mb floppy..... two UW-SCSI drives 10 gig.
I moved to Japan in '93 and an Amiga 2000 was my lifeline to civilization via the internet - aah the memories of configuring AmiTcp and ...ppp
I used to regularly correspond with a Japanese guy in Aichi (way north of Kyoto) he lived in a dogbox of a flat and had I think 4 or 5 A4000's, same number of A2000's A12000's and a couple of A500's turns out that he couldn't even invite me to come and see them as he was sleeping very close to his front door with only a snake aisle to the toilet. He showed me how to read/write/print Japanese on an Amiga.
Way back, years ago most TV commercials in Japan (for a short period) were made with Amiga/Toaster setups.
There is as OSS542 says, a Japanese Amiga Users Gr oup but there is also a BBS still operating but the name escapes me for the moment.
I used my A4000T with Pagestream and the help of ShapeShifter to create a new phonetic English teaching system.
I owe a lot to my Amigas (gave my last A2000 to OSS542)
My A4000T gets fired up every night to keep it alert but it also now has a companion on the other side of the desk... a 1.25Ghz MDD Mac with 1.5gig mem & DVD burner and a poorly implemented Amiga emulated - but fast.
They complement each other but the A4000T still beats the Mac every time booting up.... 25 seconds flat.
I've given up trying to explain what an Amiga is to Japanese visiting my home - most still don't know what Linux is yet

But the Japanese when they get their minds made up are rabid and ferocious collectors. I should imagine a night with a bunch of Japanese Amiga nuts would be overwhelming in it's intensity.
All in all, quite a nice, civilised, fun bunch of people
Viva Amiga
:-D
