Beautiful place! I visited here on sakura season this year but it was extremely crowded hence didnt do the boat ride. The boats can be hired for 500 yen for 30 minutes and 1000 yen for an hour ride in either a cycle boat or a row boat with a maxmimum capacity of 3 person in eqch boat. It is now Autumn but it still looks so beautiful! Highly recommend this park. Please be informed that you cannot do boat rides on December, January and February. It is open the rest of the days.
