Kagamigi
Kagamigi (the best translation I could find into Japanese for "mirror chess")* is my first foray into making Shogi variants, and the start of a "family" of variants featuring the same principle.
The idea here came when I noticed how many "left/right" pieces there were in Shogi. Not all were called that (the Divine Turtle/Divine Sparrow and Great Dove/Center Standard pairs used in this game being among the exceptions), but it did make me think about ways to feature as many of them in a single game as I could.
This Variant is actually just the beginning; I plan to make this the smallest of a series, with the establishment of each version leading to the creation of a new one with three new spaces in each direction, until I run out of left/right pieces to add.
*With any due apologies to native Japanese speakers if I got that wrong.
Setup
Setup is on the traditional 9x9 square Shogi board, even though most pieces are very different from what you'd find in a regular Shogi game.
The Interactive Diagram below shows the setup, with the Pieces list below to be used as a guide. Currently it uses only icons (both single and compound) from my SVG set; hopefully, Mnemonic pieces and perhaps even traditional Kanji-stamped Shogi pieces will be added soon.

Rules
Except where noted otherwise, the normal rules for shogi apply here, including the use of drops.
Promotions: All pieces that promote may do so upon reaching the opponent's Pawn Row (7 for White, 3 for Black) or beyond. Promotion is mandatory upon reaching the furthest row (9 for White, 1 for Black).
Promoted pieces, when captured, immediately demote to their original form.
Notes
The Blue Gecko is actually a creation of Adrian King, for his game Jupiter. I created the Purple Finch as a reflection, originally just on principle though the two pieces do go nicely with this game.
Similarly, the Silver Pashtun (along with its Gold cousin) was invented in 2007 by Charles Gilman, and featured in his variant Pashtun Shogi (presented on his page for Shogi-set Nearlydouble Variants).
