Abundant in summer and in moderation in winter. This tree doesn’t like pools and appreciates it if you pulverize the leaves with water (not hard water).

Every 3 or 5 years, at the beginning of spring.
100% Akadama, or a mixture with 30% of volcanic earth.
Pruning and pinching

Throughout growing seasons, pinch tips of new shoots with fingers for compact shape, but not too hard at any one time as this encourages juvenile, needle-like growth.
The whole year with preference from October to March
Of all the varieties of this species the Itoigawa is the most popular because of its small leaves of yellow-green brilliant colour and the hardness of its wood, which is very appropriate for the realization of jin-shari.
