There are some wild planes used for joinery. You can probably buy most of them from Japan Woodworker these days but you may find some bargains, especially if you'll be there long enough to track down a real old tool store or just buy things on ebay there and avoid the overseas shipping costs. Of course Japanese websites are pretty strange if you can't read Japanese.
Hitachi, Makita and others make professional carpentry machines that are seldom exported. There's a YouTube channel for Ishitani furniture that features a workshop outfitted with vintage Japanese machinery.
