Houston Astros pitcher Tatsuya Imai has pinpointed an unexpected culprit for his recent arm fatigue: the challenge of adjusting to life in America. The Japanese right-hander, currently on the injured list, received positive medical news with no significant structural damage found. However, Imai believes the off-field transition from his seven-year career with Japan's Seibu Lions to Major League Baseball has taken a physical toll.

"The travel is different from Japan," Imai explained through an interpreter. "The timing when the players eat... He thought it would be the same." In Japan, players typically dine at the hotel after games, while in MLB, meals are often at the stadium. This seemingly small shift in daily routine, compounded by a new country, language, and culture, can disrupt the meticulous rhythms elite athletes rely on.

This cultural adjustment is a well-known hurdle for international players. While the game between the lines is familiar, everything surrounding it—from media responsibilities to the feel of the baseball itself—is different. Some players adapt seamlessly; for others, the life changes can impact performance on the mound until a new normal is established.

For the Astros, who signed Imai to a three-year, $54 million deal this past offseason, helping him assimilate is a new experience. While the franchise has had Japanese players before, Imai is the first they've signed directly from Japan's Nippon Professional Baseball, making his smooth transition a priority for the team's success.

Imai views this IL stint as a necessary pause to reset, build arm strength, and fine-tune his routine. "He thinks it's a positive thing to try and adjust and try to become better," his interpreter stated. For a player whose early outings have been rocky, including a recent start where he walked four of seven batters, mastering the American lifestyle might be just as crucial as mastering American hitters.
