Yakuza 1&2 HD Edition, which was spotted on a Sega Japan release schedule last week, will launch in Japan on November 1, according to Famitsu (via Andriasang).
In addition to the HD visuals, both games will benefit from reduced load times, eaten food will show up on a check list, while the item box can be managed in phone booths.
As a pre-order bonus, the Yakuza collection will also feature special packaging based on the PS2 originals.
Sega is yet to confirm whether or not the games will release in the West.
It launches ahead of December's Yakuza 5, which was confirmed by series creator Toshihiro Nagoshi last year.
It will be developed by Nagoshi's Yakuza Studio, which recently completed work on Sega's squad-based shooter Binary Domain.
The plot will follow directly on from Yakuza 4 across locations such as Tokyo, Fukuoka, Osaka, Sapporo and Nagoya.
