Digest · Issue 005 · 21 September 2026

Japan has been buying magnet capacity in Southeast Asia

The first issue written in the week it covers, and it is mostly Japan — not because Japan had a busy week, but because a pass through the Japanese-language record turned up a funding program that English-language coverage has never once mentioned.

Peculiar Materials LLC · Covering 15 to 21 September 2026. What this issue skips, so nobody mistakes it for complete: prices, which move faster than a weekly can usefully report and are better bought from somebody whose whole job is assessing them; magnet research, which gets its own treatment when something actually ships; and China's domestic producers beyond their filings, because the useful signal there is quarterly, not weekly.

Revised 22 September 2026. Two items were added after the first full run of the crawlers surfaced them: Arafura's offtake extension of 18 September, and Korea Zinc's environmental clearance of 21 September, together with the separate and much smaller thing Korea Zinc is actually doing in rare earths. The original eight items are unchanged.

Read it

The digest is free and goes to whoever asks for it. Put in the address you want it sent to and this issue opens in the same click — already on the list? The same box lets you straight back in.

Your address, the date and which page you came from. Nothing else, no tracking pixel in the email, one click cancels for good, and it is never sold, rented or shared. Mondays, when the mailing is switched on — I am not going to pretend it already is, and this line changes the day it does. Until then new issues appear here and in the feed. Prefer to give no address at all? The feed carries the same summary you are reading and tells me nothing.
