Most looking forward to picking Jumbo grapes and white peaches, and really eat very full😂, fruit quality is also very high, next time to remember to eat Jumbo grapes have to leave the stomach to eat peaches, the whole trip time arrangement is appropriate, the weather is good, the scenery is very beautiful, can go to so many attractions in a day very satisfied. It’s also convenient to gather and disband in Shinjuku.
