Sui, The Joyous Lake
The Judgement of the Hexagram
Gathering Together. Success.
The king approaches his temple. It furthers one to see the great man. This brings success. Perseverance furthers.
To bring great offerings creates good fortune.
It furthers one to undertake something.
From commentary on “Sui, The Joyous Lake” in Hexagram 45, I Ching, Iwanami Bunko
The word “萃(Sui)” in the name Sui-Suwako means “to grow lush like thriving grass.” This was selected from “Sui, The Joyous Lake” in Hexagram 45, I Ching, a classical Chinese text.
“Sui, The Joyous Lake” evokes the image of fresh water nourishing the earth — a symbol of fertility and abundance. As the soil is enriched, plants flourish, living creatures gather in search of blessings, and the cycle of abundance continues.
We chose the name Sui-Suwako out of a desire for the inn to become a place where guests gather in Suwa to cultivate memories overflowing with vibrant abundance.
When you step away from the hustle and bustle of daily life and gather with loved ones, you are sure to experience a time of peaceful relaxation.
