In a statement just posted by parent company CyberFight Corporation, it was announced that Go Shiozaki appears to be done with Pro Wrestling NOAH. Contract expires today (9/30 Japan time) and will not be renewed. The promotion has also confirmed this on their website. No word yet on Shiozaki’s future plans (his last social media posts appear to be from 3 days ago) and he has not yet been removed from NOAH’s roster page on their website.
More as it becomes available.
UPDATE: A translation of comments by Shiozaki seem to indicate he will continue his career somewhere as there was no mention of retirement (he’s 43 with 20 years experience).
