In the bag

Every item links to where it was reported. When the reports are thin or disagree, we mark the item unconfirmed and say why, rather than guess.

  • Driver

    Model
    Bridgestone BX1LS

    UnconfirmedSources conflict, so under our rule this is unconfirmed. We show the listing from Bridgestone’s own player page and its Aug. 3, 2026 release on the win, the highest-ranked sources. GolfWRX's Aug 3 Tour Tech Rundown and Golf Reviews Guide list a B-Limited B1LS at 9.5° instead. GDO, ALBA, egolf and Sportsnavi agree with Bridgestone. The loft and shaft come from GDO and ALBA.

    Specs
    Loft 9° · Shaft Mitsubishi Chemical Diamana BB 53 · Flex S · 45 in, D1.5 swingweight (egolf)

  • Fairway

    Model
    Bridgestone B1ST

  • Hybrid

    Model
    Bridgestone BX2HT

    UnconfirmedSources conflict, so under our rule this is unconfirmed. We show the listing from Bridgestone’s own player page and its Aug. 3, 2026 release on the win, the highest-ranked sources. GolfWRX and Golf Reviews Guide list a single B2HT 3-hybrid instead. GDO and ALBA agree with Bridgestone.

  • Irons

    Model
    Bridgestone 241CB

    UnconfirmedSources conflict, so under our rule this is unconfirmed. We show the listing from Bridgestone’s own player page and its Aug. 3, 2026 release on the win, the highest-ranked sources. GolfWRX and Golf Reviews Guide say 4-PW instead. GDO and ALBA agree with Bridgestone, and with two hybrids in the bag a 4-iron would make 15 clubs.

    Specs
    Shaft N.S. Pro 850GH · Flex S · 5-PW

  • Wedge

    Model
    Bridgestone Biting Spin 2

    UnconfirmedSources conflict, so under our rule this is unconfirmed. We show the listing from Bridgestone’s own player page and its Aug. 3, 2026 release on the win, the highest-ranked sources. GolfWRX and Golf Reviews Guide list Tour B BRM2 wedges instead. GDO and ALBA agree with Bridgestone. The wedge was unreleased when she won (egolf); Bridgestone gives a Japan release date of Sept 4, 2026.

    Specs
    Loft 48°, 52° · Shaft N.S. Pro 950GH · Flex S · egolf: the 48° sole is nearly flat and the 52° has trailing-edge relief

  • Wedge

    Model
    Bridgestone Biting Spin prototype

    Tour-only head. The nearest model you can buy: Bridgestone Biting Spin 2 58°, sold in 8° and 12° bounce. Bridgestone's product page gives a Japan release date of Sept 4, 2026..

    UnconfirmedSources conflict, so under our rule this is unconfirmed. We show the listing from Bridgestone’s own player page and its Aug. 3, 2026 release on the win, the highest-ranked sources. Bridgestone marks it a prototype, as do GDO, ALBA and Sportsnavi; GolfWRX and Golf Reviews Guide list Tour B BRM2 wedges instead. The shaft, N.S. Pro 950GH S, comes from GDO’s winner’s-bag story and ALBA.

    Specs
    Loft 58° · Shaft N.S. Pro 950GH · Flex S

  • Putter

    Model
    Piretti Potenza LN GSS, tour-only (the name varies by source)

    Tour-only head. The nearest model you can buy: Piretti Potenza 2. Piretti Japan's online shop sells one-off 'Tour Only' putters. When we checked, it listed a Potenza 2 long-neck Tour Only in 303 stainless; her putter is reported in GSS..

    UnconfirmedFive Japanese outlets report a Piretti tour-only GSS putter: GDO's setting page and winner's-bag story, egolf, ALBA and Sportsnavi. egolf says she put it in play this season. The exact model name differs between sources. GolfWRX's Aug 3 rundown and Golf Reviews Guide list an Odyssey White Hot OG 2-Ball instead. Their other listings look outdated (see the driver note), but no manufacturer source settles the putter, so it stays unconfirmed.

    Specs
    GSS head. egolf: 'Potenza 2 LN GSS'; ALBA: 'Potenza LN GSS'; GDO: 'GSS Tour Only'

The ball

Bridgestone Tour B XS (2026), yellow

UnconfirmedSources conflict, so under our rule this is unconfirmed. We show the listing from Bridgestone’s own player page and its Aug. 3, 2026 release on the win, the highest-ranked sources. Golf Reviews Guide lists a Tour B X instead. GDO lists the 2026 Tour B XS, egolf says she has played a yellow Tour B XS since junior high, and Today's Golfer quotes her on the yellow ball.

What changed since the last start

  • None reported for the AIG week itself. The latest reported changes came earlier in 2026: egolf says she put the Piretti putter in play this season, and GDO says she switched her 48° and 52° wedges to the then-unreleased Biting Spin 2 in early May, at the NTT Docomo Business Ladies. GDO's setting page from her June win at the Miyazato Ai Suntory Ladies lists the same clubs, shafts and ball she used at Royal Lytham.

What wasn’t reported

The reports we found didn’t cover these, so we’ve left them off the bag rather than guess.

  • The putter’s model name differs between Japanese sources, and two English sources name a different putter.
  • Wedge bounce, putter length and loft, and grip details aren't reported.

Our take

This is Tour Weekly’s opinion, not the player’s or any brand’s.

Shiho Kuwaki won a major with a yellow ball, and per egolf she's played a yellow Tour B XS since junior high. That's the first lesson: find a ball you can see and trust, then stop auditioning others. Her driver story is useful, too. In egolf's gear story she says she used to spin the ball too much, and the low-spin BX1LS brought her spin into the right window. If your drives balloon and fall out of the sky, a low-spin head is worth a fitting. It clearly suited Royal Lytham: egolf says her driving found a bunker only twice in four rounds on a course famous for its 174 pot bunkers. And her 48° Biting Spin 2 wedge earned its spot, sticking her third shot to about a meter on the first playoff hole to save par.
