The right is a Housui(豊水;it means abundant water) pear and the right is a 20th century pear. The Japanese pears are rich in water and crisp texture is really good. I love them very much.
I remember a Swiss boy who once lived in Japan in his childhood was really impressed by the delicious Japanese pears.
If you haven't eaten any Japanese pears, I assure you, it worth trying. The more expensive ones you get, the more assured the taste is.
Iwa means rock and shu means cream puff which Japanese call "shu cream". Setana town is situated northwest of Hakodate and it takes about three hours or so by car. you can get this iwawhu at Koda kashiten(甲田菓子店) on Tuesday, Thursday, Saturday, Sunday and holiday. They say you should eat iwashu within one hour to enjoy crispy touch of puff shells and fresh cream.
From Setana to where I live it takes at least three hours, but still it tasted pretty good.
Iwashu is very popular not only local Setana people but also others like us. So I recommend to call in advance and make reservation.
Address: 343-1 Honmachi(or Honcho), Setana-ku
You can find the shop easily. In Setana, there are three huge rocks named Sanbonsugi-iwa which means "three cedar tree rocks" that stand near the shore. Try to get to the coast and there is only one street to get there. The confectionary shop is on you right before reaching the coast.
I love Iwashu and never go to Setana without dropping by Koda kashiten to buy some sweets.
