Lotus flowers have begun to bloom early in the lotus pond. There are many people around. In the sand pool over there, snipes are eagerly picking at something. If looking closely, I can see that there are Hishi nuts, water chestnuts. And the young small leaves of the Hishi spread all over, and two yellow flowers are blooming in one corner. No one has noticed. Hishi nuts bear fruit in the fall, and they are covered with a hard shell with two needles. Its taste is just similar to chestnut. They say that Hishi with the hard shell are the necessity for the Ninja of Iga.

蓮池に早々と蓮の花が咲き始めました。周りは人だかりです。その向こうの砂だまりでタシギがせっせと何か餌を啄んでいます。よく見ると菱の実がいっぱい散らばっています。池には小さな菱の若葉が広がり、その片隅に黄色い二輪の花が咲いています。誰も気付いていません。菱の実は秋にできますが、針のある硬い殻に覆われていて、中には栗の味とそっくり実が詰まっています。硬い殻は伊賀の忍者の必需品だったそうです。
