The brewing method will be tweaked to give Super Dry a more distinctive, "faint-hop" aroma, the company said in a release. The trademark silver logo and can will also get a makeover, with the changes to go into effect from mid-February.

The changes are a response to increasing competition in Japan's shrinking domestic market, the company said.

Asahi Group is Japan's biggest beer maker with a near 40% share of the market.
