This was an absolutely lovely cruise around Matsushima Bay to see the islands scattered around. The guide provided commentary only in Japanese, but there were maps provided in English. Tours are about 50 minutes as noted and leave every hour. One handy note - the Matsushima Rest House has several medium-sized coin lockers available for storage, which was very convenient! I was able to fit a carry-on roller suitcase plus a backpack into the 500 yen locker. Sitting at the tea house overlooking the water was very lovely as well. Highly recommended experience!
