nissan ichigo factory

It has the GTR engine build.
There are a few others on the left side too, like yokohama (15mins on shinkansen from tokyo).
Or visit the Nismo factory at Omori, I think there is a JR Omori or subway there.
Asahi breweries:
One in Nagoya is:
318 Nishikawahara-machi, Moriyama-ku, Nagoya, Aichi 463-0089
TEL 052-792-8966
Catch train from Nagoya station to Shinmoriyama station (platform 7 or 8 - JR Chuo Line)
Catch the local one not the rapid one as only the local one stops at shinmoroyama.
Then follow the map and walk about 15mins to the place.
