This great piece of Japanese manufacturing is an excellent Tsunoda.
The Tsunoda brand mostly built bikes for other brands like Lotus but also made some really nice stuff under its own name. The frame is a very modern design for its time - not in the way the lugs are chromed but in the way they are shaped and the joints are made. The technical thinking is reflected in the choice of parts - mainly from Shimano's Dura Ace Groupset. A nice choice for historic races like L'Eroica! The long arm of the rear derailleur allows the installment of big cogs for climbing. And the special design of the AX-crankset allows riders to feel comfortable on this bike who usually ride a bike in size 57-58.
