若干あやめは早かったかもしれません。もう少し後の方が咲き乱れているかも？黄色いあやめもあるんですね！ Iris maybe a bit early to go now. (Visited June 7th) First time to see yellow iris there though. The place isn’t too big but it has statue of kappa (the legendary myth) Nice and serenity place.

I think main topic should be Ushiku Swamp. This garden's on North East of the Swamp. It's very cold here in winter. But good to see it. There're some people fishing here under the bridge. The fishing fee is 400Yen for a day or 4,000Yen for a year.
