Nishii recommends these two LOST board models for small waves in midsummer!
Lost "FISHQUEST 2" model

The rounded nose provides stability when paddling and moves forward smoothly without any wobble. The rounded, thick rails on both side rails of the bottom allow the board to lean easily as if riding a thin board, and the stepped elevator wings assist in turns. The long VEE bottom design that extends from the tail end to the front fin is a very well-designed combination, and even though it's large, it moves well, so we recommend riding it with a larger board so that it feels like it has more buoyancy.

For example, even someone weighing around 50 kg can control a 5'10" size. We recommend riding a larger board, so to make dolphin-throughs easier, the dolphin grab makes it easier to grip the rails and dive the board deep under the water. It may be difficult to convey how easy it is unless you actually do it, but it really is easy to dolphin-through.

Thinner sizes are also available, and we recommend the thinner size for those looking for more action, but we recommend the thicker size for those who are not confident in paddling.

The other one is,
Lost "ORCA" model
This board really takes off as quickly as a long board. It's perfect for the small waves of the super crowded summer season, where it really shines in crowded waters. Recently, when the water got crowded on the ORCA, I was paddling to a peak a little further away, and I ended up sliding off into a wave I hadn't intended to ride, which surprised me.

The bottom is dome-shaped, the opposite of a concave, and although it is the widest of LOST's models, it moves smoothly and easily, making it a board that makes small waves fun. Some people who purchased the 5'10" find that it moves well, so they then purchase the next size up, 5'11", and because it moves well even though it is larger, they are able to further improve their take-off and paddling performance and enjoy surfing.

This is a Japan-only model that we highly recommend to those who often go surfing in places like Shonan, Kokufu Beach, and Isonoura.
This board will remind you that surfing can be fun even in small waves.

Nishii recommends both of these models, which feature a wide bottom design that makes it easy to maneuver thick boards.
This board is a theoretically designed board from MAYHEM, which is said to be the best in the world when it comes to shaping edgy fish.
