Yamadamatsu’s Shoyo is quite enlightening, hence the name as it is written here means “Shining Light”. This coil has a strong initial top note of both vanilla and a resinous labdanum scent, combined with at first a woody, salty aloes wood that eventually fades to a mid/base note of cedar. There’s not much else to say other than this is a wonderful scent well worth the price.
Shigei on the other hand is all about the wood. Unlike its predecessors, this coil forgoes any blend and instead contains a straight blend of Vietnamese aloes wood, with a top note of buttery, salty aloes wood to its scent. With a price of 10$ per coil, it is definitely a incense you will want to sit down with and study.
