The Imperials obviously won the Boshin War, and came to accept that seclusion just wasn't workable for Japan to progress. So they came to accept the West, just not to the same extent as the Shogun wanted. Japan fought its first foreign war since the invasions of Korea in 1904 against Russia, after signing an alliance with Britain. So you could say that after the Emperor had been in power for about forty years Japan had opened itself to the West.
Then again, in WWII many Japanese soldiers turned away from using guns to using swords. So traditionalist values still continued.
