The starlet earned his first call-up to Alberto Zaccheroni's squad an impressive start to his time with Premier League club Bolton
The 19-year-old will join Yuto Nagatomo, Mike Havenaar, Tadanari Lee, and other Europe-based internationals just days after after an all-domestic Japan squad beat Iceland 3-1 in an international friendly.
Miyaichi scored his first English goal last weekend in an FA Cup win against Millwall in just his second match for the Wanderers after joining on loan from Arsenal in January.
Jubilo Iwata veteran Ryoichi Maeda was left off the squad despite scoring Japan's first goal in the Iceland match just two minutes into play. Jungo Fujimoto and Tomoaki Makino, who also scored in the match, both received call-ups.
Other notable absences include Keisuke Honda, who recently returned to play for CSKA Moscow in Champions League action against Real Madrid, as well as Dortmund's Shinji Kagawa who rejoined his team in practice this week after sustaining an injury.

Goalkeepers: Eiji Kawashima (Lierse), Kaito Yamamoto (Shimizu S-Pulse), Shusaku Nishikawa (Sanfrecce Hiroshima)
