Higashi

Pressed-sugar sweets entered Japan from Ming China in the Muromachi period through the Japan-Ming trade and spread alongside the rise of chanoyu, the way of tea, as a sweet to set beside the bowl. The name rakugan has two competing explanations: one traces it to the Chinese confection nanrakukan (軟落甘), from which the character for "soft" was dropped, while the other likens the dusted, pale shapes to a flight of geese descending onto the lake in "Katata no Rakugan," one of the Eight Views of Omi. Refinement came in the Edo period, when carved molds, refined sugars, and seasonal forms turned a simple pressed sweet into an art of the tea room. Its prestige is settled in the so-called Three Great Confections of Japan — Koshi-no-yuki, Choseiden, and Yamakawa — all of them rakugan.

A piece of rakugan looks like fired porcelain and breaks with a faint dry snap, then collapses on the tongue into a cool wash of sweetness that is gone before you can chew it. There is no chew at all; the whole point is the dissolve, clean and quick, leaving only the toasted, faintly grain-like scent of the rice flour behind. Wasanbon higashi takes this further still, melting so finely it feels almost weightless, with a rounded sweetness softer and less sharp than ordinary white sugar. Taken before the matcha, its bone-dry sweetness is the deliberate foil to the bitter, frothy tea that follows.

Higashi keeps because it is, in effect, a slow sugar candy: with moisture only in the low single-to-low-double-digit percentages — far below the roughly thirty percent and up of fresh namagashi — there is too little free water for spoilage, so well-kept pieces last for months. Rakugan is built not by cooking but by compression. Sieved sugar and roasted glutinous-rice flour are dampened with a trace of syrup (shitori) so the grains will cohere, packed hard into a carved mold, and knocked out to hold a crisp shape that then dries fully. In the mouth, the lightly bound crystals simply redissolve, which is why it melts rather than chews. Wasanbon makes the cleanest melt of all: its repeated kneading and pressing yield exceptionally fine crystals, and small crystals dissolve faster and feel smoother than the coarse grains of ordinary sugar.
