There is a place called ACME Bullet Company in Mebane that makes batches of Jap ammo periodically. I have bought some of his 7.7 Jap before. He may make the 6.5 too. It might be worth calling and asking. Graf and Sons has PCI 6.5 Jap in stock for $28.99 a box (+ $7 flat fee shipping). That is not bad pricing, but be careful as PCI load quality can be absolute sh*t sometimes. With their ammo I have seen lots of squibs, out of spec (too long/too short), primers in backwards, etc. Just be careful and inspect it VERY carefully before shooting it.
