The news comes as the Mariners learned they'll be without outfielder Ben Gamel for four to six weeks due to a strained right oblique muscle.
Suzuki came to Seattle in 2001 after playing 9 years in Japan.
If a job in the majors had not opened up, he was planning to play in Japan for the 2018 season. Another returning outfielder, Guillermo Heredia, is coming off shoulder surgery and is being worked in slowly. Ichiro spent 12 season with the Mariners.
In his third season with the Miami Marlins in 2017, Ichiro was mostly a pinch-hitter who finished with 196 at-bats and a.255 batting average, three homers, 20 RBI, a.649 OPS and -0.3 WAR.

At least 76 pro-regime fighters and 43 rebels from Jaish al-Islam have also been killed in clashes since February 25, it says. One resident estimated that thousands of people were on the move and seeking shelter in areas further from the frontlines.
In November, the Marlins chose to declined their $2 million option on Ichiro, making him a free agent.
Again, nothing is yet official, but the two sides are talking and we could see Ichiro in Peoria soon.
The Mariners could seek a free agent like Jon Jay or Carlos Gonzalez, though would likely offer just a one-year deal.
Of course, there is an actual baseball reason for the move. The future Hall of Famer has 3,080 hits over his 17-year major league career.
